Nutrient Uptake Studies under Varying Drip Irrigation Regimes and Fertigation Levels in Rabi Cauliflower in Telangana State
International Journal of Plant & Soil Science,
A field study was conducted with different drip irrigation regimes and NK fertigation levels on cauliflower at Hyderabad, Telangana during rabi 2019-2020. The experiment was laid out in a split plot design with three drip irrigation regimes viz., 0.6, 0.8 and 1.0 Epan as main plots and three drip NK fertigation levels of control (N0K0), 50 % recommended dose of NK (N40 K50) and 100 % recommended dose of NK (N80 K100) as sub plots altogether nine treatments and replicated thrice. Drip irrigation scheduled at 1.0 Epan recorded significantly higher curd yield (18.7 t ha-1) than 0.8 Epan (17.1 t ha-1) and 0.6 Epan (15.0 t ha-1). NPK and S uptake were significantly higher in irrigation scheduled at 1.0 Epan than 0.8 and 0.6 Epan during all stages except at 30 DAT and harvest where S uptake was found to be non significant among different irrigation levels. Drip fertigation at 100 % recommended dose of NK recorded significantly higher curd yield (23.8 t ha-1) than 50 % recommended dose of NK (19.7 t ha-1) and N0K0 (7.2 t ha-1). Drip NK fertigation levels significantly increased the NPK and S uptake with each increment in NK fertigation level from N0K0 to 100 % recommended dose of NK at all stages.
