The treatment T100 consumed 1491.75 and
1701.13 mm of water in 2006/07 and 2007/08
cropping seasons, respectively, while the treatments
T50, T25, and T0 consumed 1100.50 and
1097.19 mm; 856.21 and 792.57 mm and 729.25
and 751.13 mm, respectively, in the two cropping
seasons. For the two cropping seasons, the
values of water use efficiency ranged from 4.58 to
18.87 kg/ha (Table 6). The percentage of total
water applied from the total water use ranged
from 14.83 to 61.72% for the seasons. Also, the
fractional increase in water use efficiency demonstrated
the highest value of 2.02 in 2006/07 and
the lowest value of 0.30 in 2007/08 for the two
seasons (Table 6).
