Abstract:
A field experiment was conducted during Zaid season of 2020 at experimental field of the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj, and Uttar Pradesh, India to determine the “Effect of Plant growth hormones and Bio-fertilizers on Growth and yield of Sesame (Sesamum indicum L.)”. The experiment consisted of 2 levels of two plant growth hormones viz. Gibberellic acid (50 mg/l, 100 mg/l) Indole Acetic acid (50 mg/l, 100 mg/l) and two bio-fertilizers viz. Azospiriluum and Azotobacter at 20g/kg seed. The experiment was carried out through a statistical design of Randomized Block Design (RBD) with three replications. Variety used was Gujarat til 4. Report of study indicate that, among different levels of plant growth hormones and bio-fertilizers the application of 100 mg/l of GA₃ to the Azotobacter treated plots produced significantly higher leaf area (43.4cm²), dry weight/plant (18.9g), number of capsules per plant (39.30), number of seeds per capsule (40.00), test weight (2.95), seed yield (895 kg/ha) and Harvest index (36.94). However, the application of GA₃ at 100 mg/l and Azotobacter was found to be effective in producing maximum percentage of oil content (48.28%).
