Resumo: The aim of this work was to determine the effects of fertirrigation with potassium and black polyethylene cover on tomato. A field experiment was carried out on a cambic yellowish podzolic at the Universidade Federal de Viçosa, in Viçosa, MG, Brazil. The treatments, with five replicates, following a randomized block design, were: (A) manual application of 40% of recommended K rate at the seedling transplantation row and manual sidedress application of 60%; (B) manual application of 40% of recommended K rate at the seedling transplantation row and 60% by fertirrigation; (C) similar procedure to B but with black polyethylene cover; (D) application of 100% of K rate by fertirrigation and (E) similar procedure to D but with black polyethylene cover. Treatments B, C, D and E were drip irrigated. Tomato yields were higher with K application by fertirrigation than using the manual fertilization method, but the tomato yields were not influenced by K partial or total fertirrigation neither by black polyethylene cover. The NO3--N, organic-N, K, Ca and Mg concentrations on leave petioles were not influenced by treatments.

O experimento foi realizado na Universidade Federal de Viçosa, em solo Podzólico Vermelho-Amarelo câmbico. Os tratamentos, em cinco repetições, no delineamento em blocos casualizados, corresponderam a: (A) aplicação manual de 40% da dose recomendada de K no sulco de transplante e 60% aplicados manualmente, em cobertura; (B) aplicação manual de 40% da dose de K no sulco de transplante, e 60% aplicados por fertirrigação; (C) procedimento idêntico ao anterior, porém com o solo coberto por plástico preto;(D) aplicação de 100% da dose de K por fertirrigação e (E) procedimento idêntico ao anterior, porém com o solo coberto por plástico preto. Os tratamentos B, C, D e E foram irrigados por gotejamento. Maiores produções de tomates foram obtidas com a aplicação do K por fertirrigação do que com a aplicação manual. Estas produções, entretanto, não foram influenciadas pela aplicação total ou parcial de K por fertirrigação, nem pela presença de cobertura plástica do solo. Os teores de N-NO3-, N-orgânico, K, Ca e Mg no pecíolo do tomateiro não foram influenciados pelos tratamentos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSampaio, Regynaldo ArrudaFontes, Paulo Cezar RezendeSediyama, Carlos Sigueyuki1999-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5141Pesquisa Agropecuaria Brasileira; v.34, n.1, jan. 1999; 21-30Pesquisa Agropecuária Brasileira; v.34, n.1, jan. 1999; 21-301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5141/2333info:eu-repo/semantics/openAccess2010-07-14T13:37:06Zoai:ojs.seer.sct.embrapa.br:article/5141Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-14T13:37:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
