Abstract:
A field trial titled "Standardization of drip fertigation levels in mid-season Cauliflower (Brassica oleracea var. botrytis L.)" was conducted during the rabi season of 2018-2019 at the experimental farm of the Water Technology Centre, Indian Agricultural Research Institute, New Delhi. The experiment employed a randomized block design with four treatments: T₁ involved drip fertigation with 100% of the recommended dose of fertilizers as per schedule, T₂ utilized drip fertigation with 75% of the recommended dose, T₃ employed drip irrigation with 100% of conventional fertilizer applied to the soil, and T₄ served as the control with drip irrigation but without fertilizers. Each treatment was replicated five times. The outcomes revealed significant variations in parameters such as fresh curd weight, dry curd weight, net curd weight, and marketable curd weight, with the highest values observed in T₁, where 100% of the recommended fertilizers were used. The cauliflower's curd yield was notably higher in T₁, recording 27.88 tons per hectare. The treatment with 100% recommended dose (T₁) also exhibited the highest benefit-cost ratio at 2.8, emphasizing the economic viability of applying nutrients through drip fertigation to maximize cauliflower growth parameters and yield.
