Última Effect of plant row spacing and herbicide use on weed aboveground biomass and corn grain yield Planta Daninha Acciares,H.A.; Zuluaga,M.S.. The use of narrow plant spacing in corn (Zea mays) has been suggested as a technological alternative to obtain grain yield increases, due to a better use of resources. The regular pattern could diminish intraspecific competition while favoring interspecific competition with weeds. The objective of this study was to analyze the effect of corn row spacing on weed aboveground biomass and corn grain yield. Field experiments were conducted during 2002/2003 and 2003/2004 growing seasons. Three corn hybrids with two-row width (0.70 and 0.35 m) were tested. A greater photosynthetic photon flux density (PPFD) interception with a lower weed aboveground dry matter in narrow row arrangement was obtained. Corn grain yield was greater in the narrow row arrangement than... Tipo: Info:eu-repo/semantics/article Palavras-chave: Weed cultural control; Row arrangement; Natural weed populations.
