Resumo: Cotton cropping has shifted from traditional southeastern Brazil producing zones to central region savannahs. In this process, significant changes in production technology as well as in the crop environment have occurred, concurrently with a great yield increase. These changes have disrupted the practice of fertilization, creating systems where intensive applications are made, although not properly supported by experimental data. This study aimed to evaluate, in field conditions, the effect of combined soil and foliar spray potassium doses on yield and quality of cotton fiber, in southeastern Goiás State. The trial was conducted in the municipality of Ipameri (16°35'S, 47°02'W, 920 m), during the 2004/2005 growing season. A randomized complete block with split-plot experimental design was used. Five doses were applied to soil (0 kg ha-1, 60 kg ha-1, 120 kg ha-1, 180 kg ha-1, and 240 kg ha-1 K2O), combined with four foliar doses (0 kg ha-1, 7.2 kg ha-1, 14.4 kg ha-1, and 21.6 kg ha-1 K2O). Yield gains were observed for potassium applied both through soil and foliar spraying, without interactions between modes of application. There were no effects of doses and mode of application on the technological cotton fiber quality. KEY-WORDS: Cotton fertilization; foliar-fertilization.

A cultura do algodoeiro no Brasil deslocou-se de zonas produtoras tradicionais da região Sudeste, para os cerrados da região central do país. Nesse processo ocorreram significativas mudanças na tecnologia de produção e no ambiente de cultivo, paralelamente a um grande incremento na produtividade. Essas alterações desorganizaram a prática da adubação, gerando sistemas com aplicações bastante intensivas, ainda não devidamente respaldados por dados experimentais. Este trabalho objetivou avaliar, em condições de campo, o efeito da combinação de doses de potássio aplicadas vias solo e foliar, sobre a produtividade e a qualidade da fibra do algodoeiro, nas condições do Sudeste do Estado de Goiás. O ensaio foi conduzido no município de Ipameri- GO (16°35'S, 47°02'W, 920 m), na safra 2004/2005. O delineamento experimental usado foi o de blocos completos casualizados, com parcelas subdivididas. Foram aplicadas cinco doses via solo (0 kg ha-1, 60 kg ha-1, 120 kg ha-1, 180 kg ha-1 e 240 kg ha-1 de K2O), combinadas com quatro doses foliares (0 kg ha-1; 7,2 kg ha- 1; 14,4 kg ha-1 e 21,6 kg ha-1 de K2O). Verificaram-se ganhos de produtividade em ambas formas de aplicação de potássio, não ocorrendo interações entre estas modalidades de aplicação. Não houve também efeitos significativos das doses e formas de aplicação sobre a qualidade tecnológica da fibra do algodoeiro.PALAVRAS-CHAVES: Algodão-nutrição; adubação foliarEscola de Agronomia - Universidade Federal de Goiás2007-10-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/1835Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 37, n. 2, Apr./Jun. 2007; 106-112Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 37, n. 2, abr./jun. 2007; 106-112Pesquisa Agropecuária Tropical; v. 37, n. 2, abr./jun. 2007; 106-1121983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/1835/1746Freitas, Roberto José deLeandro, Wilson MozenaCarvalho4, Maria da Conceição Santanainfo:eu-repo/semantics/openAccess2020-02-27T00:01:18Zoai:ojs.revistas.ufg.br:article/1835Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:54:52.553788Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
