EFFECT OF DIFFERENT MICROBIAL INOCULANTS ON YIELD, MICROBIAL POPULATION AND CHEMICAL PROPERTIES IN SOIL OF GROUNDNUT GROWN ON VERTISOL
Journal Title: International Journal of Microbiology Research - Year 2017, Vol 9, Issue 1
Abstract
The experiment was conducted on zinc deficient soil on farmer’s field Parbhani, Maharashtra during summer season of 2014 to assess the ability of different microbial inoculants in improving the yield, microbial and chemical properties of soil by taking groundnut as a test crop. Bioinoculants used such as Burkholderia cepacia, Burkholderia cenocepacia, Pseudomonas fluorescens, Pseudomonas striata, Trichoderma viride, Trichoderma harzianum and Bacillus megaterium. Tenth day after sowing 24 hrs old fresh culture of microbial isolates was inoculated at the rate 10 ml per plot. The results indicated that highest values of actinomycetes and bacterial population were noted in treatment RDF +Rhizobium and Bacillus megaterium whereas, fungal population was highest in the RDF+ Rhizobium+ Trichoderma sp. treated soil. Among the chemical properties of soil such as pH, EC and CaCO3 after harvest of groundnut showed non-significant results. However, soil organic carbon was also influenced significantly with the seed inoculation of Rhizobium and Pseudomonas striata along with RDF as compared to controls.
