Water Requirement and Irrigation Scheduling Through Drip Systems in Cabbage (Brassica oleracea var. capitata)

An experiment was conducted to study the water requirement and irrigation scheduling in cabbage (Brassica oleracea var. capitata). The treatment consisted of three irrigation levels viz. 100%, 80% and 60% on ET (Evapo-Transpiration) basis and three irrigation scheduling viz. daily, once in two days and once in three days in split plot design. It is revealed that significantly higher yield was noticed at 60% ET treatment (569.80q/ha during first year of trial) whereas, 80% ET treatment (703.82 and 488.40q/ha) during second and third year of trial as compared to 100% ET. At 60% ET, irrigation scheduling at once in two days was found significantly superior in the first year while 80% ET with irrigation scheduling once in two days during second and third year of trials with respect to daily and once in three days. Maximum water use efficiency was obtained under irrigation at 60% ET with once in two days (115.81q/ha??cm) irrigation treatment in the three consecutive years of experimentation. Irrigation at 80% ET with once in two days interval may be recommended for better yield and marketability in cabbage.
