摘要：An experiment on cauliflower was carried out at Water Technology Centre, Rajendranagar, Hyderabad, Telangana during rabi 2019-2020. Experiment was laid out in split plot design with nine treatments consists of three drip irrigation levels (0.6, 0.8 and 1.0 Epan) as main plots and three NK fertigation levels (Control, 40:50 and 80:100 kg N and K2O ha-1) as subplots. The results revealed that drip irrigation at 1.0 EPan recorded significantly higher curd yield ( 18.7 t ha-1) followed by 0.8 EPan ( 17.1 t ha-1) and lower curd yield ( 15 t ha-1) was obtained at 0.6 EPan. Fertigation at 80:100 kg N - K2O ha-1 recorded significantly higher curd yield (23.8 t ha-1) than 40:50 kg N - K2O ha-1 (19.7 t ha-1) and lower curd yield (7.2 t ha-1) was obtained in control treatment. Higher water productivity (9 kg m-3) of cauliflower recorded at lower drip irrigation regime of 0.6 Epan than 0.8 (8 kg m-3) and lower water productivity (7.2 kg m-3) recorded at higher drip irrigation regime of 1.0 Epan. It was recommended that scheduling of drip irrigation at 1.0 Epan and fertigation scheduled at 80:100 kg N - K2O ha-1 to obtain higher curd yield where as high water productivity was observed in drip irrigation regime of 0.6 Epan.
