Influence of fertility and sulphur management on growth parameters, yield attributes and production potential of Sesame (Sesamum indicum L.)

Abstract

A field experiment was conducted during kharif 2024 at the Agricultural Research Farm, School of Agriculture, Suresh Gyan Vihar University, Jaipur, to study the “Influence of Fertility and Sulphur Management on growth parameters, yield attributes and production potential of Sesame (Sesamum indicum L.)”. The experiment was laid out in a factorial randomized block design with 16 treatment combinations, comprising four fertility levels (control, 50%, 75% and 100% RDF) and four sulphur levels (0, 20, 40 and 60 kg ha-1), replicated three times. The results indicated that the conjunctive application of 100% RDF and 40 kg S ha-1 significantly improved growth parameters viz., plant height, dry matter accumulation, branches plant-1 and chlorophyll content, while yield attributing traits also responded positively, with the highest capsules plant-1, seeds capsule-1 and test weight. This treatment produced the maximum seed yield, stalk yield and biological yield in the test variety RT-351, representing a yield advantage of over 30% compared to control. The findings highlight the significance of balanced NPK fertilization in conjunction with sulphur for enhancing growth, yield attributes and productivity of sesame under semi-arid eastern platue zone of Rajasthan.
