Effect of organic amendments and micronutrients on nodulation and yield of blackgram in acid soil

Field experiment was conducted to study the effect of organic amendments such as farmyard manure, biodigested slurry, compost and press mud and micronutrients mixture containing molybdenum, cobalt, boron and iron as foliar spray and soll application on nodulation and yield of black gram under acid soil condition. The results revealed that application of press mud @ 5 Vha along with soil application of micronutrients mixture significantly increased the number and weight of nodules, biomass production, plant height and grain yield of Vamban 1 black gram.
