Abstract

Rough-rice yield of drill-seeded paddy rice (Oryza sativaL. ‘Lebonnet’ and ‘Starbonnet’) at stands of 215 to 270 plants/m2at Stuttgart, Arkansas were reduced 18% by season-long competition of spreading dayflower (Commelina diffusaBurm. f. ♯3COMDI) 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.
