Abstract
Rough-rice yield of drill-seeded paddy rice (Oryza sativa L. ‘Lebonnet’ and ‘Starbonnet’) at stands of 215 to 270 plants/m2 at Stuttgart, Arkansas were reduced 18% by season-long competition of spreading dayflower (Commelina diffusa Burm. f. ♯3 COMDI) at a density of 22 plants/m2. Competition durations of 20, 40, 60, or 80 days did not reduce rice yields. None of the durations of competition affected head-rice yields (percent whole milled kernels) or germination of rice seed.Keywords
