Resumo: Two levels of nitrogen and potassium were combined with drip irrigation system under edaphoclimatic conditions of "cerrado" soil in central Brazil to test their effect on the yield of 'Kada' tomato (Lycopersicum esculentum Mill). The water head was of 0.8, 1.0 and 1.2 levels of the class A evaporation tank settled on bare soil. Results showed no significant difference among treatments for the total fruit production per hectare. On the other hand, production of large fruits was different among treatments. It was observed that higher level of ammonium sulfate increased number and weight of fruits showing "blossom end rot", independently of the water head used. The combination of 0.8 water level with 1.400 kg/ha of ammonium sulfate and 918 kg/ha of potassium cloride proved to be the most effective in water utilization.

Aplicaram-se lâminas de irrigação correspondentes a 0,8, 1,0 e 1,2 da evaporação de um tanque classe A instalado sobre solo nu. Verificou-se não haver diferenças significativas entre tratamentos na produção total de frutos por hectare; entretanto, a produção de frutos graúdos diferiu entre os tratamentos estudados. Doses elevadas de sulfato de amônio aumentaram o número e o peso dos frutos com podridão estilar independentemente da lâmina de irrigação aplicada. A menor lâmina de irrigação combinada com as doses de 1.400 kg/ha de sulfato de amônio e 918 kg/ha de cloreto de potássio apresentaram melhor eficiência do uso de água.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraOliveira, Carlos A.S.Carrijo, Osmar A.Olitta, Antonio F.L.Reis, Neville V.B. dosFontes, Ruy R.2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16870Pesquisa Agropecuaria Brasileira; v.16, n.2, fev. 1981; 259-263Pesquisa Agropecuária Brasileira; v.16, n.2, fev. 1981; 259-2631678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16870/11199info:eu-repo/semantics/openAccess2014-04-15T19:39:04Zoai:ojs.seer.sct.embrapa.br:article/16870Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:39:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
