Resumo: | A two-year field study 1980 and 1981 at the Centro Nacional de Pesquisa de Hortaliças in Brasília, DF., Brazil, was carried out on a Red-Latosol clay soil, envolving five levels (0, 2, 4, 6 and 8 t/ha) of 4-14-8 commercial fertilizer mixture and three potato cultivars (Achat, Aracy and Bintje). The experimental design was a randomized block, with four replications, in a 5 x 3 factorial arrangement. The yield of marketable tubers, cultivars and the combinations of these two factors have shown statistically significant differences. The yield for each year and cultivar combination presented a good fit using Mitscherlich's equation. The best technological alternatives in terms of profit and risk were selected using stochastic dominance rules for each cultivar and among these cultivars. |

O delineamento experimental foi o de blocos casualizados, distribuídos em um fatorial 5 x 3, com quatro repetições. A análise da variância da produção comercial revelou diferenças estatisticamente significativas para doses, cultivares e interação destes dois fatores. A equação de Mitscherlich apresentou um ajustamento satisfatório às produções de cada uma das combinações de ano e cultivar. Utilizou-se a técnica de dominância estocástica para a escolha das alternativas tecnológicas mais eficientes, sob o ponto de vista de rentabilidade e risco, por cultivar entre várias doses de adubação e entre cultivares.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCrisostomo, Lindbergue AraujoCampos, Tarcísio Gomes da SilvaCordeiro, Célia Maria TorresCastor, Otoniel Soares2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15187Pesquisa Agropecuaria Brasileira; v.18, n.3, mar. 1983; 205-212Pesquisa Agropecuária Brasileira; v.18, n.3, mar. 1983; 205-2121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15187/9007info:eu-repo/semantics/openAccess2014-04-16T18:53:51Zoai:ojs.seer.sct.embrapa.br:article/15187Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:53:51Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
