Limited freshwater resources and climatic change are major challenge face animal production industry, especially in the arid and semiarid regions. Climate changes are reflected in global warming and rainfall reduction, which in turn may increase the salinity of both soil and water. Within the reclamation strategy, groundwater will be the main source of used water in cultivated desert lands in Egypt. However, the groundwater has high salinity and the cost of desalination is expensive. This review gives an overview of the impact of using saline water as an alternative source of fresh water to avoid water scarcity effect on the performance, carcass traits, and meat quality of farm animals. The ability of animals to tolerate saline water depends on the animal species, salinity level and the type of salt minerals in water. Some studies indicated that the animals' performance improved in low levels of salinity, but the performance decreased when the salinity levels was increased. In conclusion, this study implies that the saline water containing high concentrations of minerals mainly sodium chloride can largely affect the livestock productive aspects.

The tomato borer, Tuta absoluta (Meyrick) is considered a devastating pest, particularly to the tomato Lycopersicon esculentum. The present study was carried out to determine the efficacy of five pesticides namely, indoxacarb, (abamectin+ thiamethoxam), emamectin benzoate, fipronil and imidacloprid against the 3rd larval instar of T. absoluta under laboratory conditions using the Leaf-dip method. The tested pesticides could be descendingly arranged as follows: emamectin benzoate, fipronil, (abamectin + thiamethoxam), indoxacarb and imidacloprid. The corresponding LC50 values after 72 h. were 0.07, 0.22, 0.28, 0.59 and 2.67 ppm, while LC90 values were 0.56, 3.25, 1.99, 4.69 and 30.29 ppm, respectively. It is clear that emamectin benzoate was the most toxic compound, whereas imidacloprid was the least toxic one. Results indicated that emamectin benzoate can be used as a good element in integrated management program to this pest.

The present study was carried out in the Agriculture Experimental of Shandaweel Agriculture Research Station, Sohag Governorate during two successive seasons of 2015/2016 and 2016/2017. Results of both seasons showed the population fluctuation of S. graminum. The obtained results revealed that greenbug increased from 0.60, 0.63 nymphs/tiller on 3rd, 4th week of January respectively, to reach a peak of 82.80, 66.40 nymphs/tiller in 2nd,3rd week of March respectively. Aptera of S. graminum started to appear in 4th week of January and increased to reach a maximum of 11.00, 4.7 individuals/tiller on both seasons respectively. The peak of alatae reached 3.90, 4.70 individuals/tiller respectively, in the 4th week of March. The population of all morphs started declining in the last week of March from field and disappeared by 1st week of April. The grubs and adults of Coccinella septempunctata Linné appeared on the crop during the beginning of February and their population increased with the increase in aphid population. Its abundance was maximum on the 4th week of March with average of 7.80, 9.06 individuals/tiller on both seasons respectively. The population of aphids had significant positive correlation with maximum, minimum, mean temperature were 0.6524, 0.481, 0.542 in first season and 0.5687,0.472, 0.364 in the second season respectively. But it showed negative correlation with humidity in both seasons -0.454, -0.391 respectively. The studies evaluate in detail the abiotic and biotic factors regulating the wheat aphid populations.

This study was conducted during two successive seasons 2017 and 2018 to study the effect of some oils immersing on the storability and quality of Balady mandarin (Citrus reticulate L.) fruits during the storage period. The post-harvest treatments were immersed with camphor oil, linen oil and imazalil either singly or in combination. The fruits were stored at cold condition 8±1°C with 85-90% RH. Samples of each treatment were randomly withdrawn monthly for 4 months. The results showed that fruit weight loss %, fruit decay %, total soluble solids %, sugar contents and TSS/acid ratio were significantly increased with prolonging the storage period. On other hand, the advanced storage period induced a gradual decrease of fruit juice percentage, fruits firmness, acidity % and vitamin C. All treatments caused a decrease in fruit weight and fruit decay percentage, fruits firmness, acidity % and vitamin C. Using oils resulted in the least fruit weight loss, whereas, imazalil treatment had the least fruit decay percentage. Also, all treatments improved the fruit quality during the storage period compared control. It could be concluded that oils plus imazalil coating maintained fruit freshness without negative effects of fruit quality parameters and seems to be the proper and ideal treatment to prolong cold storage of Balady mandarin fruits without great reduction in fruit quality.

This study was carried out at the tissue culture lab, Horticulture Department, Faculty of Agriculture, Minia University, Minia, Egypt. under in vitro condition to screening the response of four potato varieties (Diamond; Burren; Maritiema and Lady Balfour) to water stress induced by adding sorbitol in the culture medium. Four concentrations of sorbitol (0.0, 0.1, 0.2 and 0.3 mole /liter), in Murashige-Skoog (MS) medium were used for exerting the water deficiency stress on the plantlets with three replications, in completely randomized design. Data revealed that the potato cultivars were significant differed for plantlet height, number of leaves per plantlet, number of nodes per plantlet, number of roots per plantlet and plantlet weight in the medium without sorbitol. Moreover, different response of potato cultivars was observed to various levels of sorbitol concentrations. Increasing the concentration of sorbitol lead to significant decreased in all studied traits, as compared with control treatment (sorbitol free). However, the most reduction of morphological parameters was observed in Maritiema and Lady Balfour cultivars, and considered as susceptible cultivars for water deficit. These results indicated also that the Diamond variety is a drought-tolerant than the other potato cultivars which used in the current study. These results indicated that the simulation of drought stress under in vitro conditions during the regeneration process constitutes a convenient way to study the effects of drought on potato responses. In-vitro this technique was shown to be useful in identifying relatively drought-tolerant genotypes at early stages of development and this can be a very useful tool for screening large number of varieties or breeding lines of genotypes within a short time.

The effect of high and low temperature and microwave radiation on the adult of the lesser grain borer, Rhyzopertha dominica (F.) infested wheat seeds was studied. At high temperature (55°C), 29% of the death occurred after 30 minutes and the complete death occurred after 60 minutes. The lethal time of 50% mortality (LT50) and lethal time of 90% mortality (LT90) values were 36.96 and 63.4 minutes. Cold temperature (-7°C) caused 12% mortality after 20 minutes and complete succumb was obtained after 75 minutes. The LT50 and LT90 values were 38.6 and 71.3 minutes. Microwave at power of 2450 MHZ caused 33% mortality after 10 seconds and 100% mortality after 35 seconds. The LT50 and LT90 values on this power were 12.8 and 26.3 seconds. The mean germination rate of wheat seeds was 5% for microwave treatment (2450 MHZ, 30 seconds). However, 70% germination rate was achieved when the seeds were exposed to low temperature (-7°C, 3 months), and 77.5% when high temperature (55°C, 60 minutes) were used. In conclusion, the present study showed that, cold temperature (-7°c), high temperature (55°c), and microwave radiation had been successfully controlled R. dominica in a short period of time, however, microwave radiation had adverse effects on the germination of wheat seeds. Radiation seeds should therefore not be used in planting.

Experiments were conducted during four consecutive seasons of 2017, 2018, 2019 and 2020 on three grape cultivars including “Bez-El-Anza”, “Thompson Seedless” and “Red Roomy” planted at the Experimental Orchard of fruit section, Faculty of Agriculture, Assiut University in a complete randomized blocked design. This investigation was carried out to study the effect of spraying Seaweed extract, Amino acids and Vitamins on C/N ratio, yield and berry quality of some grape cultivars. The obtained results showed that Tyrosin at 500 ppm recorded the highest yield (9.47 kg/vine) during the 1st season. All treatments had a significant impact in the respect of TSS %, acidity% and TSS/acid ratio. Concerning C/N ratio, Vit.B12 at 150 ppm recorded the highest ratio (44.85) during the 1st season. Hence, the present study concluded applications of Seaweed extract, amino acid and Vitamins improved vine C/N ratio, yield and berry attributes of “Bez-El-Anza”, ‘Thompson Seedless’ and “Red Roomy” grape cultivars.

The objective of this work was to study the effect of Doum (Hyphaenethebaica) supplementation on productive and reproductive performance of rabbit does in Upper Egypt during spring season. A total of 6 months old 160 does including 80 California (CAL) and 80 Newzland (NEZ) rabbits with average initial body weight 3.150±0.05 kg was randomly divided into four groups of 20 does each/breed (CAL or NEZ). The study was conducted in a 4×2 factorial design. Doum in the basal diet was supplemented for each strain with 4 levels 0, 0.3, 0.6, 0.9 g doum kg diet and offered to 2 rabbit breeds New Zealand White (NZW) and Californian (CAL) in upper Egypt. Doum in the basal diet was improved performances of rabbits compared to control. California does show significant higher productive and reproductive performances and lower mortality rate compared to the NEZ breed.

Acetone and petroleum ether seed extracts of fennel [Foeniclum vulgare, Apiaceae] and arugula seeds [Eruca vesicaria, Brassicaceae] were tested for their contact and stomach poison activity on adults the granary weevil Sitophilus granarius Linnaeus. (Coleoptera: Curculionidae) and lesser grain borer Rhyzopertha dominica Fabricius. (Coleoptera: Bostrochidae). The results revealed that, percentage of mortality increased with increasing the concentration of different extracts and exposure time. Extracts of arugula seeds of petroleum ether and acetone gave higher mortality percent compared with the extracts from fennel seeds. Petroleum ether and acetone extract of arugula seeds was founded to be the higher effect on the two species insect than the fennel seeds extracts. The LC50 of arugula seed extracts of petroleum ether and acetone ranged from 0.722, 0.620, 0.622 and 0.475 ml/ kg after 5 days treatment against R. dominica and S. granarius, respectively. On the other hand, these values of fennel seeds extract ranged from 1.331, 0.798, 1.093 and 0.662 for R. dominica and S. granarius, Respectively. While the higher concentration 1.5 and 2 % (W/V) give complete mortality at two extracts against two insects. The petroleum ether of fennel seeds extract with R. dominica give 73.3 and 83.3 % after 14 days treatment. The inhibition rates in the reduction of the first generation (F1-progeny) of R. dominica and S. granarius adults in grains treated with various extracts were higher than mortality at all concentrations to all extract.
