Irrigation studies on developing production functions for cauliflower

Scheduling of irrigation at 1.2 ETc recorded significantly higher growth, yield attributes and yield of cauliflower which was at par with 1.0 ETc irrigation regime. Application of irrigation at 0.6 ETc recorded significantly higher and maximum water use efficiency (224.33 kg ha⁻¹-mm) than rest of the irrigation regimes. The quadratic production function (R²=0.99) was computed to find out the predicted yield in a given irrigation regime.
