Resumo: | Currently, the cultivation of the cotton plant is based on a scale production model, characterized by high yields and intensive use of fertilizers, agrochemicals and mechanization. The objective of this study was to evaluate the influence of different row spacings on cotton crops, with or without growth regulator, and their effects in crop development and yield. The experimental design was in completely randomized blocks, in a 3x3 factorial scheme with 4 replications, using three row spacings: 0.45, 0.70 and 0.90 m. Three growth regulator conditions were tested: a) application split into four stages, b) single application at 70 d.a.e, and c) no regulator application. The project was conducted in the city of Selvíria, Mato Grosso do Sul state, in November 2005. It was verified that the application of growth regulator is efficient in the limitation of plant height. The highest yield and boll mass was found in the split application of the regulator. The number of bolls and reproductive branches per plant was higher in the wider row spacings. |

Objetivou-se, com este trabalho, avaliar a influência de diferentes espaçamentos de cultivo, submetidos ou não à aplicação de regulador de crescimento, no desenvolvimento e na produtividade do algodoeiro. O delineamento experimental foi de blocos casualizados, em esquema fatorial 3x3, com nove tratamentos e quatro repetições, constituído por três espaçamentos: 0,45, 0,70 e 0,90 m entre linhas; regulador de crescimento: a) aplicação parcelada em quatro etapas; b) aplicação única aos 70 d.a.e.; e c) sem a aplicação do regulador. O projeto foi instalado no município de Selvíria (MS), em novembro de 2005. De posse dos resultados, verificou-se que a aplicação de regulador vegetal é eficiente em termos de limitação do crescimento em altura. A maior produtividade aliada a maior massa de capulhos foram encontradas em aplicação do regulador de forma parcelada em comparação à não-utilização do produto, para a cv Deltaopal. O número de capulhos e de ramos reprodutivos, por planta, foi maior nos maiores espaçamentos.Universidade Estadual de Maringá2008-05-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/354610.4025/actasciagron.v30i3.3546Acta Scientiarum.
