Abstract

Sesamum is the queen among all the oilseed crops having a wider range of adaptability to different agro-climate and is being cultivated in India due to its market value, good quality oil and nutritional content. Some important reasons for achieving low productivity of sesamum are less or no application of some fertilizer nutrients and improper selection of cultivar. Being an oilseed crop, application of primary nutrients along with sulphur can improve seed and oil yield as well as oil quality of sesamum. Sulphur plays key role in protein synthesis in oilseeds and helps in plant metabolic activity and ultimately improve yield. Along with sulphur application, selection of best suitable cultivated crop variety for a location can also enhance the productivity of sesamum. Indian farmers generally do not apply sulphur separately through a different sulphur-based fertilizer due to lack of awareness. Considering these facts, a field investigation was taken to assess the enhancement in the growth, yield, sulphur and oil content, sulphur uptake and economics of sesamum cultivars due to sulphur fertilization under this agro-climatic region. Field investigation was done during pre-kharif season of 2022 at Post Graduate Research Farm, M. S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Odisha. The present study was planned in factorial randomized block design with three different cultivars (YLM 11, Gowri and YLM 66) and four levels of sulphur (0, 20, 40 and 60 kg ha-1) replicated thrice. Sulphur was applied through bentonite sulphur fertilizer which contains 90% sulphur. As per the experimental findings, cultivation of the sesamum cultivar “Gowri” combined with sulphur application at the rate of 60 kg ha-1 was beneficial for obtaining more growth, yield, oil and sulphur content, higher sulphur uptake and economic benefit than all the other combinations of sesamum cultivar and sulphur application rate.

Conclusion

From the above findings, it can be inferred that S application along with the primary nutrients might have positive impact on the growth and yield attributes and yield vis-à-vis oil percentage of improved sesamum cultivars. Application of S at the rate of 60 kg ha-1 in combination with the cultivar, Gowri could be the best option to achieve maximum growth, yield and profit during pre-kharif season in southern Odisha region.
