Influence of Sources of Sulphur and Zinc on Growth and Yield of Sesame (Sesamum indicum L.)

A field experiment was carried out during kharif 2022 at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Prayagraj, (UP). The soil had a sandy loam texture, with a pH of 7.5, organic carbon (0.625%) and EC (0.564 m.m cm-1), Nitrogen (278.48 kg ha-1), Phosphorus (38.2 kg ha-1) and Potassium (240.7 kg ha-1). The experiment was laid out in Randomized Block Design with nine treatments and control which are replicated thrice based on one year of experimentation. The treatments consisted of 3 levels of source of sulphur (Gypsum 300 kg/ha-1, Single super phosphate 20 kg/ha-1, Elementary Sulphur 40 kg/ha-1) and zinc (5, 10, 15 kg/ha-1) as a Basal application and a control. The application of Gypsum 300 kg/ha-1 + Zinc 15 kg/ha-1 recorded significantly higher Plant height (110.73 cm), Plant dry weight (15.71 g/plant), number of Capsules/plant (51.40), Seeds/capsules (55.47), Test weight (2.70 g), Seed yield (1.07 t/ha) were recorded with the treatment of Gypsum 300 kg/ha + Zinc 15 kg/ha.
