Abstract: A field experiment was conducted in 2014-15 and 2015-16 in rabi seasons at agricultural research farm of B.H.U. to study the effect of different strain of potassium solubilising bacterias and fungi in combination with various fertility levels on the microbial status and their corresponding impact on soil health. The trial consisting of Agrobacterium, Flavobacterium, Rhizobium and fungal strain of Trichoderma and four fertility levels was laid out in a split plot design with four replication by keeping fertility levels in the main plot and strains in the subplot. Significantly higher microbial population was recorded by the use of different microbes. Different physiological growth parameters such as LAI, CGR, RGR and NAR of baby corn crop were found to be the highest with 100%NPK+ Agrobacterium sp. and it was found to be at par with 100% NP+75%K + Agrobacterium sp. found to improve the crop growth under edaphic and climatic condition.
