Summary:In the present study, the effort has been taken to analyze the effects caused by agrochemicals.The best alternative to agrochemicals is biofertilizers. It is necessary to understand thebeneficial role played by biofertilizer in crop production and regaining the soil fertility. Thus, thepresent study compares the effect of agrochemicals [fertilizers (urea), fungicide (carbendazim)and insecticide (endosulfan)] and biofertilizers (Azotobacter sp.) on maize under nursery trialswere carried out in Complete Randomized Block Design (CRBD) by altering the presentrecommendation. The effect of above-mentioned treatments was studied based on the maizegrowth, phytochemical concentrations, soil fertility level and microbial population. Thetreatment with Azotobacter sp. and actual recommended dose of urea were performing wellwhen compared to other agrochemical treatments. The higher the concentration ofagrochemical application, lower is the plant growth. It is incurred from the study that generallythe usage of agrochemicals was seriously disturbing plant biotic characters and soil ecology.
