An experiment was carried out at the Instructional farm, College of Agriculture, Bikaner during Kharif 2017-18 on loamy sand soil. The experiment comprising of four sources (Gypsum, ES, SSP + Gypsum and SSP+ES) and four levels of sulphur (30, 45, 60 and 75 kg ha-1) along with an absolute control (no sulphur) making 17 treatment combinations. These 17 combinations were replicated three times in factorial randomized block design. Results showed that application of sulphur through SSP + gypsum, significantly increased the dry matter accumulation at 30, 60 DAS and at harvest. These sources @ 60 kg S ha-1 except plant stand at 30 DAS and at harvest. gave significantly higher dry matter accumulation at 30, 60 DAS and at harvest, plant height at harvest over control and which was statistically at par with 75 kg S ha-1. Application of sulphur up to 60 kg S ha-1 increased the biological yield of sesame significantly over preceding levels. The increase in biomass with this level was 12.51 and 7.88 percent over 30 and 45 kg S ha-1, respectively. Maximum biological yield was recorded in 75 kg S ha-1 treatment which was statistically at par with 60 kg S ha-1. Application of sulphur through SSP + gypsum produced significantly higher biological yield (3647.7 kg ha-1) which was 8.48, 7.66 and 6.60 percent higher over ES, ES+SSP and gypsum, respectively. Application of SSP + gypsum significantly increased the plant height and dry matter accumulation and crop productivity over ES+SSP, gypsum and ES. Among the sources and levels of sulphur application, SSP + gypsum recorded higher total biomass up to 75 kg S ha-1.
