Abstract:
A field experiment was carried out at CCS Haryana Agricultural University, Hisar (Haryana) during kharif 2020 to study the effect of inorganic fertilizer, organic manure and biofertilizer for yield maximization of mungbean [Vigna radiata (L.) Wilczek] and their residual effect on succeeding mustard crop. The experiment was conducted with three sources of nutrients having eighteen combination viz., three fertilizers doses i.e 75%, 100% and 125% of recommended dose of fertilizers (RDF) with two FYM levels (no fym and 5 ton/ha. fym) and three biofertilizers i.e. Rhizobium, LNm 16 and Rhizobium + LNm 16 in Factorial Randomized Block Design replicated thrice. It was found that in 100% RDF recorded significantly higher seed yield (737.39 kg/ha), 1000 seed weight (38.92) and pods per plant (25.75) of mungbean over 75% RDF (583.11 kg/ha, 37.72 and 23.37), respectively. Seed yield in 100% RDF was higher to the tune of 26.46 percent over 75% RDF. The application of 5 ton/ha FYM recorded significantly higher seed yield (713.48 kg/ha), pods per plant (25.19) and branches per plant (3.26) over control. Seed inoculation with Rhizobium + PSB strain LNm 16 recorded maximum and significantly higher seed yield (706.45 kg/ha), branches per plant (3.2) and pods per plant (25.08) over seed inoculation with PSB strain LNm 16. Residual effect of different fertilizers level on mustard crop yield was non significant whereas seed yield of mustard crop was significantly effected by residual effect of FYM application and it was highest (3540) at 5 ton/ha FYM over control.
