The present study was conducted at Horticultural Research and Training Station and Krishi Vigyan Kendra (HRTS & KVK), Kandaghat, Solan, Himachal Pradesh, India. This study was done to evaluate the change in microbial and enzyme activity of rhizospheric soil by application of biofertilizers, organic and chemical fertilizers during the year 2017-18. The results showed that maximum azotobater, PSB and actinomycetes population was found significantly higher with 80% RDF (25% CN + 75% Urea) + 20% N (VC) + (Azotobacter + PSB @ 25g/tree) during both the years of study. However, minimum was found in 100% RDF (100% N through CN). Soil enzyme activities were also found significantly higher with biofertilizes in combination with organic and chemical fertilizers. Soil enzyme activities (Urease, dehydroginase and alkaline phosphotase) were observed maximum when chemical fertilizers are applied in combination with vermicompost and biofertilizers as compared to control (chemical fertilizers without vermicompost and biofertilizers). It can be concluded that application of chemical fertilizers along with organic and biofertilizers can enhance the biological properties soil.
