Effect of plant growth regulators on growth and yield of Zaid Mung bean (Vigna radiata L.)

Abstract

An experiment was conducted during Zaid season of 2020 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (UP) to study the “effect of plant growth regulators on growth and yield of Zaid Mung bean (Vigna radiata L.)”. The experiment was laid out in Randomized Block Design with ten treatments of plant growth regulators of Salicylic acid (100&150ppm), GA3 (50&100ppm), NAA (10&20ppm) and Chlormequat chloride (146&337ppm) foliar spray at 25 and 35 DAS and replicated thrice. Among the different treatments, treatment 4 (GA3 100ppm Foliar spray at 35 DAS) has recorded maximum plant height (47.47 cm), more number of branches per plant (4.63), more number of nodules per plant (12.85) and maximum plant dry weight (6.24 g/plant) and significantly highest number of pods per plant (33.29), number of seeds per pod (9.34), maximum seed yield (1289 kg/ha) and stover yield (2894 kg/ha) was obtained. Highest gross returns (97623 ₹/ha), net returns (64668 ₹/ha) and B:C ratio (1.96) was also noted under treatment 4 (GA3 100ppm Foliar spray at 35 DAS).
