Abstract
Field experiments on mung beans (Vigna Radiata L.) Wilczek were conducted using lignitic derived humic acids. The study includes soaking of seeds with 0.005% aqueous humate and followed by spray of humate solution with variable concentrations (0.001 — 0.0075 g/l/m2). Effect of supplementation with Sarsabz (a micronutrient formulation) was also studied. Significant effects were observed on plant height, root weight, No. of pods, pod length, pod grain weight, dry weight of plant, waste material, seed protein value and yield of grain. The experimental results showed that humic acids greatly enhance the yield of mung beans, at concentration 0.05%, which is almost doubled as compared to controls.
