A measurement of evaporation from the irrigated paddy field and absorption of water by the paddy rice

Abstract

Using the apparatus of Fig. 1, authors measured the amount of evaporation from the irrigated paddy field and absorption (≅transpiration) of water by the paddy rice in each growimg period 1953.These results are shown in Table 1 and Fig. 2. The absorption were few at first and reached to maximum in the beginning of young panicle formation. The evaportion in the paddy field were nearly equal to the evaporation at the observation field at first, but the former had been gradually less than the latter.
