Abstract

The research work was carried out during Kharif 2019 in the Experimental field, Department of Soil Science, JNKVV, Jabalpur (M.P.) under RBD with 3 replications having 16 treatments comprising different combinations as consortia of Rhizobium sp., PSB (Bacillus sp.), actinomycetes (Streptomyces sp.), Rhodopseudomonas sp., Lactobacillus sp., Saccharomyces sp. and Aspergillus sp. In addition, these, two types of control plots were maintained as fertilized uninoculated control (FUI) and unfertilized uninoculated control (UFUI), and the available nutrient contents (N, P & K) and populations of the microbial species were estimated at harvest. The outcome of the study revealed that Consortia of microbial inoculants T14 increased the highest content of available nutrients (N, P and K) by 50.28, 57.60 & 34.48%, respectively (FUI: 194, 14.10 & 242 kg ha-1), and the population of microbial species viz., Rhizobium, Bacillus, Streptomyces, Rhodopseudomonas, Lactobacillus, Saccharomyces and Aspergil

Conclusion

The result of the investigation showed that the application of consortium T14 (consortia of Rhizo + PSB + Strepto + Rhodo + Lacto + Saccharo + Aspergil) as seed inoculation performed the best consortium for enhancing seed and stover yield of soybean. Similarly, for soil parameters, the same treatment combination performed significantly better towards soil available nutrient contents of N, P and K and rhizospheric microbial populations (Rhizobium, Bacillus, Streptomyces, Rhodopseudomonas, Lactobacillus, Saccharomyces and Aspergillus) at post-harvest. In every case, the treatment combinations of T13, T11 and T12 exhibited as the next ensuing performance group. This was attributed due to the different chemical and biochemical secretions by the microbial consortia which leads to vigorous plant growth and systemic resistance (ASR and ISR), enhancement of the protein and RNA synthesis for better production of soybean.
