Randomized field experiments were conducted to study the interactive effect of sulphur (S) and nitrogen (N) on seed, oil and protein yield of two cultivars of groundnut Arachis hypogea: cv Amber (V1) : cv Kaushal, (V2) . Two dosage levels of sulphur (0~;and~;20kg~;ha-1 ) and two dosage levels of N (23.5~;and~;43.5kg~;ha-1 ) in various combinations were tested as micronutrient treatments, T1,~;T2,~;and~;T3 . Results indicated significant enhancement of the yield components namely seed and oil yield as well as seed protein. Maximum response was observed with treatment T3 (having 20kg S and 43.5kg N ha-1) . Increase in seed and oil yields of 90% and 103% in V1 , and 79 and 90% in V2 , respectively were recorded as compared to the control treatment T1 (having 0kg S and 23.5kg N ha-1 ). Effect of S and N interaction was observed on protein, N and S content in seeds. The results obtained by these experiments clearly suggest that judicious balanced application of N and S could improve the yield.
