In 1953, experiments were performed as a part of the fundamental works for the purpose of setting a weeding system in field management. After perfect weeding at the time of sprouting potato plants were subjicted to 10 conditions differently controlled by weeding and cultivating in different periods in growth, and the influence of the weed volumes at the harvest time on the crop yields were examined. The weed volumes varied according to the conditions of the treatment. The yield of potato, however, seemed not to be influenced. Any correation between the weed volume and the yield were not remarked. In this experiment, the maximum weed volume was about 3 kg per. 1m<SUP>2</SUP> and the yield of potato was about 1500 kg per 10a.
