Abstract

Two field trials were conducted on Sandy loam and calcareous
soils at Agric. Res. Stations of Ismailia and Nubaria, during the
growing season 2003/2004 to study the effect of spraying NPK with or
without micronutrients on the growth, yield, yield components and seed
protein percentage of faba bean crop.
Generally, foliar spray with P and/or K with or without
micronutrients, increased dry matter production, nutrients uptake, seed
yield and seed protein percentage. However, the maximum figures were
obtained when the mixture of 2% N as urea + 2% P as superphosphate
+ 1 % K as potassium sulphate + chelate of Fe, Mn, and Zn was used,
two times (after 50 and 70 days from sowing). Results, also showed
that the response of faba bean, in general, varied according to the
location, soil fertility, kind and rate of the added fertilizers.
