In two successive seasons (2017/ 2018 and 2018 /2019), the trends of ten wheats (Triticum aestivum L) genotypes were assessed to drought stress at the Agricultural Research Station, Faculty of Agriculture, Assiut University, Egypt. Drought obtained by skipping four irrigations of seven irrigations of control. Generally, droughts caused reduction for all the estimated morphological and physiological traits. The data revealed that the plant height was greatly affected in AIL134 and Sids12. Spike length, 100 grains weight and grains yield per genotype were adversely affected in AIL103, the former was affected in Sids12 and the middle one was reduced in Giza168 under drought stress. Also photosynthetic pigments were reduced in AIL108, AIL112 and in the Egyptian genotypes (Giza168 and Sids12). On the other hand, these traits were moderately affected under drought in AIL120, AIL129, AIL142 and AIL148 genotypes. Statistical analysis revealed that the drought was significantly affected all traits except chlorophyll b contents. Also the differences between the genotypes were significant. Most of the interactions between the genotypes, treatments and years were significant with some exceptions as those for spike length and weight of 100 grains.

Experiment was carried out throughout two successive seasons of 2016 and 2017 on Manfalouty pomegranate trees grown at the Experimental Orchard of Assiut University, Faculty of Agriculture. Thirty six uniform trees (9 treatments x 4 replications) were chosen. The spraying treatments were: Micronutrients at the concentration of 2.5 and 5%, amino acid mixture at 1 and 2%, and Potassium solution at 1.5 and 3% and calcium solution at 2.5 and 5%. The obtained results revealed that most of the treatments increased total yield weight. The most effective treatments were micronutrients at 5%; amino acids at 2% and potassium. All the treatments significantly decreased fruit cracking comparing with the control. The most effective treatments were calcium and potassium spraying. The present data also suggested that spraying with micronutrients and amino acids at 1% produced the best fruit quality. From the obtained results of the present study it could be recommended that: Spraying micronutrients and amino acids for obtaining the best fruit quality with reasonable yield and healthy fruits. For decreasing the fruit cracking and increase the fruit firmness it could be recommended that to spray the fruit with calcium and potassium.

The current investigation was carried out during 2018 and 2019 seasons to study the effect of some fertilizer practices on yield, fruit quality and some mineral content of Khalas date palm grown in a private farm, Luxor Governorate, Egypt. Results showed that significant improved due to use slow release fertilizers as well as comparing total soluble fertilizers in terms of vegetative growth and nutritional status yield, bunch weight and fruit quality during both seasons. Using 600 g of N and 300 g of K via slow release fertilizers form had improved the growth and nutrient status of date palms as well as increase the fertilization efficiency. Also, it could be suggested that fertilizing by 60 to 75 of RDN and RDK via slow release fertilizers to improve the nutrient status of palm and gave the high bunch weight and consequently high yield/palm. Moreover, these fertilization treatments via slow release form gave high yield with good fruit quality compared with using 100% of RDN and RDK via mineral source during both studied seasons. On the light of previous results, it could be concluded that Fertilizing the palm by 60 to 75% of recommended doses of fertilization via slow release form to get high yield with good fruit quality. In addition, reduce the environmental pollution and increase the fertilization efficiency.

Bañoc
Sweet potato production is affected with different problems related to incidence of insect pests and diseases, and erratic climatic conditions which hamper the production by 41.33 to 42.22 percent, respectively. Thus, this study which was conducted aimed to determine the effects of soil solarization and micro-fertigation technique on the yield performance of sweet potato; determine the effect of nutrient management under micro-fertigation technique and evaluate the profitability of sweet potato production as influenced by soil solarization and micro-fertigation technique. This was laid out in split plot arranged in a Randomized Complete Block Design (RCBD) adopting three replications with two mainplots and four subplots. The main plot was designated as M1 – with solarization and M2 – without solarization while subplot treatments were designated as follows: S0 – no fertilizer application (control); S1 – conventional application of inorganic fertilizer; S2 – application of inorganic fertilizer through micro-fertigation and S3 - application of Aloe vera bio-organic liquid fertilizer through micro-fertigation. Soil solarization controlled weed population and produced higher total root yield of sweet poptato. Adoption of micro-fertigation technique increased root yield and produced larger and less-damaged roots. Morever, the application of aloe vera as bio-organic fertilizer enhanced higher root productivity and contributed lesser reduction of root yield caused by pests and diseases. Thereby, soil solarization with aloe vera application under micro-fertigation technique was the best option for sweet potato production to enhance root productivity, income and protection of plants from pest and disease damage especially in areas with unstable climatic conditions.

The present investigation was conducted at El-Mattana Agricultural Research Station, Luxor Governorate, Egypt during two successive seasons 2018/2019 (plant cane) and 2019/2020 (first ratoon) to screening of eighteen sugarcane genotypes s for the lesser sugarcane borer, smut, streak and mosaic diseases resistance under natural infection and elimination of sensitive genotypes from sugarcane breeding program and to evaluate the performance of some sugarcane genotypes based on principal components analysis biplot and genetic components; heritability and genetic advance for the studied traits. The experimental design used was a randomized complete block design with three replicates. Results show all studied traits varied significantly among evaluated different genotypes in the plant cane and first ratoon. Cane yield of five and two genotypes in plant cane and first ratoon, respectively, gave significantly the highest mean values of cane yield as compare with check variety. Bored stalks% and bored joints % varied significantly among evaluated genotypes. It found high positive correlation between bored stalks% and bored joints and brix% in the positive direction. Plant height and stalk diameter were positively correlated with cane yield, not only smut, mosaic and streak diseases but also bored stalks and bored joints were negatively correlated with cane and sugar yield and negatively correlated sucrose%, purity% and recovery%. The differences between the estimates of GCV and PCV was comparatively narrow for all the characters (except stalk diameter and Mosaic disease) suggesting the possibility of affective selection of these traits and indicating high prospects for genetic progress through selection under the conditions of this investigation.

The effect of chemical fertilizer (NK) and humic acid on top length, root length, root diameter, leaf area per plant, top fresh & dry weight and root fresh & dry weight of fodder beet (Beta vulgaris L. c.v voroshinger) was carried out in the Experimental Farm of Agriculture Faculty, South Valley University at Qena during the two seasons of 2016/2017 and 2017/2018 on sandy soil. A field experiment was conducted using a randomized complete block design in split- plots arrangement with three replications. Humic acid treatments were arranged in main plots while, fertilization treatments (NK) were allocated in sub-plots. The highest mean values of most previous traits were obtained from fodder beet plants which were supplemented by soil application of humic acid and 90kg N+100kg K2O /fed. (H1F9). Based on these results, it is recommended to adding humic acid on soil and fertilization with NK by 90 Kg N + 100 kg K2O per Feddan for fodder beet under similar soil and climate conditions.

Multiple traits selection in bread wheat under drought stress and normal irrigation
Rasha
Mahdy
The genetic materials were F2, F3, F4 and F5 generations of the cross “Giza164/Sids4” of bread wheat. The experiments were conducted under drought stress and normal irrigation. Three cycles of single trait selection for grain yield/plant (GY/P) and five models of desired gain selection index (combinations from seven traits) were achieved in both environments separately. After the third cycle of selection, the selected families for the six types of selection under drought stress, and the selected families under normal irrigation were evaluated under both environments. The GCV in GY/P decreased from the F2 to the F5. The remained variability in GY/P for the five selection indices was higher after the three cycles of selection than the single trait selection for GY/P. Heritability estimates as calculated from regression of F5/F4 generations for the traits under selection pressure were higher under drought stress than under normal irrigation except few cases. The observed gain increased from index1 to index5, and all indices were better in improving GY/ P than direct selection for GY/P. It could be concluded that selection index was better in improving grain yield than single trait selection for GY/P. Furthermore, selection under drought stress (antagonistic selection) in these materials was better than selection under normal irrigation (synergistic selection) in improving GY/P either selection evaluated under drought stress or under normal irrigation. Selection index5 which involved GY/P, 100GW and NG/S was the best index in improving GY/P.

Upland rice has diverse agro-ecological attributes that can tolerate changes brought by climate change. Hence, this study aimed to determine the performance of upland rice cultivars under rainfed lowland conditions, assess the root growth of upland rice cultivars under rainfed lowland conditions, and evaluate the profitability of growing upland rice cultivars under rainfed lowland ecosystems. This was laid out in a Randomized Complete Block Design (RCBD) with three replications. Twelve rice cultivars were designated as treatments, however, only seven rice cultivars survived namely; Caimpas, Black rice, Red rice, Speaker, NSIC Rc192, PSB Rc18, and NSIC Rc27 that showed significant differences on agronomic characteristics, root and shoot parameters, yield, yield components, and harvest index. The five drought-tolerant upland rice cultivars such as Perya, Remolites, Kalinayan Monos, Tukoran, and Lebolebo showed permanent wilting due to non-adjustment of said cultivars to changes in growing conditions from sufficient irrigation water during early growth to low soil moisture and absence of precipitation during the reproductive growth phase. Improved upland rice variety NSIC Rc27 performed excellently under limited soil moisture through early heading and maturity, and high grain yield as mainly contributed by its heavier straw yield, an abundant number of productive tillers, higher filled spikelets, the heavier weight of seeds, high harvest index and adjustment of aforesaid cultivar to drought. Thus generated the highest gross margin of 1,823.16.00 USD. Therefore, it is recommended to grow NSIC Rc27 under rainfed lowland ecosystems even if this cultivar is experiencing limitations on soil moisture conditions.

Two field trials were conducted at Mallawy Agric. Res., Station, El-Minia Governorate, Egypt, during 2017/2018
Two field trials were conducted at the experimental farm of Malawi Agricultural Research Station, El-Minia Governorate, Egypt, during 2018/2019 and 2019/2020 seasons to study the effect of three sowing dates (the 15th of September, October and November) under three irrigations number [eight, nine and seven irrigations] and their effects on root-rot disease, yield and quality of three sugar beet varieties (Farida, Panther and Gazil). A split -split plot design was used. The results indicated that sowing sugar beet on 15th Sept. significantly reduced root rot disease incidence and increased root traits (length, diameter and fresh weight), sucrose %, root and sugar yields/fed and recorded lower contents of impurities, compared to the others two sowing dates in both seasons. Sowing beet plants on 15th Nov. gave the highest phenolic compounds in both seasons. Decreasing irrigations number up to seven times significantly reduced disease severity% in both seasons. Irrigating sugar beet plants nine times significantly achieved the heavier roots and root yield compared to the other two irrigations in both seasons. Applying eight times of irrigation recorded the maximum phenolic compounds, sugar yield, and sucrose % compared to the less or a greater number of irrigations in both seasons. The combined analysis of variance and AMMI analysis of Farida cv. recorded the lowest response of root-rot severity % when applying seven times of irrigation at the first date of sowing (15th Sept.) and Ghazil cv. recorded the highest response to applying nine times of irrigation in the last date of sowing (15th Nov).

Two field experiments were conducted at Shandaweel Agricultural Research Station, Sohag Governorate, Egypt (latitude of 26 61° N, longitude of 31 52° E) in 2018/2019 and 2019/2020 seasons to assess the effect of number of irrigations on yield and quality of some sugarcane varieties. This work included 12 treatments, represent the combinations among (16, 18 and 20 irrigations/season) and sugarcane genotypes namely G.2004-27, G.2003-47, G.T.54-9 and 2005-47 genotype. A randomized complete block design was used in a split plot arrangement. Phenotypic, genotypic coefficient of variation and heritability% of growth, quality traits and yields of cane varieties were studied. Supplying sugarcane with 20 irrigations significantly increased number of millable canes, cane and sugar yields/fed sucrose% and sugar recovery%. Sugarcane varieties differed markedly in all studied traits. SugarcaneG.T.54-9 variety recorded the highest cane yield/fed, while G.2003-47 was superior in sucrose% and sugar recovery% and sugar yield/fed. Stalk height recorded the highest values of genotypic (σ2g) and phenotypic (σ2p) followed by cane yield/fed. Sugar recovery% recorded the highest values of GCV and PCV. Significant and positive correlation was found between cane yield, cane weight and number of millable canes. Sugar yield/fed was significantly and positively correlated with juice purity%, followed by sugar recovery%, then sucrose%. Planting the commercial variety viz. G.T.54-9 given 20 irrigations is preferable to get the highest cane yield/fed, without significant difference with G.2004-27 at 16 irrigations. Planting G.2003-47 supplied with 16 irrigations can be recommended for the highest sugar yield/fed, without variance with G.T.54-9 at 20 irrigations.

Fractionation and mobility of copper, cadmium, and lead in some soil irrigated with sewage water in Qena governorate, upper Egypt
H.M.
Farrag
This study was conducted to investigate the chemical fractionation and mobility of Cu, Cd and Pb in some soil irrigated with sewage water in Qena governorate, Upper Egypt. Sequential extraction results showed that in the treated soil, a major proportion of Cu, Pb, and Cd was associated with poorly crystalline iron oxide bound (PCFeOX), crystalline iron oxide – occluded (CFeOX) and a major proportion of Cu, Pb and Cd was associated with residual (RES) fractions. Based on relative percent. the results also show that The non-labile Cu, Cd and Pb in the non-irrigated soil partially transformed to the potentially labile Cu due to the irrigation with sewage water Also, a part of the readily labile and potentially labile Cu, Cd and Pb of the sewage water irrigated soils for short time transformed to the non-labile fraction with irrigation with same water for a long time. Higher mobility of metals in the soils irrigated with sewage water for short time represent a potential hazard for the redistribution and translocation of these metals into the food chain and leach to ground water.

improving seed yield in a segregating population of faba bean (Giza 429 × Triple white × Misr 1) × (ILB-938 × Nubariah 1 × Misr 1) in the F2- F5 generations. The experiments were conducted at South Valley University Experimental Farm, Qena, Egypt during growing seasons 2014/2015 to 2017/2018. Highly significant differences among the F5-selected families were observed for the selection criterion; seed yield/plant and all correlated traits either after three cycles of selection (pedigree method) or one cycle selection (bulk method). The genetic variability retained after bulk method was larger and more pronounced than that after pedigree method for the selection criterion; seed yield/plant. While, all studied correlated traits showed smaller genotypic variability after bulk method than that after pedigree method. After three cycles of selection, pedigree selection increased seed yield/plant by 21.82, 20.58 and 53.49% from the bulk sample, the best parent and the check cultivar, respectively. But, after one cycle of selection, bulk method increased seed yield/plant by 8.43, 7.27 and 38.24% from the bulk sample, the best parent and the check cultivar, respectively. Pedigree selection method for improving seed yield was more efficient compared to the bulk method in isolating high yielding genotypes. However, it was accompanied with favorable increased in no. of branches/plant, no. of pods/plant, no. of seeds/plant and 100-seed weight and undesirable delay in flowering date.

Eleven genotypes of sugarcane (ten genotypes and one commercial variety G.T.54-9 as a control) were evaluated at twelve environments; three locations (Agric. Res. Stations of Kom-Ombo, Aswan governorate, El-Mataana, Luxor governorate and Shandaweel, Sohag governorate and two harvesting dates; 11 and 12 month-old in 2015/2016 (plant-cane) and 2016/2017 (first-ratoon).The differences among genotypes, locations and between harvesting dates were significant for all studied traits; stalk length, stalk weight, cane yield, brix, sucrose and sugar yield. The interaction of locations × genotypes was highly significant in plant-cane and first-ratoon for all studied traits. Locations × harvesting dates interaction was significantly for stalk length in plant-cane crop and for stalk weight, sucrose and sugar yield in first-ratoon crop. Mean squares due to interaction between genotypes, harvesting dates and locations were significantly for all studied traits, except cane and sugar yields in plant-crop and stalk length in first-ratoon. Mean cane yield ranged from 54.23 and 52.61 to 57.61 and 56.71t/fed at harvesting dates and from 46.66 and 50.12 to 60.71 and 58.69 t/fed under locations in plant-cane and first-ratoon, respectively. Late harvesting date increased cane yield and its components. The stability analysis of variance for cane yield showed that the intermediate yielding genotypes (G.2003-47, G.2004-27 and G.2011-82) were more stable than the rather responsive high yielding ones. However, the genotype G. 2004-27 was stable for cane yield and its components. In addition, it was considered to be superior for cane yield under different environments. However, the highest yielding genotype (G.99-103) was unstable.

This study aimed to measure survivorship and fecundity of the vedalia beetle, Rodolia cardinalis (Mulsant) reared on three mealybug species (Icerya purchasi Maskell, Planococcus ficus (Signoret)and Pseudococcus longispinus (Targioni-Tozzetti)). The experiment was conducted under laboratory conditions, life table and population parameters were established to evaluate survivorship in all stages of the vedalia beetle life cycle. Results obtained from this experiment showed that the highest rates of death were recorded in the immature stages (larval stages) for all prey was 42.86, 45, 44.11 % and the total mortality was 57.69, 62.11, and 50 % on I. purchasi, P. ficus and P. longispinus respectively. Fertility tables recorded that the reproductive rate R0 of the population was 139.98, 81.10, 37.70 and mean generation time T was 35.85, 44.71, 44.03 and the intrinsic rate of increase r was 0.14, 0.09, 0.08 and the population doubling time DT was within 4.95, 6.93,8.66 day for three mealybug species respectively. Based on the mentioned results, it could be proved that the survivorship curve of Rodolia cardinalis (Mulsant)belongs to a diagonal model curve, which indicates a humble rate of death during life stages and piecemeal reduction when moving toward adulthood with a significant influence of nutrition preference for I. purchasi comparative with P. ficus and P. longispinus.

The experiment was conducted in the Agronomy Department, Faculty of Agriculture, Sohag University, Egypt in winter season of 2019/2020 to identify the most appropriate wheat genotypes to water stress. Ten bread wheat genotypes (3 Egyptian cultivars and 7 imported accessions (were screened under osmotic stress with three drought stress treatments induced by PEG-6000 (polyethylene glycol) i.e. control, 5% and 10% PEG-6000 solutions. The analysis of variance indicated significant differences among treatments for all recorded germination parameters (GP, GIT, GMT, GDT, SP, MDG, MTG, GC, GV and GVI). Where GP, SP, GC, GV and GVI were decreased under low water potential, while the drought stress caused retarding of germination process, continued in long period, acted in increasing of GIT, GMT, GDT, MDG and MTG.Significant interactions revealed that wheat genotypes responded variably to osmotic stress treatments. Hence, that is provided better opportunity to select drought tolerant cultivars at germination stage. Tow genotypes; G3 and G10 (Misr 1) were very good tolerant to drought stress at 5% PEG and ranked as 1st and 2nd order, respectively. They produced the highest germination vigor, so the seedling will be in regular growth. In the severe stress induced by 10% PEG treatment, the genotype G3 was more superior more than the others in all germination parameters. In the end we can recommend the genotypes G3 and G10 (Misr1) for drought stress conditions with modify their seeding rates ((100/GP in stress conditions) x optimal seeding rates).

Proper management of rice cultivation through the use of superior varieties and the application of a planting system adapted to site-specific conditions are very important in increasing rice yields. The purpose of this study was to determine and obtain the appropriate planting system to increase rice yield of superior varieties. The experiment adopted a split plot arranged in a randomized complete block design with two mainplot (planting systems) and three subplot (rice varieties) replicated four times. The mainplot was the planting system consisting of tile 20 cm × 20 cm and legowo 4:1 (20 cm–40 cm) × 10 cm, while the subplot was rice varieties consisting of Mira 1, Inpari 32, and Inpari 34. There was an interaction effect between the planting system and the rice varieties on grain yields. Legowo 4:1 planting system showed higher grain yield than the tile planting system on the three varieties tested for this experiment. The application of the legowo 4:1 planting system on Mira 1 obtained the highest grain yield of 5.65 t ha-1 or increased by 5.6% compared to the tile planting system. The Mira 1 was a superior rice variety that was suitable to be applied to the planting system of legowo 4:1 (20 cm–40 cm) × 10 cm to increase rice yield.

Combined effect of vital wheat gluten, ascorbic acid and emulsifier addition on the quality characteristics of whole grain barley bread.
M.H.
Abd-El-Khalek
There is a renewed attention in barley for being used in food products due to its nutritional benefits. Unfortunately barley breads are still inferior in their quality characteristics when compared to their wheat counterparts. The present work studied the individual and interactive effects of three bread improvers (i.e. vital wheat gluten VWG, ascorbic acid AA and sodium stearoyl-2-lactylate SSL) on the quality characteristics of wholegrain barley bread. Results showed significant effects of such improvers on both bread specific volume and overall sensory acceptability. VWG-AA and AA- SSL interactive effects were positively correlated with bread overall acceptability. Inclusion of bread improvers according to the obtained optimized formula showed a positive effect on bread with regard to its dough rheological properties (longer stability time, lower degree of softening and higher extensibility), physical (specific volume), textural (hardness and springiness), and crumb DIA characteristics of bread. Chemical analysis showed higher nutrient contents (protein, fiber and minerals) in the optimized barley bread when compared to their wheat counterparts. The overall sensory characteristics of the optimized barley bread were acceptable by the panelists with scores corresponded to “like moderately” compared to “extremely like/like very much” in case of wheat bread.

Nowadays, nanotechnology is more frequently used with the presence of new tools for utilizing nanoparticle-sized essential elements, enhancing the animal’s ability to absorb these elements and thereby improving their productive and reproductive performance. Zinc oxide nanoparticles (Nano-ZnO) can promote productive performance, act as antibacterial agents, and influence the immunity and reproduction of the rabbits. Moreover, zinc (Zn) increases semen volume, total live sperm concentration, percentage of sperm motility, and conception rate in heat-stressed rabbits. Several studies have already reported the effects of low and high zinc doses on rabbit performance. The most observed and analyzed reproductive performance variables are semen quality, spermatogonia, and meiosis of spermatocytes. Most of the studies showed slight positive effects; however, significant results were rare. Since there are almost unlimited possibilities regarding the zinc dosage, further research is still required. Nano-sized zinc particles can be used at low doses, resulting in better outcomes than conventional zinc sources. This review provides an overview of and illustrates the positive effects of zinc nanoparticles and their potential application as a mineral supplement to rabbit diets.

Sixty four genotypes (28 F1,s, 28 F2-populations and their 8 parents) were evaluated for days to heading, plant height, 100-grain weight and grain yield/plant under two sowing dates (Nov., 22nd , normal sowing date and Dec., 30th, late sowing date) in 2017/2018 growing season at the Exp. Farm of South Valley Uni., Qena, Egypt. The differences among parents, F1,s, F2-populations andparents vs crosses were highly significant at both planting dates for all studied traits. Delaying sowing date reduced performance all studied traits. The parents; P3, P4, P6 and P8 and the crosses; P1 × P3, P1 × P6, P1 × P8, P2 × P3, P2 × P5, and P3 × P8 displayed HSI and S less than one and they were relatively heat tolerant and less sensitive to heat of F1 and F2-generations. Highly significant differences due to general (GCA) and specific (SCA) combining abilities were detected for all studied traits. The ratio of GCA to SCA was less than one for all studied traits, indicating that the major effect in the control of these traits was by non-additive gene action, except plant height. The parent P3 was considered as the best combiner for heading, plant height and grain weight, but the parent P2 was considered as the best combiner of F1,s and F2-generations for 100-grain weight and grain yield/plant under both dates. The cross P2 × P8 could be considered as the best combination of F1,s and F2-generations for all studied traits under both planting dates.

Analysis in determining factors influencing rice farms productivity in Ebonyi State, Nigeria
O.N.
Cordelia
O.
Edwin
A great impediment to achieving food security in Nigeria is the low productivity of most staple food crops, which has translated to limited food availability for the populace. These have jeopardized the efforts made by the Nigerian government towards food security. Government emphasis geared towards improving input use, and development of improved seed varieties while the root causes of low productivity of staple foods are left unattended to. This research centered on analysis in determining factors influencing rice farms productivity in Ebonyi State, Nigeria. Four hundred and seventy-six (476) rice farms were selected through multi-stage sampling procedure. Primary data were collected using structured questionnaire, and analyzed using mean, percentage, Total Factor Productivity (TFP), and regression method. The result shows that extension visit, household size, and rice farm size had positive influence on rice farms productivity while age of the farmer and quantity of herbicide had a negative influence on rice farms productivity. Result further revealed that 1% increase in herbicide quantity, will decrease rice farm productivity by 4%. Agricultural Development Programme (ADP) and other non-governmental agencies that have the mandate of agricultural development in Nigeria, should intensify efforts in training rice farmers in better rice production practices with more emphasis on herbicide usage. In-depth soil analysis should be conducted in Ebonyi soil to ascertain herbicide compatibility with the soil.

Continuous extensive land use without proper land management has the potential to degrade the inherent soil fertility. Kwallatawa grazing lands are experiencing such exploitation which if not properly addressed, can dwindled their potentials. To address this, characterization and classification of the soils were carried out at reconnaissance level to assess the properties of the grazing soils. Two pedons were dug and described following FAO (2006) guidelines. The results show that pedons Gra P1 and P2 had shallow to slightly deep genetic horizons. They also show discernible colour pattern at both topsoil and subsoil layers. The pedons were sandy in texture with moderate bulk density (1.4 g Bd cm-3) and low (<50%) to high (>50%) porosity at surface and subsurface horizons respectively. Similarly, the soils were moderately acidic (5.81 mean), low in organic carbon (2.3 g C/kg mean), CEC (5.37 cmol+ CEC/kgmean) as well as high in total nitrogen (1.14 g N kg-1 mean), exchangeable sodium (>0.5 cmol+ Na kg-1) and percent base saturation (>80%). The Pedons Gra-P1 and P2 were respectively classified following USDA Soil Taxonomy as Typic Ustipsamments and Lithic Ustipsamments, and then subsequently correlated with WRB for Soils Classification as Eutric Arenosols (Arenic) and Plinthic Arenosols (Arenic). Our results revealed the soils to be acidic and fall within low to medium fertility class, as such liming and incorporation of organic residue were recommended to checkmate their deficiencies.

In this study, twenty fife bread wheat genotypes were tested under eight environments (2 growing seasons × 4 water stresses) on physiological and agronomic traits by using Eberhart and Russell (1966), Perkins and Jinks (1968) and Freeman and Perkins (1971) models to study stability and adaptability of the genotypes. Analysis of variance showed highly significant variations among the tested bread wheat genotypes for all studied traits. The results indicated that Line 9 (13.21 ardab/feddan) beside Sids 1 (13.19 ardab/feddan) and Misr 2 (11.91 ardab/feddan) cultivars were observed as most stable and widely adapted across environments, surprised mean performance for grain yield than grand mean, regression coefficient (biEberhart and biFreeman) equal or near to one, BiPerkins equal or near to zero and mean square deviation from regression (S2diEberhart and S2diFreeman) nonsignificant, according to previous models. Moreover, Line 9 showed also stability for number of spikes/plant, 1000 kernel weight and chlorophyll concentration under various environments, it was considered to be superior for grain yield across different environments. Meanwhile, the highest yielding genotype (Line 20) showed stability only under favorable conditions (surpassed the grand mean by 15.58 ardab/feddan, biE and biF > 1, Bi > 0 and S2diE and S2diF non-significant), it could be promoted to breeding program with a stable genotype (Line 9) over different environments to obtain a stable variety across environments with a high yield.

Abstract: Food insecurity is a long-term critical problem in Afghanistan. In 2019, the food and agricultural organization (FAO) noted that more than 53.2% of Afghanistan citizens were food insecure, and a total of 11million habitants need food aid. The main focus of this paper to understand food security variation, mainly where and under what natural and socio-economic situations Afghanistan citizens become susceptible food insecurity. This article provides an overview of food security in Afghanistan with respect to the four principal components of food security, namely food availability, food access, food utilization, and food stability. It identifies the knowledge gaps in these four pillars of food security assessment and makes recommendations to advance the research policy linkage in Afghanistan Agriculture sector. This study also highlights Afghanistan's current food production capabilities and the impact of social-economic factors on the four pillars of food security and suggests different procedures and policies improve it. In conclusion, this study provides a foundation for policy development to advance understanding and qualitative discourse to improve Afghanistan's food security situation.

Bombyx mori L. is one of the most economically important insects because of its production of silk. In this study, we investigated the effect of four plants powder mix on larvae weight, silk gland weight, cocoon parameters and fecundity of moths in two hybrids (local and imported) of silkworm. The most desirable effects (increased final larvae weight by over 8.93%, silk gland weight by over 37.45%, cocoon shell weight by over 39.84% and No. of eggs by over 28.93%) was obtained by treatment of mulberry leaves with (M2) in local hybrid. Meanwhile in imported hybrid the most desirable effects (increased final larvae weight by over 3.75%, silk gland weight by over 51.29%. cocoon shell weight by over 22.17% and No. of eggs by over 55.87%) was got by treatment of mulberry leaves with (M3) and feed it to the larvae. According to the results, It can enrich the nutrient quality of mulberry leaves provided to the silkworm by adding such plant materials, which lead to raising the efficiency of larvae productivity, increasing the quantity and quality of cocoons, and then improving the production of silk.

The present work relates to estimate the effect of magnetically-treated saline water on physiological and agronomic traits of 22 bread wheat genotypes and to determine the changes in soil properties. Replicated pot experiments involving potable water, saline water (2500 and 5000 ppm) and magnetically treated (2500 and 5000 ppm saline water) were conducted in greenhouse during 2017/2018 and 2018/2019 winter seasons at Faculty of Agriculture, Sohag University, Sohag, Egypt. The results showed the magnetically treated 2500 and 5000 ppm saline water had positive effects on chlorophyll concentration by 7.29% and 7.96% and canopy temperature by -6.14 % and -3.93% when compared with 2500 and 5000 ppm saline water, respectively. Moreover, the percent of increase due to using 2500 and 5000 ppm saline water treated with magnetic reached to 4.25 and 8.42% for plant height, 3.7 and 13.43% for number of spikes/plant, 1.43 and 4.09% for spike length, 15.42 and 16.55% for 100 kernel weight, 6.52 and 6.15% for biological yield/plant and 9.94 and 5.41% for grain yield/plant compared to irrigation with 2500 and 5000 ppm saline water, respectively. Also, the mean values of soil soluble cations and anions were less in soil irrigated with treated magnetic water than that irrigated with untreated magnetic water (having salinity of 2500 and 5000 ppm). It could be that the treated magnetic water could effectively increase the physiological and agronomic traits. But indeed, more studies are needed to declare the influence of magnetic water on the growth, yield and quality of other different crops.

M.A.M.
Osman
Sugarcane mosaic virus(SCMV) is one among many viruses that infects sugarcane; causes yield loss and becomes serious disease on sugarcane plantations. This research aimed to survey it on commercial sugarcane varieties G.T. 54-9 in 19 locations of Esna district Luxor governorate during 2018/19 on 4 ages and effect of infection with virus on growth, juice quality and yield components of two sugarcane varieties viz., G. T. 54-9 and G. 2017-57 at El-Mattana Research Station, Luxor Governorate during 2018/19 and 2019/20 seasons. Mosaic symptomatic plants were observed in nineteen production areas, with incidences ranging from 0 to 93.33%. The spatial pattern and geographical distribution of disease incidence suggested that infected seed cane was the main source to spread of the disease. Surveyed results revealed that disease incidence was varied between surveyed locations. Plant cane was lower than first and second ratoons in all fields. Locations i.e. El-trakee (Awladhamid) (EN4), Elfarsea (30-115 El-motawlelgrby) (EN7), El-Dkera (Mohamed Hassan) (EN18) and El-Adima (Abd-elrahman) (EN19 were free infection from such disease. The results revealed that a significant reduction in number of millable cane/m2, stalk diameter (cm.), stalk length (cm.) and number of internodes/plant in G. T. 54-9 and G. 2017-57 varieties due to virus infection. On the other hand, infection of two tested sugarcane varieties with SCMV caused significant reduction in juice extraction (kg), brix (TSS) %, purity%, pol% and sugar recovery%. It significantly increased of sucrose% and reducing sugars% in two tested varieties in two tested seasons also infection with virus caused significant decreased in cane yield (tons/fed.) and sugar yield (tons/fed.)

The biology, life table parameters and predation efficiency of the predatory mite, Euseius scutalis (Acari: Phytoseiidae) feed Tenuipalpus punicae mobile stages and Siphoninus phillyreae eggs were tested at constant conditions (30 ± 1ºC & 65 ± 5 % R.H.). The predator completed its developmental times on both prey pests in 6.20 and 6.45 days. The mite was slightly influenced by the prey type, as when fed T. punicae mobile stages, its developmental time were shorter than preyed on S. phillyreae eggs. Whenever, the female predator fed the mite mobile stages, the finite rate of increase (λ) was higher than that on the insect eggs. The mean generation time (T) was also affected, whereas it was longer when the female preyed on S. phillyreae eggs compared with that on T. punicae mobile stages. The E. scutalis female consumed high number of insecteggs during its oviposition period and the longevity was longer in comparison with feed T. punicae mobile stages.

This study was conducted at Kom-Mombo Agricultural Research Station, Aswan governorate, ARC, Egypt to study the performance and stability analysis of some wheat genotypes.Twelve genotypes of bread wheat were investigated under six environments; two years (2016/2017 and 2017/2018 seasons) and three sowing dates (normal (D1), 23rd of Nov., late (D2), 13th of Dec. and very late (D3), 16th of January). The differences among years, dates and genotypes were significant (p ˂ 0.01) for heading date, plant height, 100-grain weight and grain yield. All first order interactionswere significant for most studied traits. Mean squares due to interaction between genotypes, sowing dates and years were significantly for heading date and grain yield. The early sowing outyielded late and vey late one by 17.79 and 63.50%, respectively. Delaying sowing date reduced all traits under investigated. Five genotypes were less susceptible (heat susceptibility index less than one) and less sensitive (less than one) for heat stress.The stability analysis for grain yield exhibited that the intermediate yielding genotypes (Masr 1, Masr 2, Sids 12, Sids 13, Sids 14, BAG#1 and KACHU*2)were stableand ranged in yield from 8.90 to 12.28Ard/fed.). However, the genotype Masr 1 was stable and high in grain yield. While, the highest yielding genotype; Gimmiza 11 was unstable.

This research was undertaken to investigate 28 genotypes (21 F1-crosses and their seven parents) for heading date, plant height, 100-grain weight, and grain yield plant-1under two planting dates (November 21st as regular planting date and 21st of December as late planting date) at El-Mattana, Agricultural Research Station, Luxor governorate, ARC, in2017/2018 and 2018/2019 growing seasons. Highly significant differences among genotypes, parents, crosses, and parents vs. crosses for all traits investigated under both sowing dates. Heat stress reduced estimates of all studied traits. Three parents (P1, P6,and P7) and seven F1-hybrids (P1 × P2, P1 × P3, P1 × P5, P1 × P7, P4× P7, P5 × P6, and P6 × P7) were highly tolerant, less susceptible (heat susceptibility index less than one), and less sensitive (less than one) for heat stress. Mean squares due to general (GCA) and specific (SCA) combining ability were highly significant for all studied traits. GCA/SCA ratios' magnitude were lower than one for all studied traits under both planting dates. The parents P5 and P7 were having significant adverse GCA effects for heading date, and the parents P2 and P4 showed significant positive effects for plant height and grain yield. The hybrid P2 × P7 observed significant positive heterosis in grain yield, 100-grain weight, and plant height, however, significantly negative in heading date in addition to satisfactory performance.

The study aimed to investigate the effect of light source on growth performance and physiological response of broilers. A total number of one hundred and ninety-two unsexed seven-day old; Cobb broiler chicks were used in this study. Chicks were allocated into two treatment groups. Each treatment consisted of twelve replicates eight birds each. Birds in treatment 1 were exposed to yellow-reddish light produced from 60-watt incandescent lamps, while those in treatment 2 were subjected to white light by using 26 watt saving lamps. The light intensity for all experimental birds were 5 lux at the level of a bird till the end of experiment. Results showed that, using 26 watt saving lamps significantly increased body weight and body weight gain at 28, 35 and 42 days of age, feed consumption at 42 days of age and improved feed conversion ratio from 21-28 and 7-42 days of age. Moreover, using saving lamps significantly increased glucose, HDL and uric acid concentrations and significantly reduced all of creatinine, triglyceride and VLDL. It could be concluded that the using saving lamps as lighting source is more beneficial than the yellow-reddish light produced from 60-watt incandescent lamps

Bio-stimulants play a vital role in the sustainable development of horticultural crops. The aim of this study was to assess the effect of synthesis stimulator (salicylic acid) and bio-stimulants (moringa extract, seaweed extract) on growth, yield and quality of Roselle, Hibiscus sabdariffa L., plants. The recorded growth parameter included plant height, number of lateral branches per plant, branch diameter, and leaf area. For yield traits, the calyxes' fresh and dry weight was recorded. Leaf pigments included chlorophyll a, b, and carotenoids. Anthocyanin content in calyxes was measured. The experiment was conducted during 2018 and 2019 seasons, and was designed in completely randomized system. The results showed that application of bio-stimulants showed positive effects on all traits, and the best results were shown under treatment of seaweed, followed by moringa leaves extract. There were positively associations of calyxes yield and its anthocyanin content with other growth traits and photosynthetic pigments. These results highlighted the important role of bio-stimulants, especially seaweed extract, as a bioactive stimulant. Therefore, it is recommended to include seaweed extract in fertilization programs for achieving sustainable production system of such crops.

The present study was conducted to selecting wheat stable cultivars with high productivity across various environments using the models of Eberhart & Russell (1966) and Tai (1971). Fife wheat cultivars viz, Shandwell 1, Sids 1, Sids 12, Giza 168 and Misr 2 were grown in a randomized complete block design with four replications under sixteen environmental conditions (2 years x 2 locations x 4 sowing dates) on yield and yield components during two successive seasons of 2017/2018 and 2018/2019. Pooled analysis of variance for grain yield and its components revealed significant variance due to genotypes, environments, and their interactions, indicating that they varied in their responses to diverse environments. Highest significant grain yield across varied environments was found by Sids 12 (14.60 ardab/feddan) followed by Shandwell 1 (13.61 ardab/feddan). The results indicated that according to Eberhart & Russell and Tai, the cultivar Shandwell 1 was genetically stable across various environments because it showed high mean performance for grain yield over these environments when compared with grand mean beside acceptable stability parameters (bi near to one, S2di non-significant, α stability value not significantly differed from zero and the λ statistic was not significantly differed from one, also it appeared stable over environments for other traits according to both previous methods. Meanwhile, cultivar Sids 12 were stable over all the studied environments for grain yield, but only according to Eberhart & Russell method.

Artemisia annua is a medicinal plant that produce artemisinin, which has antimalarial activity. Artemisinin biosynthesis pathway depends on number of genes such as ADS, CPR and CYP71AV1. we studied gene structure of three genes which exhibit ADS gene possess 4 introns and 5 Exons with length 1794bp, CPR has to analyze the sequences of these genes, the CPR gene contains 6 introns and 7 exons with length 1633bp and CYP71AV1gene has 1 intron and 2 Exons with length 1554bp. Cis-acting elements detection in ADS, CPR and CYP71AV1 promoters revealed several such W-box , WRKY , TATA-BOX,CAAT-BOX ,IBOX MYC ,EBOX,GATA-BOX, which could be involved in gene expression regulation of artemisinin production genes. Our genes could be influenced by different external affects as light, cold, drought and elicitors which in turn may be due to an effect on the amount of artemisinin produced. ADS, CPR and CYP71AV1 proteins evolution shows Artemisia annua, and Tanacetum cinerariifolium always are closed in one cluster which refers to a common ancestor of those two genotypes.

This study aimed to determine the growth and yield performance of five rice varieties under the different crop establishments and assess rice profitability as influenced by crop establishment under irrigated lowland conditions. The study was laid out in a split-plot arranged in an RCBD with three replications. Crop establishment was designated as the main plot while rice varieties as a subplot. Results revealed that the direct row seeding method significantly showed a significant advantage in agronomic and yield and yield component parameters over the transplanting method among rice varieties tested. Heirloom red rice significantly headed earlier (63.17 days) when planted in both crop establishments and obtained the tallest plant height, greater leaf area index, the heavier weight of 1,000 grains, and grain yield. There was a significant interaction effect on crop establishment and rice variety recorded from sowing to heading and maturity. Cost and return analysis revealed that the direct row seeding method achieved higher gross income (USD 2,012.00) and gross margin (USD 1,086.60) than the transplanting method. Heirloom red rice significantly achieved the highest grain yield (5.85 t ha-1), resulting in a higher gross income and gross margin of USD 2,340.00 and USD 1,352.45, respectively. Direct row seeding is applicable as an effective cost-reducing method of crop establishment for lowland rice production. Besides, it can shorten the time of crop establishment. Heirloom red rice with dual characteristics as an irrigated lowland and upland rice cultivar is feasible for direct row seeding and transplanting methods during the dry season.
