Abstract
Field experiment were conducted during two consecutive years of 2011 and 2012 at Student Instructional Farm of N.D. University of Agriculture and Technology, Narendra Nagar (Kumarganj), Faizabad to study the effect of rhizobial inoculation on growth, yield, nutrient uptake and economics of summer urdbean in relation to zinc and molybdenum. Result data revealed that the seed inoculation with Rhizobium culture significantly increased growth attributes viz., plant height, number of primary and secondary branches plant-1, number and dry weight of nodules plant-1, seed and stover yield, nitrogen, zinc and molybdenum uptake, gross and monetary return and benefit : cost ratio than without inoculation. Application of 2.5 kg Zn/ha significantly increased the growth attributes, nodulation, seed and stover yield, nutrient uptake and economics of urdbean over control. Zinc uptake significantly increased up to 5.0 kg Zn ha-1. Application of molybdenum up to 1.0 kg ha-1 significantly increased growth characters, number and dry weight of root nodules, seed and stover yield, nutrient uptake, gross and net return and benefit : cost ratio
