An experiment was conducted at Agronomy Farm, S.K.N. College of Agriculture, Jobner, during kharif season of 2017. The soil of the experimental field was loamy sand in texture. The treatments comprised of three sources (gypsum, elemental sulphur and iron pyrite) and four levels of sulphur (15, 30, 45 and 60 kg ha~(-1)) along with an absolute control (no sulphur), making 13 treatment combinations. These 13 combinations were replicated thrice in factorial randomized block design. Sesame variety RT-346was used as a test crop. The highest plant height, dry matter accumulation, number of capsules per plant, number of seeds per capsule, seed and stalk yield were achieved with gypsum application and 45 kg S ha-1, However the yield remained at par with 60kg S ha~(-1). A nonsignificant difference was recorded in harvest index on account of sources and levels of sulphur fertilization.
