A pot experiment was conducted to study the modulation effect of brassinolide under water stress and drought condition on physiology, growth and yield of green gram under normal condition till anthesis stage, the plants were sprayed with Brassinolide (0.0, 0.1, 0.5 and 1.0 ppm) concentration at 25 and 35 DAS prior to imposed stress. Water stress was found to decrease significantly in the respect of photo synthetic and transpiration rate, stomatal conductance, relative water content, chlorophyll stability index, leaf area, plant height, number of pods per plant, number of grains per pod, test weight and grain yield with a significant increase in leaf temperature and appreciable significant difference between both the varieties. The effect of Brassinolide was found to increase in the value of these parameters significantly with a decrease in leaf temperature because the effect of brassinolide was recorded to increase in the rate of transpiration at all the stages in both the cultivars of green gram up to 1.0 ppm concentration of it.
