Productivity and profitability of black gram as influ-enced by nutrient management under organic farming

A field experiment was conducted at research farm, Department of Agronomy, JNKVV, Jabalpur (M.P.) during, kharif season of 2016. A set of five organic nutrient management [NM1 (100% nitrogen through FYM), NM2 (100% nitrogen through vermicompost), NM3 (50% nitrogen through FYM + 50% nitrogen through vermicompost + PSB @3 ml/l), NM4 (25% nitrogen through FYM + 25% nitrogen through vermicompost + Rhizobium +PSB @5ml/l) and NM5 (control)] were tested in Randomized Block Design with four replications. An organic nutrient management practices showed significant (p=0.05) effect on plant height, primary branches, total dry matter of black gram crop. The results revealed that yield attributing characters and yields were significantly influenced by the application of different organic nutrient management. Among the organic nutrient management, NM4 produced significantly higher pods per plant (20.67) and seeds per pod (7.93) as well as seed yield (419.90 kg/ha) in black gram. The minimum values of yield attributes and yield were observed under NM5 (control). The GMR, NMR and B: C in black gram were maximum under NM4 (Rs 39332/ha, Rs 15392/ha and 1.64 respectively) and the values for Gross monetary returns, Net monetary returns and B: C were minimum (Rs 20585/ha, Rs 2005/ha and 1.11, respectively) under NM5.
