Description

Response of cabbage to different formulated irrigation schedules under mulch and non-mulch condition using calibrated AquaCrop model was evaluated. The formulated alternative delivery schedules were optimized based on water use efficiency. Simulations were carried out for the period 27th November 2013 to 19th February 2014. The model provided excellent simulation of canopy and yield. The harvest index was observed as 80% for cabbage.Schedule S8 (mulch + Irrigation schedule at 80% ETc) saved 25.19% water with only 4.63% reduction in the yield of cabbage head compared to control and resulted in water use efficiency as 6.05 kgm-3.Thus S8 is recommended to be used for cabbage production, to water productivity.
