The crop used was a first ratoon Co 957, a non flowering late season sugarcane variety. The experiment was completely randomized following a one-factor design with 4 water deficit treatments in 3 replicates. It came out that the optimum water deficit treatment reached 20%, i.e., 80% of crop water requirements were satisfied through irrigation. That treatment gave 7.9 kg cane/m3 or 0.98 kg sugar/m3 as irrigation water use efficiency. Relatively low crop growth rates （0.2-0.4 cm/day） as well as low cane yields （24.5-78.4 t/ha） were obtained as a result of an intensive and persistent dry season occurred over the yield formation stage. In line of prevailing climatic conditions, cane juice quality measured was particularly high on Co 957 which used to be a moderately performing variety in Ferk6 2 sugar mill.展开更多
