Abstract—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.

Index Terms—Eddy covariance technique, first ratoon cane, water use efficiency.
