Studies were carried out to evaluate the response of cotton to Multinutrient Supersulphate-SG100 as a sulphur fertilizer under field conditions. The treatments consisted of 0, 125, 250, 375 and 500 kg Multinutrient Supersalphate- SG100 per hectare. Cotton cultivar CIM446 was planted in the last week of May in a randomized complete block design and had four replications. All experimental units also received 50 kg P2O5 ha-1 at planting and 150 kg N ha-1 in three split doses i.e. planting, flowering and peak flowering stages. The crop vas kept free of pests with scheduled sprays and standard crop husbandry practices of the area were followed during the season. Experimental results showed significant increase in seed cotton yield due to application of multinutrient supersulphate. The addition of 125 kg supersulphate per hectare seemed sufficient to overcome sulphur deficiency in silt loam soils for optimum cotton production. The petiole sulphate-sulphur concentration increased with increasing doses of supersulphate fertilizer. These responses were obtained in soils having sulphate-sulphur (SO4-S) availability of 8-10 mg kg-1 of soil.
