Tolerance of Rice (Oryza sativa L.) and Echinochloa Weeds to Growth Suppression by Rice Straw Added to Paddy Soil in Relation to Iron Toxicity
The effects of addition of rice straw to submerged soil on the emergence and growth of rice (Oryza sativa L.) and two paddy weeds (Echinochloa oryzicola Vasing. and Echinochloa crus-galli (L.) Beauv. var. crus-galli) were investigated. Rice straw suppressed both the emergence and growth of transplan...
