Effect of zinc and sulphur on protein and oil content of soybean

Results of field experiment conducted duririg kharif 1997 to study the effect of application of zinc as zinc oxide and sulphur as gypsum on soybean (PKV-1) showed that the application of zinc and sulphur with increasing levels, significantly increased the protein and oil content of soybean grain over control. Highest protein (37.25%) and oil (20.42%) content was observed due to application of 3 kg Zn ha⁻¹, while 40 kg S ha⁻¹ gave the highest protein (37.25%) and oil (21.29%) content of soybean grain.
