Main plot consisting of two sources (sulphur bentonite and gypsum) and sub-plot consisting of 4 levels (10, 15, 20 and 25 kg ha-1). The results indicated that, application of sulphur at 25 kg ha-1 to the sesame crop from both the sources (sulphur bentonite and gypsum) increased the seed yield significantly. Application of sulphur at 25 kg ha-1 resulted in significantly higher plant hieght at harvest (133.20 cm), number of branches per plant (3.90), dry matter accumulation (10.90 g ) ,number of capsules per plant (65.60), and seed weight per plant (6.00 g), seed yield (899 kg ha-1), over other levels of sulphur (10, 15, and 20 kg ha-1). Application of sulphur at 25 kg ha-1 to the sesame improved the quality parameters like oil content (48%), oil yield (435 kg ha-1), and seed protein (18%) as compared to control. Among the levels of sulphur applied, significantly higher net returns (Rs. 41,002.00 ha-1) and benefit cost ratio (3.0) was recorded with application of sulphur at 25 kg ha-1 irrespective of sulphur sources as compared to control (Rs. 14,497 ha-1) and (2.0) respectively. Both the sources of sulphur i.e. sulphur bentonite and gypsum were on par with respect to seed and oil yield and also increased the net returns and benefit cost ratio. Significantly higher growth, quality and yield parameters are obtained in the treatment received sulphur at 25 kg ha-1 with gypsum source.EnglishThesis
