Abstract:

Twenty-one genotypes of black gram were evaluated to study the impact of pre-sowing phytohormonal seed priming on root nodulation. From the present investigation, the genotype IC-261175 reported maximum root length under ascorbic acid treated seeds while the genotype IC-334268 had maximum shoot length under riboflavin treated seeds as riboflavin can lead to more vigorous seedling growth than ascorbic acid. Genotype IC-426495 reported the highest number of nodules per plant and the number of active nodules under ascorbic acid treated seeds. At both the genotypic and phenotypic levels, correlation coefficient analysis showed that seed yield per plant showed a substantial and positive link with number of major branches, number of pods per plant, pod length, seed index, and harvest index. The present study thus concludes that seed priming in Vigna mungo with ascorbic acid, riboflavin is capable of augmenting plant growth, nodulation and also ameliorates soil fertility as the active nodulation induced by seed priming aids in the conversion of atmospheric nitrogen into nitrogen compounds taken up by plants by the left behind nitrogenous compounds reclaim the soil fertility.
