Effect of growth regulators, micronutrients and chemicals on reproductive and quality of acid lime cv- Vikram in Ambebahar under High density planting system (Citrus aurantifolia Swingle)

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 reproductive and quality 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 days to flower budinitiation (38.5 days), days to 50% flowering (49.0 days), days to fruit setting (72.0 days), fruit setting percentage (87.1 %), fruit retention percentage (84.5 %) and fruit drop percentage (15.5 %), total soluble solid (8.93 0Brix), total acid (6.62 %) and ascorbic acid (29.9 mg).
