Abstract
The goal of the current study was to evaluate the impact of pre sowing phytohormonal seed priming on growth, yield, nodulation, heritability, genetic variability, genetic advance, genetic diversity analysis for Greengram (Vigna radiata L.) genotypes for 16 quantitative characters during Kharif 2023 in the field experiment centre, Department of Genetics and Plant Breeding, Naini Agriculture Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Uttar Pradesh. To perform the study, 16 quantitative traits of 20 greengram genotypes were measured using randomized block design replicated thrice. Due to the efforts of promoting sustainable farming systems, new approaches to increasing crop yields without compromising the productivity of the land have been achieved. In order to recover soil fertility by encouraging active nodulation, this study investigates a sustainable method for improving mungbean production and growth. The best approach, therefore, is to apply organic amendments that promote promotion of soil microbial activity together with bio-inoculants whereby specific rhizobial strains that have exhibited be hallmark efficiency in nitrogen fixation will have to be adopted. The technology is aimed at increasing the efficiency of the interaction between mungbean roots and rhizobial bacteria through the optimization of the inoculation process and changes in the management practices of the root environment. This study assesses how this approach affects mungbean growth metrics, yield, and markers of soil fertility, like microbial diversity and nitrogen content. The aim of the study is to show a strong correlation between improved soil nutrient levels and microbial health and increased plant growth and output. The phytohormones are effective in decreasing the chemical nitrogen requirement and are useful for environment friendly farming. Out of tested 20 genotypes MGG – 347, TM 2000 – 2, PANTM - 4, PAU – 911 and DGGS - 4 have exhibited high seed yield per plant due to enhanced nodulation. Phytohormonal approach enhances better plant health and creates a healthier state of the soil in the long run. This acts as a positive strategy regarding soil reconditioning as well as a general improvement of the palette of the existing bio landscape regarding the prospect of expanding mungbean cultivation in a manner that is enduring.
