Effect of Potassium and Sulphur on economics and optimum does of Sesame (Sesamum indicum L.)

A field experiment was conducted at Agronomy farm, S.K.N. college of Agriculture, Jobner (Rajasthan) during kharif 2014 on loamy sand soil. The experiment consisted 16 treatment combinations of four levels each of potassium (0, 25, 50 and 75 kg ha-1) and sulphur (0, 20, 40 and 60 kg ha-1).The results showed that according to economic and marginal analysis, progressive increase in level of potassium upto 50 kg K2O ha-1 and sulphur 40 kg S ha-1 seemed highly practical due to higher net returns, benefit-cost ratio (BCR) and optimum dose of potassium and sulphur for sesame crop were computed as 63.94 kg K2O ha-1 and 53.93 kg S ha-1, respectively
