The experiment on the effect of shelter-hedge for the growth of uplandrice against typhoon was carried out at summer, 1955. The hedge whose height was 250cm was made from woods round by sweetpotato stems, and the screening ratio was 80%.
The results obtained is as follows;
(1) The half velocity zone reached at about 7 times the hedge height.
(2) At the above zone the soil temperature was a few heigher than at the standard zone and the yield was also superior.
