Resumo: Maize has economic importance for the State of Santa Catarina mainly due to the presence of pig and poultry farms.Therefore a study was conducted during the harvest season of 2009/2010 and 2010/2011 in Chapecó, SC , with the objective ofevaluating the effect of plant arrangement on the stalk rot (PBC) and damaged kernels (GA) using the spacings 0.4, 0.6 and 0.8m between rows. In the main plot three corn hybrids of early cycle (P30F36 , AS 1575, Maximus) were tested, the spacing in theplots and nitrogen levels 0 , 75 , 140 , 210 and 290 kg/N/ha in the sub-plots, using four replicates per treatment. Levels of PBCwere evaluated, and also weight of thousand grains, grain yield, percentage of GA and the incidence of Fusarium verticillioidesin corn kernels. Hybrids AS 1575 and P30F36 have reduced the incidence of PBC with increased spacing. Significant differencein grain yield in hybrids and interaction between N doses were observed in the different spacings. The percentage of GAshowed significant difference for the mean of hybrids.

Diante disso, um estudo foi realizado nas safras 2009/10 e 2010/11 em Chapecó, SC, com o objetvo de avaliar o efeito do arranjo de plantas sobre as podridões do colmo (PBC) e grãos ardidos (GA), utlizando os espaçamentos de 0,4, 0,6 e 0,8m entre linhas. Na parcela principal foram testados três híbridos simples de milho de ciclo precoce (P30F36, AS 1575 e Maximus), nas subparcelas os espaçamentos e nas divisões das subparcelas as doses de nitrogênio 0, 75, 140, 210 e 290kg ha-1 de N usando quatro repetções por tratamento. Foram avaliados os níveis de PBC, a massa de mil grãos, o rendimento de grãos, a percentagem de GA e a incidência de Fusarium vertcillioides nos grãos de milho. Os híbridos AS 1575 e P30F36 apresentam redução na incidência de PBC com o aumento do espaçamento entre linhas. Ocorreu diferença signifcatva no rendimento de grãos na interação híbridos e doses de N entre espaçamentos. A porcentagem de GA apresentou diferença signifcatva para a média de híbridos.
