Abstract:
<p>Low nitrogen content in soil is usually overcome by chemical fertilization. After long application period, high-dose and intensive use of N fertilizers can cause ammonia volatilization and nitrates accumulation in soil. In sustainable agriculture, the use of bacterial inoculant integrated with nutrient management system has a role in soil health and productivity. Azotobacter-based biofertilizer is suggested as a chemical nitrogen fertilizer substitute or addition in crop production to improve available nutrients in the soil, provide some metabolites during plant growth, and minimize f

Abstract:
Inorganic fertilizers alone cannot sustain high levels of productivity. It may cause deterioration of soil environment leading to low productivity. An investigation was carried out to develop integrated nutrient management technology for fruit yield of bell pepper (Capsicum annuum L.). The experiment was conducted at Horticulture Research Division, Nepal Agricultural Research Council Khumaltar, Lalitpur during 2010/011. The experiment was laid out in a randomized block design with three replications and having seven treatments viz., Control (100% NPK), Azotobacter + 25% N + PK, Azotobacter + 5
