Abstract

A pot culture experiment results revealed that application of FeSo4; ZnSO4 treatments showed beneficial effects on chlorophyll content of soybean leaves, nodulation, dry weight of nodules/plant, grain and dry matter yield/plant as compared to control and treatments of CuSO4 and MnSO4 in both soybean varieties. Cholorophyll content, number of nodules/plant, fresh and dry weight of nodules/plant at 50% flowering as well as pod formation stage indicated positive correlation with seed and dry matter yield/plant. The characters showing positive association with yield/plant were also associated amongst themselves except nitrogen in nodules at pod formation stage.
