Maximizing Nutrient Efficiency and Profitability: Integrating NADEP Compost and Phosphorous Solubilizing Bacteria in Black Gram (Vigna mungo. L) Cultivation

Chemical fertilizers primarily focus on providing a few essential nutrients such as nitrogen, phosphorus, and potassium (NPK), neglecting other micronutrients required for healthy plant growth. This imbalance can lead to nutrient deficiencies in plants subsequently the food produced. Contributing better security improved nutrition growing population, these organic manures biofertilizers provide plants, improving their content overall nutritional quality, which are highly valuable addressing needs of population. Contrarily, imbalanced decreases productivity deteriorates soil fertility, inturn increases cost cultivation. problem be only solved by quantifying biofertilizer integration with nutrients. With this mind, an experiment was conducted 2021 at crop research center ITM University's School Agriculture Gwalior, Madhya Pradesh. Using randomized block design three replications different bio-fertilizers. There ten distinct treatments (from T1 T10). Different types had substantial impact intake. The highest uptake (N, P, K, Zn) achieved when NADEP-2 t/ha + PSB-2.5 lit/ha (T7) applied manner comparable absolute control, that is, without treatment biofertilizer. Furthermore, economics treatment, maximum gross returns (Rs 1,48,995 ha-1), net 1,11,335 ha-1) B:C ratio (2.95) recorded under T7 Urd bean.
