Enumeration of Different Nutrient Management Practices in the Yield of Black Gram (Vigna mungo L.)

A field experiment was conducted at Nalanda College of Agriculture, Trichy, during (June - August, 2025) to study different nutrient management practices on black gram. The treatments comprised Control (T₁), 100 % Recommended Dosage of Fertiliser (T₂), 100% Farm Yard Manure at 5 t ha^-1 (T₃), 100% Vermicompost at 3 t ha^-1 (T₄), 50% Recommended Dosage of Fertiliser + 50% Vermicompost (T₅), 50% Recommended Dosage of Fertiliser + 50% Farm Yard Manure (T₆) and 50% Recommended Dosage of Fertiliser + 25% Farm Yard Manure + 25% Vermicompost (T₇). The experiment was laid out in a randomised block design with three replications. Farmyard manure, Vermicompost, and Recommended Dose of fertiliser were basally used in the treatments. The result revealed that among the different treatments imposed, application of 50% Recommended Dosage of Fertiliser + 25% Farm Yard Manure + 25% Vermicompost recorded the highest growth attributes like plant height (29.85 cm), leaf area index (4.41), dry matter production (2129.93 kg ha^-1), number of branches plant^-1 (7.06), number of leaves plant^-1 (36.06) and yield attributes like number of pods plant^-1 (27.96) pod length (5.83 cm), number of grains pod^-1 (5.53), grain yield (910 kg ha^-1), haulm yield (2287 kg ha^-1), Net return (₹54559 ha^-1) and BCR (2.63). The lowest values were obtained under control conditions.
