Comparative Analysis on Infuence of Cowdung and Neem Leaf Compost Amendment in Soil on Rhizospheric Microorganisms of Tomato Plant

Abstract

Two organic fertilizers were prepared by composting cowdung and neem leaves for four months and after composting the compost were added to soil in the ratio 1:3. Then tomato seeds were germinated and rhizospheric soil samples were collected and analysed for microbial count after 15, 30, 45, 60, 75 and 90 days of plant growth. The results showed that the compost NL and CD both have significant positive influence on rhizospheric bacteria and fungi. However the effect of NL compost was more on bacterial count and CD compost on fungal count. The compost amendment effect was more promising on rhizospheric microbiome at early stages ,i.e. at 15 and 30 days of plant growth.
