EFFECT OF ZINC SOLUBILIZING MICROORGANISMS IN ENHANCING ENZYME ACTIVITY AND NUTRIENT AVAILABILITY IN GROUNDNUT GROWN ON VERTISOL
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 49
Abstract
The experiment was conducted on zinc deficient soil at farmer’s field in Kehal village, Taluka Jintoor, Dist. Parbhani, Maharashtra during summer season of 2014 to assess the ability of zinc solubilizing microorganisms to enhance the zinc availability and enzyme activity in soil. 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. Activity of alkaline phosphatase and acid phosphatase was noted significantly highest in treatment RDF + Rhizobium + Bacillus megaterium and respectively. However, dehydrogense activity and nutrient availability was found significantly highest in treatment whereas, significantly highest periodical Zn content in soil was found with Pseudomonas striata followed by Pseudomonas fluorescens and Trichoderma viride, respectively.
