Resumo: | A field experiment was conducted in Sapezal, Mato Grosso state, Brazil, in 2007/2008, with the purpose of determining the effect of potassium sources on yield components, yield, fiber quality and economical aspects of cotton (Gossypium hirsutum L.). A randomized complete block experimental design was used, with five replications. The treatments consisted of application in covering, via soil, at rate of 100 kg ha-1 of K2O, in two split applications, of the sources KCl, K2SO4, KNO3 and K2SO4.2MgSO4. The number of nodes, height, number of bolls in the superior third and the weight of boll in the medium third was higher with K2SO4.2MgSO4 than with KNO3 source. The potassium fertilizers did not influence the fiber revenue, but the fertilizing with K2SO4.2MgSO4 source had higher cotton seed yield and lint yield, although the uniformity ratio of fibber and profitability were smaller in relation to K2SO4. The fibber agio index was higher with KNO3 source. The production cost was higher with K2SO4.2MgSO4 source and in function of the smallest production cost, KCl source presented superior liquid revenue than other treatments. |

O delineamento utilizado foi o de blocos casualizados, com cinco repetições. Os tratamentos constaram da aplicação em cobertura via solo na dose de 100 kg ha-1 de K2O, parcelada em duas aplicações, nas fontes KCl, K2SO4, KNO3 e K2SO4.2MgSO4. O número de nós, a altura da planta, o número de capulhos no terço superior e o peso do capulho no terço médio foram maiores no tratamento com K2SO4.2MgSO4, em relação ao KNO3. Os adubos potássicos não influenciaram o rendimento de fibra, mas a adubação potássica de cobertura na fonte K2SO4.2MgSO4 mostrou-se superior em termos de produtividade de algodão em caroço e em pluma, apesar da uniformidade do comprimento da fibra ser menor em relação ao K2SO4. O índice de ágio da pluma foi maior na fonte KNO3. O custo de produção foi mais elevado na fonte K2SO4.2MgSO4 e em função do menor custo de produção, o KCl apresentou receita líquida superior aos demais tratamentos.UEL2009-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/465010.5433/1679-0359.2009v30n4Sup1p1135Semina: Ciências Agrárias; Vol. 30 No. 4Sup1 (2009); 1135-1144Semina: Ciências Agrárias; v. 30 n. 4Sup1 (2009); 1135-11441679-03591676-546Xreponame:Semina.
