Abstract:
A field experiment was carried out during the two consecutive Zaid and Kharif season in year of 2020-2021 and 2021-2022 at the research farm of Tirhut College of Agriculture, Dholi, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar to study "yield maximization through agronomic management in Mungbean (Vigna radiate L.) under a rice-based cropping system’’. In seed inoculation with LSMR 1 (Stenotrophomonas maltophilia) + RB 3 (Microbial consortia), significantly higher N, P, K uptake of Mungbean and rice were recorded, but in the case of weed management, two-hand weeding at 20 and 40 DAS are observed significantly higher N, P, K uptake of Mungbean and rice as well as Propaquizafop 2.50% + imazethapyr 3.75% ME @ 125g/ha at 15-20 DAS was found at par response with two-hand weeding at 20 and 40 DAS. However, foliar nutrition of 2% 19:19:19 NPK (Flower initiation + Pod initiation) is shown to be significantly higher nitrogen uptake then the other rest of the treatments for Mungbean and rice, but in case weed maximum N, P, K uptake was found in seed inoculation (Rhizobium + PSB (Local) and lowest N, P, K uptake was recorded in LSMR 1 (Stenotrophomonas maltophilia) + RB 3 (Microbial consortia). Under weed management in weed check similarly in foliar nutrition in water spray (Flower initiation + Pod initiation) maximum N, P, K uptake was recorded in weed than the rest of treatments in both year (2020-2021) and pooled data respectively.
