One of the major physiological disorders for pomegranate cultivation is the excessive of fruit cracking. lately, a pomegranate physiological syndrome called ‘aril paleness’ in which a part or all of the arils appear discoloration, affect the quality of fruit and such fruits are not desired for consumer. The present research designed to evaluate the effects of methyl jasmonate (MJ), humic acid (HA) and potassium (K) on reducing these disorders and improving fruit quality. Seven treatments including MJ (5 and 10 ppm), HA (50 and 100 ppm), Liquid K (1 and 2%) and control, were tested on pomegranate trees spraying three times, at the beginning of flowering (during April), after full bloom (end of June) and before harvesting (mid-September), during the two seasons of study. Different parameters including yield, fruit cracking and fruit quality were measured. The obtained results indicated that spraying HA at 100 ppm and MJ at 10 ppm are considered the best in their effects on the yield components, fruit quality and anthocyanin content, however for decreasing the fruit cracking, it could be recommended to spray the fruits with K at 1% or MJ 10 ppm compared to the rest of the treatments.South Valley University, Faculty of AgricultureSVU-International Journal of Agricultural Sciences2636-38013120210101Biological reclamation of a calcareous sandy soil with improving wheat growth using farmyard manure, acid producing bacteria and yeast537114592110.21608/svuijas.2021.57919.1070ENH.M.FarragSoil and water Department, Faculty of Agriculture, South Valley University, Egypt0000-0002-3734-9156Abeer A.BakrSoil and water Department, Faculty of Agriculture, South Valley University, EgyptJournal Article20210113Two pot experiments were performed in the Experimental Farm, Soils and Water Department, South Valley University, Qena, Egypt during two successive winter seasons (2018/2019 and 2019/2020). The main objective is to evaluate the effect of four addition levels of farmyard manure (FYM) (0, 10, 20 and 30 g/Kg of soil) combined with acid producing bacteria (APB) + molasses, yeast + molasses or their mixture on improving the chemical properties of a calcareous sandy soils and enhancing wheat growth. The results showed that, the results showed that with the increasing added level of FYM the soil pH and CaCO3 content were decreased and the soil EC, OM, total N and available P and K were increased. In addition, plant dry matter, N, P and K uptakes and use efficiencies were increased.

The objective of this experiment was to estimate the G×E interaction in sugar beet varieties of stability and adaptability through different environments using the AMMI model. As well as cluster analysis was automated to identify the interrelationships among the tested varieties, also Principal component analysis (PCA) was used to define the relationship between the studied traits. Twenty genotypes of sugar beet were evaluated at two locations (El- Dakahlia and El- Fayoum stations) in Egypt in two seasons (2018/19 and 2019/20). A randomized complete block design with three replications was used in each environment. Results showed that the AMMI analysis of variance was highly significant differences for the environment, variety and their interactions. Based on AMMI model, Glorius, Florima, Capel, Belatos, Classic and Toro genotypes in EN3 (Dakahlia 2019/2020), have the highest sugar yield, respectively. Results of cluster analysis demonstrated an extensive genetic diversity among the tested varieties, also the 1st sub cluster, (cluster I) was recorded high values of root weight, length, diameter and total weight. cluster II (Farida, TORO, Capel, Florima, Betamax, Glorius ) recorded the highest root and sugar yield, which led to increase of 106.66% and 112.91% higher than that compared with cluster V (Lilly, Heba, Mirador). According to PCA results, PCA1 accounted for 69.5% of the total phenotypic variation expressed and PCA2 accounted for 27.03% of the variation.South Valley University, Faculty of AgricultureSVU-International Journal of Agricultural Sciences2636-38013120210101The Sources of Microfinance Capital and its Effects on Farmers access to Credit in Ghana11212815794710.21608/svuijas.2021.61143.1080ENI.AnaneAgricultural Information Institute of Chinese Academy of Agricultural Sciences, Beijing 100081, ChinaY.ZhangCollege of Economics and Management, China Agricultural University Haidian District, Beijing, ChinaF.NieAgricultural Information Institute of Chinese Academy of Agricultural Sciences, Beijing 100081, ChinaJournal Article20210203Farmers in Ghana face difficulties in accessing microfinance credit, and as a result, there is low accessibility to microfinance credit. This study explores the effects of sources of microfinance capital on farmers’ access to credit. A total of 2734 individual household members were used in the final analysis to establish the relationship between the sources of microfinance capital and farmers’ access to microfinance credit. The participants include clients of selected microfinance institutions and non-client households. Logistic regression models were employed for data analyses. The study has shown that microfinance capital’s source significantly influences farmers’ access to credit. The analysis further revealed that land ownership, gender, and literacy strongly correlate with farmers’ access to credit. The study has also established that savings account, microfinance membership, and geographical location significantly influence the credit providers’ decision-making process to grant a loan to the customer. Our findings suggest that microfinance institutions have not been able to perform their business effectively because of capitalization. Sensitization programs are needed to enable microfinance institutions to configure innovative financing methods to improve capitalization. There is a need to improve the sources of funds and capital mobilization to maximize their financial performance and increase farmers’ access to credit. Education to farmers to understand credit providers’ requirements can also increase farmers’ access to microfinance credit.South Valley University, Faculty of AgricultureSVU-International Journal of Agricultural Sciences2636-38013120210101Evaluation of some new somaclones of sugarcane for yield and quality12913915740110.21608/svuijas.2021.59073.1073ENA.Abo-ElwafaDepartment of Agronomy, Faculty of Agriculture, Assiut University, EgyptB.R.BakheitDepartment of Agronomy, Faculty of Agriculture, Assiut University, EgyptA.M.El-TaibDepartment of Agronomy, Faculty of Agriculture and Natural Resources, Aswan University, EgyptN.Y.NobyDepartment of Agronomy, Faculty of Agriculture and Natural Resources, Aswan University, EgyptJournal Article20210120The study aims to determine the genetic variability among eleven somaclones of sugarcane obtained via immature leaves of the Egyptian commercial variety GT-54 9 at Agronomy Department, Faculty of Agriculture, Assiut University. Significant differences were found among the somaclones and also their donor, revealing to abundance genetic differences among them. The highest values of GCV and PCV were estimated in agronomic traits for cane yield (18.11 and 18.53%) and in technological traits for sugar yield (17.65 and 17.76%) over two ratoon crops, respectively. The heritability in agronomic traits ranged from 50.39 (stalk diameter) to 98.46% (cane yield) and in technological traits varied from 73.02 (purity) to 98.78% (sugar yield) over the both ratoon crops. The obtained significant differences coupled with GCV, PCV and heritability estimates explained the differences among the studied somaclones (somaclonal variation). The average over the two ratoon crops revealed that somaclones no. 7 and 8 surpassed the donor in highly significant values for most agronomic traits <em>i.e.</em> stalk height (14.35 and 9.48%), stalk weight (9.52 and 15.24%), stalk number/fed (21.00 and 31.25%) and cane yield (32.16 and 52.02%), respectively. Also, the somaclone no. 4 surpassed the donor in highly significant values for all technological traits <em>i.e.</em> sugar yield (23.52), brix (3.13), sucrose% (6.28), purity% (2.99), pol% (6.36) and sugar recovery% (7.72%). The results concluded that the <em>In-vitro</em> cultures exhibited genetic variability among the obtained somaclones (somaclonal variation), which could be used to invent new superior somaclones and overcome the accomplishments of traditional cane breeding.
