Effect of Rhizobium Inoculation with Zinc and Boron Fertilizers on Growth and Yield of Mungbean (Vigna radiata L.)

Mungbean is considered as an extremely nutritious crop possessing a high level of micronutrients. The field experiment was conducted to evaluate the response of growth and yield of Mungbean to zinc, boron and rhizobium inoculation. The experiment was laid out in split-plot design with tree replications during kharif season of 2021 and 2022 at Instructional farm, Kamla Nehru Institute of Physical and Social Sciences Sultanpur, U.P. India. Four levels of zinc (0, 2.5, 5.0 and 7.5 Kg Zn ha-1), three levels of boron (0, 0.5 and 1.0 Kg B ha-1) and two levels of rhizobium i.e. Uninoculated (Control) and inoculated were used in this study. Zinc levels were allocated to the main plots, boron levels in the sub-plot, while Rhizobium inoculation in the sub-sub plot. The results revealed that plant height, number of branches per plant, dry weight, number of nodules and seed and stover yield were higher in mungbean inoculated with Rhizobium inoculation with application of zinc 7.5 kg ha-1 and Application of boron 1.0 kg ha-1. The findings of the current study would improve the growth and yield of mungbean.
