The water use efficiency was 18.87 and 9.02 kg/ha/mm in T100 with 51.11% and 61.72% of total applied water from total water use, in the two cropping seasons. T25 revealed the least water use efficiency and percentage of applied
water from total water use. A higher fractional increase in water use efficiency was also recorded in T100 (Table 6). These results are in conformity with the findings of Mohammed et al. (2006) in cassava production.
