A field experiment was conducted in Jorhat, Assam, India during 2000-01 to study the growth, yield and water use of broccoli cv. KTS-1 as affected by drip irrigation at different levels of evaporation replenishment (EPR; 60, 80, 100 and 120% of USWB class A pan evaporation), with or without black plastic mulch. A furrow irrigation at fortnightly intervals on the basis of available soil moisture depletion was included. There was improved growth, yield and increased water use efficiency under drip irrigation compared to furrow irrigation. The highest broccoli yield of 25.14 t/ha was found under drip irrigation at 120% EPR with black plastic mulch, while the lowest yield of 9.22 t/ha was recorded in the furrow-irrigated plants. The WUE was considerably higher under drip irrigation than under furrow irrigation. Drip irrigation at 60% EPR with black plastic mulch recorded the highest WUE (4.11 t/ha-cm), while the lowest WUE (0.59 t/ha-cm) was observed under furrow irrigation.
