Genotypic Variation for Response to Rhizobial Sp. and Piriformospora Indica for Yield and Yield Components in Mungbean [Vigna Radiata (L.) Wilczek].

Ten mungbean genotypes were evaluated to estimate the genotypic variation for seed yield components and Nitrogen and Phosphorus uptake after inoculating with three microbial treatments (Rhizobium, Piriformospora indica and their combined inoculation). Significant genotypic differences for all characters indicated presence of considerable variability. All the microbial treatments and genotype x microbial interaction differed significantly except for maturity, branches/plant and seeds/pod. The traits affected most by Rhizobium inoculation in majority of the genotypes were plant height, pods/plant and seed yield. Above 50 per cent P. indica infection in roots was observed in eight genotypes, however, its effect was observed only in a few genotypes on plant height, P content in shoot, 100-seed weight and seed yield. The effect of combined inoculation was observed on seed yield only. Effect of all the three inoculants was observed in only MH-810 and MH-721. Maximum response of Rhizobium and dual inoculation was observed in MH-421.
