Legume crops are not only used as human diet but also for edifying soil fertility through biological nitrogen fixation and Rhizobia is well known in enhancing yield of legumes. Micronutrients are imperative module of soil fertility and they manipulate crop productivity. Therefore the application of micronutrients (Zn, Fe & Mo) along with Rhizobium inoculation may improve nodulation and yield of mungbean. There are scanty reports on their combined use under arid to semiarid climate of Pakistan. A pot experiment was conducted to evaluate their effect on mungbean productivity. Treatments allocated in CRD, comprised of control, Rhizobium inoculation alone and along with two levels (2 and 4 kg per ha) of micronutrients. The performance of Rhizobium alone was superior over uninoculated control in all parameters. The results showed that increasing rate of micronutrients along with Rhizobium inoculation significantly increased mungbean productivity except molybdenum. Rhizobium inoculation along with Mo @ 2 kg per ha increased plant height, root length, 100-grain weight, nodules number per plant and nitrogen content in grains by 59, 67, 72, 162 and 8%, respectively, over uninoculated control whereas highest number of pods per plant and grain yield was obtained along with Zn @ 4 kg per ha. Number of nodules per plant was positively correlated with %N in grains and grain yield. It was concluded that micronutrients are vital for optimum activity of Rhizobium and plants inoculated with it enhanced mungbean productivity.
