Abstract

Competition studies in field trials were conducted between common purslane (Portulaca oleracea L.) and table beets (Beta vulgaris L., var. Detroit Red) and between common purslane and snap beans (Phaseolus vulgaris L., var. Eastern Butter). Common purslane control was most critical during the first 2 weeks after beet and bean emergence. Common purslane control for longer than 2 weeks did not increase beet or bean yields. The longer common purslane was allowed to compete after beet or bean emergence, the more yields were decreased. Common purslane was a stronger competitor in beets than in beans. The faster and taller-growing bean plants provided more competition than did beets. Cultivation between rows until lay-by increased both beet and bean yields.
