Effect of sulphur and gibberellic acid on growth and yield of sesame

Abstract

A field experiment was conducted during zaid season of 2024-25 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences to determine “Effect of Sulphur and Gibberellic acid on growth and yield of Sesame”. The treatments consisted of three levels of Sulphur (30, 40 and 50 kg/ha) and three levels of Gibberellic acid (100, 150, 200 ppm) along with recommended doses of fertilizer and a control (50-40-30 kg N-P-K/ha). The experiment was laid out in a Randomized Block Design with 10 treatments and replicated thrice. The results revealed that the significantly higher plant height (112.79 cm), higher plant dry weight (12.79 g) were recorded in treatment 6 (Sulphur 40 kg/ha + GA3 200 200 ppm) and maximum number of capsules/plant (38.60), maximum number of seeds/capsule (68.53), were recorded in treatment 5 (Sulphur 40 kg/ha + GA3 (150 ppm).
