Abstract: The experiment was conducted in Randomized Complete Block Design with three replications during 2016-17 & 2017-18 to assess the performance of growth regulators, micronutrients and chemicals on yield and yield traits of acid lime. The experiment was conducted on the Experimental area, College of Agriculture, Gwalior (M.P.). The role of growth regulators, micronutrients and chemicals is very crucial in growth and quality improvement of fruit crops. Study was undertaken to investigate the different combinations of plant growth regulators (GA₃ and NAA), micronutrients (FeSO₄ and Boron) and chemicals (KNO₃ and Salicylic acid). Treatment GA₃ 100 ppm + KNO₃ 2% + Salicylic acid 200 ppm + FeSo₄ 1% + Boron 1% (T₁₁) shows significant variance regarding fruit length (4.64 cm), fruit diameter (4.59 cm), average fruit volume at harvest (41.8 cc), number of fruits perplant (974.2) and average yield per tree (38.3 kg). Treatment (T₁₁) observed maximum net income (Rs. 79,852.5) with highest cost benefit ratio (1:1.71).
