Effect of Integrated Nutrient Management on Growth, Yield Attributes, Yield and Economics of Off-season Cauliflower (Brassica oleracea var. Botrytis L.) Grown under North Eastern Ghat Zone of Odisha

The experiment was conducted during 2019 (July-October) at farmer’s field in Kandhamal district of Odisha under Krishi Vigyan Kendra, Kandhamal, Zone-V, Kolkata, OUAT, Bhubaneswar, Odisha, India to study the effect of integrated nutrient management on growth, yield attributes, yield and economics of off-season cauliflower (Brassica oleracea var. Botrytis L.). The experiment was laid out in Randomized Block Design (RBD) consisted of four treatments with seven replications. The treatments comprised of T₁: Farmer’s practice (FYM @ 1 t ha^-1 and fertilizer @ 60–40-30 kg N-P₂O₅K₂O ha^-1), T₂: 100% RDF @120:60:60 kg N-P₂O₅ K₂O ha^-1, T₃: Soil test based NPK+FYM @ 5 t ha^-1 and T₄: Soil test based NPK+FYM @ 5 t ha^-1+Boron. From the experiment it was found that integrated application of chemical fertilizers as per soil test results, organic manures (FYM @ 5 t ha^-1) and micronutrient (boron) was the best option for achieving better yield. The highest plant height (57.3 cm), number of leaves plant^-1 (22.7), leaf length (35.6 cm), curd yield (188.4 q ha^-1), marketable curd weight (635.4 g), net return (₹ 1,48,260 ha^-1) and B C ratio (1:3.2) were recorded with the treatment T₄ followed by and T₂. Whereas, the lowest values of growth parameters like plant height (40.7 cm), number of leaves plant^-1 (16.2), leaf length (26.1 cm), curd yield (140.2 q ha^-1), marketable curd weight (466.8 g), net return (₹ 1,01,130 ha^-1) and B C ratio (1:2.7) were recorded with the treatment T₁.
