内容記述（抄録等）
The present studies were carried out to obtain a data about the quota of the time of day, which was one of the most important problems on the occasion of joint irrigation.
1. With the beans, three experiment plots were arranged and were irrigated by spinkler respectively. The 1st plot was sprinkled in the early morning (6.00) only the 2nd plot was in the daytime (12.00) only and the 3rd plot was in the evening (18.00) only through all over the plant life.
2. In point of yield, the early morning plot was excellent. The daytime plot and the evening plot was 73% and 72% respectively to the early moinlng plot.
3. On the irrigation efficiency of sprinkling, the early morning plot was superior and the daytime plot was inferior to others. But the irrigated water was utillzed effectively by the plant in the daytime plot.
