The authors carried out the experiments in 1957 and 1958 to make clear the effects of the windbreak of Ogawara lake side on the climatic conditions and the growth of rice-plants. The results obtained were as follows
1. Wind velocity decreased within the range of distance of 10 times the height of windbreak.
2. Air temperature behind the windbreak became high in proportion to the amount of insolation.
3. When either Yamase-wind or westerly prevailed, wind velocity was mild and air temperature was high within the distance of 5 times the height of windbreak compared with the no windbreak area.
4. The yields of rice-plants increased within the distance of 5 times the height of windbreak, although the plants damaged by flood owing to the typhoon No. 22 in 1958. By the observations of the growing process, more luxuriant growth of the plants was observed within the distance of 10 times the height of windbreak.
