Integrated nutrient management for black gram
|
Among organic manures, efficacy of vermicompost was found to be higher due to high nutrient status.

EXPERIMENTS WERE conducted at the Agricultural College and Research Institute, Madurai, to find out the combined effect of organic manure and inorganic fertilizers on the yield, quality of black gram and on soil fertility.
Five main plot treatments with no manure, Vermicompost at 1 and 2 t/ha and farm yard manure (FYM) at 1 and 2 t/ha along with eight subplot treatments involving 100 per cent of the recommended Nitrogen (N), Phosphorus (P) and Potassium (K) (25:50:0 Kg of N{-2}P{-2}O{-5} and k{-2}O/ha) and 75 per cent of the recommended levels in a split plot design were replicated twice. Vamban-1 black gram was grown as the test crop.
Yield results
The results showed that the black gram yields were significantly higher (1.03t/ha) in the treatments that received Vermicompost at 2t/ha plus 100 per cent of the recommended levels of N, P and K.
Significantly higher crude protein content of 18.5 per cent was recorded in the treatment that received Vermicompost at 2t/ha along with 100 per cent of the recommended levels of N, P and K as against the crude protein content of 14.7 per cent in the non-manured plots.
Among the two organic manures the efficacy of vermicompost was found to be higher due to high nutrient status and presence of cocoons.
