Effect of foliar application of plant growth regulators on growth and development, biochemical changes and yield of mung bean (Vigna radiata L.)

A experiment was carried out under field condition at Students Instructional Farm of Acharaya Narendra Deva University of Agriculture & Technology, Narendra Nagar, (Kumarganj), Ayodhya U.P. during kharif season 2019 based on a Randomized Blok Design with three replications, variety Narendra Mung-1 with seven treatments were taken. The foliar sprayed of GA3 75 ppm was found most effective for increasing the plant height, number of branches per plant(7.50), total dry biomass per plant (29.75 g) and chlorophyll content SPAD value (10.28), protein content in seed (24.63%), number of pod per clusters (7.39), number of pods per plant (48.92), pod length (8.92 cm), number of seeds per pod (9.21), number of seeds per plant (455.33), 100 seed weight (3.62 g), seed yield per plant (15.07g), followed by foliar sprayed of NAA 150 ppm over rest of the treatments. Generally, the use of growth regulators as foliar application increased the yield and yield components.
