In order to develop a weed control technology for the narrow-row dense cultivation of adzuki beans widely practiced in Kyoto Prefecture, we investigated the effects of mechanical weeding against weeds and adzuki beans using a weeding cultivator widely used for young wheat and barley leaf cultivation. In the weed survey conducted after weeding by the weed cultivator in this study, residual weeds were mostly observed between the plants, mainly in the seeding rows. Weeds in the plots with two or three times of mechanical weeding tended to be suppressed compared with those in the plots with single mechanical weeding, suggesting that mechanical weeding should be conducted several times during the adzuki bean cultivation period. However, the number of pods per plant decreased with the frequency of mechanical weeding treatments, suggesting that mechanical weeding by the cultivator negatively affected adzuki bean yield-related traits.
