Resumo: This research aimed evaluates the influence of purple nutsedge (Cyperus rotundus) on the agronomic performance of maize. We conducted a field experiment at Viçosa, MG, in completely randomized design experimental with three replications. The treatments consisted of the interaction of maize with nine nutsedge densities (0, 10, 30, 50, 90, 110, 130, 160 and 260 plants m-2). In the flowering culture was made the measurement of plant height, the insertion of the corn ears and the total dry matter of corn plants. At harvest were determined ear weight, grain yield and 100-grain weight adjusted to 13% moisture. Higher density of nutsedge increased plant height and the insertion of the first corn ear. We also observed a reduction in total dry matter accumulation, ear weight, 100-grain weight and grain yield in all densities evaluate. Nutsedge control, even at low densities is necessary because the presence of this plant promotes negative effect on growth and development of corn with a direct consequences on crop productivity.

O experimento de campo foi realizado sob o delineamento experimental inteiramente ao acaso, com três repetições. Os tratamentos foram constituídos do convívio do milho com nove densidades de tiririca (0, 10, 30, 50, 90, 110, 130, 160 e 260 manifestações epígeas m-2). No florescimento da cultura fez-se a medição da altura das plantas, da inserção das espigas e a massa seca total das plantas de milho. Por ocasião da colheita foram determinados a massa de espigas, o rendimento de grãos e a massa de 100 grãos. O incremento da densidade de tiririca aumentou a altura de plantas e de inserção da primeira espiga do milho. Observou-se também redução no acúmulo de massa seca total, na massa de espigas e de 100 grãos e na produtividade do milho em todas as densidades avaliadas. A interferência da tiririca reduz o crescimento do milho com consequências diretas na produtividade de grãos da cultura.UEL2015-10-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1599310.5433/1679-0359.2015v36n5p3077Semina: Ciências Agrárias; Vol. 36 No. 5 (2015); 3077-3084Semina: Ciências Agrárias; v. 36 n. 5 (2015); 3077-30841679-03591676-546Xreponame:Semina.
