Root Parameters of Blackgram (Vigna Mungo L.) Improved by Seed Pelleting With Nutrients and Foliar Spray of Nutrients and Plant Growth Regulator

Abstract

In the study, a treatment combination of DAP 40 g kg 1 seed, DAP 40 g + KCl 10 g kg -1 seed, DAP 40 g + KCl 10 g + Gypsum 20 g kg -1 seed and control in main plot and foliar spray treatments i.e., DAP 2%, DAP 2% + KCl 1%, DAP 2% + NAA 40 ppm, DAP 2% + KCl 1% + NAA 40 ppm at two(30 & 45 DAS) and three (30,45 & 60 DAS) times totally eight treatment in sub plot were evaluated and found that a treatment combination of DAP 40 g + KCl 10 g + Gypsum 20 g kg -1 seed and DAP 2 % + KCl 1 % + NAA (40 ppm) at 30, 45 & 60 DAS registered higher root length, root nodule and nodule weight in blackgram crop in both the seasons.
