—The propose of this study is to evaluate water use
of the first ratoon cane. First ratoon cane was produced at Cane
and Sugar Industry Promotion Center Region 1 from June 2010
to April 2011. To evaluate crop water use Eddy Covariance
technique was used. From the results, water use of first ratoon
cane was gradually increased from predawn and reach the
maximum during 12:00-14:00 and then water use was
decreased. Moreover, water use in each growing stage were
found. Minimum of water use average about 1.6 mmd-1 was
found in germination stage, while maximum water use is 2.4
mmd-1 was found in stalk elongation stage. In addition, total
water use germination stage, tillerling stage, stalk elongation
stage and maturity stage was 57.3, 151.3, 330.6 and 142.7 mm,
respectively. However, total water use of first ratoon cane was
682.1 mm. Water Use Efficiency of 1st ratoon cane was 0.012
tyield/tH2O. For this study we can concluded that water use of
first ratoon cane depend on daily time and growing stage and
total water use was 682.1 mm.
