This experiment is conducted to see the alteration in calculation of amount of duty of water in paddy fields, by the miraculous rice TONG-IL(IR667) made its appearance to us, therefore results obtained were summarized as follow. 1. In comparison with depth of evapo-transpiration and evaporation in the evaporator, the ratio is ET/V=1.84 in clay loam and ET/V=2.00 in loam, the value is larger than any vairety. 2. Comparison by growing periods of rice plants growing period 5 and Ear for mation stage (primor stage) 6 ET/V value grow larger from 3.30 to 3.77. 3. Transpiration ratio is 260.4 in clay loam and 275.0 in loam, two value are less than 300.
