Agronomical and nutritional responses of some faba bean (Vicia faba L.) genotypes to organic fertilizations under sandy soil conditions

Formulating applied of vermicompost in combination with plant and animal compost as a plant nutrient, to improve the performances of faba bean cultivars in reclaiming areas. In this present study, agronomical and nutritional quality of some faba bean genotypes were evaluated as response to organic fertilizations under sandy soil conditions. Two field trials in this investigation were carried out under a drip irrigation system in the Desert Experimental Station, Faculty of Agriculture, Cairo University in Wadi El-Natroon, El-Beheira Governorate, Egypt, during two winter seasons, 2018/2019 and 2019 /2020. A split-plot design in randomized complete blocks arrangement, with four replications accordingly to the studied two factors. Main plots were devoted to three cultivars, and sub-plots were allocated to nine treatments. The results indicated that both the two-factor cultivars and treatments of organic fertilizers showed highly significant mean squares effects for all studied traits. The response of faba bean cultivars to plant compost plus vermicompost activated the highest yield and its components as compared to all other treatments. The application of organic amendments achieved the highest values of seed chemical contents. The response of Sakha-1 cultivar to 100 % plant compost attained the highest response of yield, crude protein, ether extract, and amino acid contents. Remarkably, the interaction between Sakha-1 cultivar and 100 % plant compost plus vermicompost achieved the optimal combination, leading to the highest seed yield (3.12 tons/ha). This combination is recommended in order to improve faba bean yield and nutritional quality of seeds under sandy soil conditions
