Effect of Rhizobium inoculation and nitrogen fertilizer on yield and yield components of mungbean

Mungbean (Vigna radiata L.) is capable of fixing atmospheric nitrogen through Rhizobium species living in its root nodules. To evaluate the effect of inoculations and nitrogen levels on performance of mungbean, a pot experiment was conducted during spring 2004. Mungbean variety NM-98 was sown at 20 kg ha-1 in pots. Seed and soil inoculation, and nitrogen levels at 15, 30 and 45 kg ha-1 were applied. Data on recorded on number of pods per plant, number of seeds per plant, 100-seed weight and seed yield were recorded. Yield and yield components of mungbean crop were significantly affected by both inoculation and fertilizer application. Seed inoculation was more affective and gave better results than soil inoculation.
