Title: Interference of Red Rice (<i>Oryza sativa</i>) with Rice (<i>O. sativa</i>)
Abstract:Red rice ( Oryza sativa L. ♯ ORYSA) densities of 5, 108, and 215 plants/m 2 reduced grain yield of commercial rice ( Oryza sativa L.) 22, 77, and 82%, respectively. At a cultivated rice density of 195...Red rice ( Oryza sativa L. ♯ ORYSA) densities of 5, 108, and 215 plants/m 2 reduced grain yield of commercial rice ( Oryza sativa L.) 22, 77, and 82%, respectively. At a cultivated rice density of 195 plants/m 2 , red rice at 5, 108, and 215 plants/m 2 reduced straw dry weight of cultivated rice 18, 66, and 68%, respectively. At a red rice density of 5 plants/m 2 , reduction in number of cultivated rice grains per panicle ranged from 8 to 18%, whereas densities of 108 and 215 plants/m 2 reduced grains per panicle 56 to 70%. Red rice grain yield was 24 to 33% lower in ‘Mars' rice than in ‘Lebonnet’. Mars, a medium-grain cultivar that matures in 138 days, competed better with red rice than Lebonnet, a long-grain cultivar that matures in 126 days.Read More
