  • Competitive relationships between soybean cultivars and weeds were determined at different plant spacings and weed competition times. Soybean yields did not differ significantly between plant spacings. Annual weed competition more signficantly reduced yields and yield components of 'Williams' soybeans than those of 'Dongbuktae' and 'Suweon 83'. 'Suweon 83' and 'Dongbuktae' were more competitive to weeds than 'Williams'.
