The relationship between sesame seed yield and sulfur dose applied was determined quadratic model and the economically optimum sulfur dose was calculated via marginal analysis for yield maximization and profit over fertilizer cost. To determine optimum sulfur dose in sesame production under middle Gujarat conditions, data obtained by field experiments carried out in 2012 and 2013. Economically optimum dose of sulfur for sesame was found to be 21.61 and 19.65 kg ha−1 under middle Gujarat conditions during 2012 and 2013, respectively. Over-fertilized condition of S for maximum output did not bring out any significant advantage viewing almost identical seed yield both at physical and economic optimum of S indicating a saving of S from 1.4 to 1.7 kg ha−1.
