Effect of PGRs on Biochemical Parameters and Yield Attributes of Black gram(Vigna mungoL.)

Abstract

An investigation was conducted to find out the effect of GA3 and salicylic acid on biochemical parameters and yield attributes of black gram (Vigna mungo L.) cv. Narendra Urd-1. The crop was grown under field condition, and GA3 concentrations 50, 100 and 150 ppm and salicylic acid concentrations 100, 125 and 150 ppm were applied as a foliar spray at different growth stages. That resulted in the foliar spray of SA 150 ppm at 25, 40 and 55 DAS, and was found most effective to increase the biochemical parameters, namely, total chlorophyll content, nitrate reductase activity, nitrogen content in leaf, protein content in seed and yield attributes viz. number of pod per cluster, number of pod cluster per plant, pod length, number of seeds per pod, number of seeds per plant, seed yield per plant and seed yield quintal per hectare.
