Physiological Response of Homobrassinolide on Growth and Yield Component of Black Gram (Vigna Mungo L.)

Abstract

A field experiment was conducted during the kharif seasons of 2021 at farm of Botany section, College of Agriculture, Nagpur. The experiment was laid out in randomized block design and replicated thrice consisting eleven treatments i. e. Homobrassinolide (0.10 ppm, 0.20 ppm, 0.30 ppm, 0.40 ppm, 0.50 ppm, 0.60 ppm, 0.70 ppm, 0.80 ppm, 0.90 ppm and 1.00 ppm) Results revealed that foliar application of homobrassinolide sprayed at two stages i. e. 20 and 40 DAS significantly improved growth parameters like plant height, number of branches, days to 50 per cent flowering, total dry weight, leaf area and yield parameters like number of pods plant-1, test weight, seed yield ha-1 and harvest index. Treatment T11 (Homobrassinolide @ 1.00 ppm ) gave significantly higher results in all parameters under study.
