Effect of micronutrients on nodulation and yield of black gram in acid soil conditions

摘要

Field experiment was conducted to study the effect of micronutrients application (molybdenum, boron, cobalt and iron) on nodulation and yield of black gram under acid soil condition. The results revealed that application of all the four micronutrients in combination of Mo - 50 ppm; B - 0.2 percent; Co - 50 ppm and Fe - 0.2 percent recorded the maximum nodules/plant, nodule weight/plant, plant height, biomass production and grain yield of Vamban 1 black gram.
