The Response of the Broad bean crop (Vicia faba L.) to phosphate and potassium fertilization and their Effect on the growth and yield characteristics

Abstract

The study for this research was carried out in Al-Alam district - Salah El-Din Governorate to study the effect of phosphate and potassium fertilizers on the growth and yield of (local) beans for the winter agricultural season 2019-2020. The experiment was implemented according to a R.CBD Randomized Complete Block Design with split plot system, using four phosphate levels (0, 65, 80 and 100 kg P.      h^-1) and four levels of potassium (0, 75, 90 and 105 kg K. h^-1). The best significant superiority was recorded at the level of 100 kg P. h^-1, an interference with 105 kg K. h^-1 in most traits, as it was recorded (98.60 cm) for plant height, (58.92%) for chlorophyll, (11.85 pods. Plant ^-1) for the number of pods, (190.33 g) For the weight of 100 seeds, (3.50 tons. h^-1) the seeds yield and (29.31%) for protein. As for the number of branches and the dry weight of the shoots, the level of 100 kg P. h^-1 by an interference with 90 kg, K. h^-1, the highest average was (10.76 branches. Plant^-1 and 14.64 g) respectively. We conclude from this study that the best interaction combination is between the levels of 100 kg P h^-1 and 105 kg K. h^-1 in most of the studied traits. The aim of this study is to determine the best fertilizer level of phosphate and potassium to improve the growth and yield traits of the beans plants and the extent to which the crop benefits from this addition.
