ABSTRACT

Sulphur fertilization assumes substantial influence in improving the yield and quality of oilseed crops. The relationship between sunflower seed yield and sulphur dose applied was determined using quadratic model and the economically optimum sulphur dose was calculated via marginal analysis for yield maximization and profit over fertilizer cost. Economically optimum dose of sulphur for sunflower was found to be 32.99 and 38.95 kg/ha under semi-arid irrigated conditions during 2008 and 2009, 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 2.8 to 4.0 kg/ha.
