Effect of Sulphur and Molybdenum Application on Yield and Protein and S-Amino Acid Contents of Green Gram (Phaseolus aureus)

Results of a field experiment conducted to study the effect of application of sulphur as K₂SO₄ and molybdenum as Na₂MoO₄ to a Vertisol of Vidarbha, showed that the application of sulphur @ 30 kg/ha significantly increased the protein content of green gram (Phaseolus aureus) grains. Cystine and methionine contents of the grains also tended to increase with S application, while molybdenum had little effect on protein, cystine and methionine contents. The grain yield remained unaffected by the application of either S or Mo.
