Effect of Plant Growth Regulator and Crop Geometry on Growth and Yield of Green Gram (Vigna radiata L.)

A field trial was conducted during the Zaid season of 2023 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) on the Green Gram (Vigna radiata L.). The experiment was executed in a Randomized Block Design with ten treatments and replicated three times. Application of brassinolide 0.25% and plant density 35 cm x 10 cm (T2) recorded highest plant height (78.70 cm), dry weight (33.25 g/plant), number of nodules/plant (28.93), number of pods/plant (42.00), number of seeds/pod (14.00), test weight (31.89 g), seed yield (1273.70 kg/ha), stover yield (3401.50 kg/ha) and harvest index (27.24 %). however, maximum crop growth rate (8.87 g/m2/day) was recorded in GA3 0.50% + 25 cm x 15 cm (T7). Maximum gross returns (INR 89,159.00/ha), net returns (INR 56,539.00/ha), and B:C ratio (1.73) were also obtained highest in the same treatment (T2) in Green Gram crop. Therefore, application of brassinolides 0.25% and plant spacing 35 cm x 10 cm (T2) result in significant improvement in the crop production and also proven economically viable in green gram.
