Description
The result of this experiment proved that percentage of injured ears by stem-maggot in rice varied in the same variety on account of different planting ways whether one variety was planted in bulk or planted in a row variety by variety. And varieties of little tillers showed higher percentage in the former than in the latter, on the other hand ones of many tillers showed vice versa. The amounts of layed eggs in August had taken good accordance with these tendencies.
