Effect of zinc, molybdenum and Rhizobium on yield and nutrient uptake in summer urdbean (Vigna mungo L.)

A field experiment was conducted for two consecutive Zaid seasons during 2011 and 2012 at Student Instructional Farm of N.D. University of Agriculture and Technology, Narendra Nagar (Kumarganj), Faizabad to study the effect of zinc, molybdenum and Rhizobium on yield and nutrients dynamics of summer urdbean (Vigna mungo L.). Application of 5.0 kg Zn/ha, 0.5 kg Mo/ha and inoculation of seeds with Rhizobium significantly increased seed and stover yield during both the years. Besides build up of available N, Zn and Mo in soil after harvested of the crop, nitrogen uptake significantly increased following application of 5.0 kg zinc, 0.5 kg Mo/ha and Rhizobium inoculation. Zinc and molybdenum uptake were also significantly increased by the supply of 2.5 kg zinc and 0.5 kg Mo/ha.
