Studies on the effect of integrated nutrient management practices on the growth and yield of cauliflower (Brassica oleracea var. botrytis L.)

Abstract

The study was carried out at the Research farm of Abhilashi University, Mandi (H.P) during the winter season 2023-24. The experiment was laid out in Randomized Block Design comprising of seven treatments with three replications. The treatments were T1 N: P: K (100%), T2 Farm Yard Manure (100%), T3 Poultry Manure (100%), T4[N: P: K (50%) + Farm Yard Manure (50%)], T5[N: P: K (50%) + Poultry Manure (50%)], T6[N: P: K (50%) + Farm Yard Manure (25%) + Poultry Manure (25%)] and T7 (Control). The results showed that treatment T5 recorded maximum plant height (51.65 cm), leaf length (47.68 cm), leaf width (23.68 cm), days required for curd initiation (62.43 DAT), curd diameter (14.93 cm), curd weight (878.77 g), yield per plot (7.91 kg) and yield per hectare (292.95 q/ha). Similarly in terms of economics maximum gross income (₹ 5,27,304), net income (₹ 4,14,266) and (3.66) B: C ratio were recorded under treatment T5. Therefore, T5 appeared to be the best for achieving the higher growth, yield and economic benefit of cauliflower.
