ABSTRACT
The experimental field is located bean
crop is cultivated in winter season 2019.The objective of this work was to
study the effect of B and K as foliar application at rates of 50, 75 ppm for B
while 1000 and 2000 ppm for K as silicate and K sulphate on growth and
productivity of broad bean grown sandy soil at Baloza station-North Sinai.
The obtained results indicated that the yields components of broad bean
were improved with increasing B application. The K –forms took the same
behavior of B where the K2 showed the higher effect on the yield
parameters than K1. The K silicate had the priority than sulphate. The
nutrients concentrations increased with increasing rates of K and the silicate
forms gave higher values than sulphate forms. Also N, P, K and B uptake
had the same behavior as nutrients concentrations. The most efficient
treatment was found where using the second rate of both B and K silicate
form which achieved 2.92 and 1.11 ton/ fed of shoots and seeds broad bean
plants and noticed that highest K- utilization of yields (shoot + seeds) with
K- silicate form addition.
