Abstract:
Green gram (Vigna radiata L.) commonly known as mungbean, is one of the most important pulse crop which has high nutritive value, ability of biological nitrogen (N₂) fixation and ability of addition of organic carbon to soil. The basic concept behind the appropriate nutrient management from different sources is to maintain the balance between need and supply of nutrients while reducing the adverse impact of imbalanced fertilization simultaneously. Considering these facts the field experiment was carried out to boost the production of mungbean. The experiment was conducted, during Kharif season of 2019 at N. E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar. The experiment comprised of 18 treatment combinations with three inorganic levels viz., 75% (15:30:15), 100% (20:40:20) and 125% (25:50:25) of N: P₂O5: K₂O, and two farm yard manure levels (control and application of FYM @ 5 t/ha) and three biofertilizers treatments (Rhizobium, LNM-16 and Rhizobium + LNM-16) was laid out in factorial randomized block design with three replications. In present investigation the inorganic fertilizer level of RDF 125% is found better in terms of plant height, yield attributes and yields of mungbean followed by RDF 100% and RDF 75%. The application of 5t/ha FYM is found superior over control in terms of plant height, dry matter accumulation, growth rates, yield attributes and yields. The combine inoculation of Rhizobium culture (Rhizobium + LNM-16) is found comparatively better from solo application of Rhizobium and LNM-16.
