Resumo: With the objective of studying the effect of increasing phosphorus and potassium doses on the agronomical and technological characteristics of the cotton (Gossypium hirsutum L.), cultivar IAC 20, an experiment was carried out during 1994/95 on a Red-Dark Latossol at the Embrapa-Centro de Pesquisa Agropecuária do Oeste (CPAO) in Ponta Porã, MS, Brazil. A randomized bloch design was used in a 3 x 5 factorial arrangement with four replications. The doses were 30, 60 and 90 kg ha-1 of P2O5, applied as triple superphosphate, and 0, 30, 60, 90 and 120 kg ha-1 of K2O as KCl. The K2O doses used had a significant influence on the seed cotton yield, plant height and weight of 100 seeds and of bolls.

IAC 20, foi conduzido um experimento em 1994/95, num Latossolo Vermelho-Escuro do Campo Experimental da Embrapa-Centro de Pesquisa Agropecuária do Oeste (CPAO), em Ponta Porã, MS. O delineamento experimental foi o de blocos ao acaso, num esquema fatorial 3 x 5, com quatro repetições. As doses foram de 30, 60 e 90 kg ha-1 de P2O5, na forma de superfosfato triplo; 0, 30, 60, 90 e 120 kg ha-1 de K2O, na forma de KCl. Somente as doses de K2O influenciaram significativamente o rendimento de algodão em caroço, a altura da planta e o peso de 100 sementes e dos capulhos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraStaut, Luiz AlbertoAthayde, Manoel Luiz Ferreira1999-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5512Pesquisa Agropecuaria Brasileira; v.34, n.10, out. 1999; 1839-1843Pesquisa Agropecuária Brasileira; v.34, n.10, out. 1999; 1839-18431678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5512/2703info:eu-repo/semantics/openAccess2012-02-13T11:38:31Zoai:ojs.seer.sct.embrapa.br:article/5512Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-02-13T11:38:31Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
