Zinc and manganese sulphate were applied to broad bean at Maryout and
Nobaria locations, as foliar spray in concentration 0, 1,2 and 3 gil. and as soil addition
at rates of 0, 5, 10 and 15 kg.lfed. In Maryout, growth parameters, yield and its
components and chemical composition were enhanced with foliar spray application
method than soil addition. While, method of application had no effec1 on number of
tillers/plant and net weight percentage. In Nobaria, growth and yield of broad bean
surpassed with soil addition application method than foliar spray, while method of
application had no effect on net weight ("!o) ,dry matter ("!o) and protein content of seeds.
Zinc sulphate application at 2 gil. as foliar spray or 10 kg.lfed. as soil addition
increased growth , yield and manganese content of broad bean significantly than other
zine treatments. lNhile the highest values of protein and zinc content in seeds obtained
with 3 g.1L or 15 kg/fed. Zinc sulphate application. These results obtained in Maryout and Nobaria locations. As regard manganese sulphate appUcation at 1 gil. as foliar spray or 5 kg.lfed. as soil addition increased growth, weight of 100 seed, net weight, dry matter percentage. Also, protein and zinc content in seeds increased Significantly with treatment 2g.1l or 15 kglfed. MnS04 than control treatment, but manganese sulphate application at cone. 3 g.lL or 15 kglfed. gave the highest yield of pods/plant , yieldlfed. and manganese content in seeds under Maryout conditions. In Nobaria, application of
manganese sulphate at 1 g.1l as foliar spray or 5 kglfed. as soil addition increased all
characters of broad bean under study significantly than other manganese treatments,
except manganese content in seeds surpassed with high rate of manganese application (3 g.1L or 15 kg/fed.).
