A study was done to see how different ways of adding nutrients affect the growth of black gram plants. By using a mix of chemical fertilizers, vermicompost, and biofertilizers, the plants grew the best. The plants had the highest seed, straw, and biological yields when given a mix of 40 kg P2O5, 2.5 t vermicompost, Rhizobium, and PSB. They also absorbed the most nitrogen, phosphorus, and potassium with this mix.
