| Abstract | ||||
| The objective of this study was to investigate the influence of spraying with magnesium [0, 100 and 150 ppm] and potassium fertilization rates (35, 50 and 65 kg K2O /fad.) on Vicia faba,L yield and seeds quality. Two field trials were carried out at the Experimental Farm of Agricultural Res., Center, Al-Azhar University, Assuit Governorate, Egypt during two successive seasons of 2016/2017 and 2017/2018 using faba bean cultivar Giza-843. Split plot design was used with three replicates; where potassium fertilization rates were assigned to the main plot, while spraying with magnesium were distributed randomly in the sub plot. Results revealed that the mean values of no. of branches/plant, no. of pods/plant, 100-seed weight, seed and straw yields/fad. and protein percentage of seeds were increased significantly with increasing rates of potassium fertilizers. The highest values were recorded with using 65 kg K2O / fed. Magnesium spraying with increasing application concentration increased from 0, 100 to 150 ppm had significant increased in all studied characters in both season. The interaction between of potassium fertilization and magnesium spraying improved yield and yield components, of faba bean. Therefore, this study recommends that adding potassium fertilization at the rate of 65 kg K2O/fad., and spraying with magnesium (150 ppm) in order to improve the production of faba bean under the conditions of Assiut Governorate, Egypt. | ||||
