Effect of seed priming with plant growth regulators on growth, biochemical changes and yield of Mung bean (Vigna radiata L.)

Abstract

Seed priming is employed for better crop stand and higher yield in a range of crops. In order to evaluate the effect of seed treatments with growth regulators on the yield and yield components of mung bean (Vigna radiata L.) variety, 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 of Narendra Mung-1 with seven treatments were taken. The maximum germination percentage (90.25%) was recorded with seed priming of GA3- 100ppm over other treatments including control. Growth characters as plant height, total dry biomass, and chlorophyll content and nitrogen content in green leaves and protein content in mature seeds were found significantly superior with seed priming of GA3-100ppm followed by NAA-100ppm over control. Yield and yield contributing traits viz: number of pod clusters per plant (8.33), number of pods per plant (48.26), pod length (7.66cm), number of seeds per plant (416.66), number of seeds per pod (10.33), 100 seed weight (3.92g), seed yield per plant (14.36g), seed yield (11.66 q h-1) and harvest index (36.06%) were also found statistically superior with seed priming of GA3-100ppm followed by priming in NAA-100ppm over control.Generally, the use of growth regulators as a pre-treatment of seed increased the yield and yield components.
