A field experiment was conducted during the Zaid season of 2020 at the experimental field of the Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Technology and Sciences, Prayagraj, 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 1. Gibberellic acid (50mg/l, 100mg/l) 2. Indole Acetic acid (50mg/l, 100mg/l) and two bio-fertilizers 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 till 4. Report of the study indicates 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 highest Leaf area (36.2cm2), Plant Dry weight (13.40g) at 60 DAS and Crop Growth Rate

Plant growth hormones, Bio-fertilizers, Gibberellic acid (GA3), Indole acetic Acid (IAA), Azospirillum, Azotobacter.

Among all treatments, T5 (GA3 at 100 mg/l + Azotobacter) was found to be the best by obtaining highest growth and also the better B: C ratio. Thus, Treatment T5 is more productive, when compared to other treatments and control.
