Resumo: | A 'blank experiment' was designed at the Centro Nacional de Pesquisa de Hortaliças (CNPH), Brasília, DF, to estimate the optimum size of experimental plots in potato (Solanum tuberosum L.) trials. The cultivar 'Bintje' was used, in a 0,80 x 0,30 m spacing. Sixteen rows of 112 plants were harvested on an individual plant basis. The coefficient of soil heterogeneity proposed by Smith was estimated according to Hatheway & Williams, and the plot sizes were estimated by Hatheway's method. Results are presented in graphs as a function of the number of blocks, of the true differences to be detected, and of the types I & II errors, for experiments with various treatment numbers. The ideal plot size is chosen for each situation, as function of the parameters enumerated above. |

Utilizou-se a cultivar Bintje plantada em espaçamento de 0,80 m por 0,30 m. Foram colhidas 16 fileiras com 112 plantas cada uma. O coeficiente de heterogeneidade de solo proposto por Smith foi estimado segundo o método proposto por Hatheway & Williams e os tamanhos de parcela estimados pelo método proposto por Hatheway. Os resultados são apresentados através de gráficos em função do número de blocos, das verdadeiras diferenças que se deseja detectar e das probabilidades associadas aos erros tipo I e II para experimentos com diversos números de tratamentos. O tamanho de parcela adequado é escolhido para cada situação em função dos aspectos enumerados acima.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCordeiro, Célia Maria TorresMiranda, João Eustáquio Cabral deCampos, Jarbas2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16286Pesquisa Agropecuaria Brasileira; v.17, n.9, set. 1982; 1341-1348Pesquisa Agropecuária Brasileira; v.17, n.9, set. 1982; 1341-13481678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/16286/10481info:eu-repo/semantics/openAccess2014-04-16T16:39:48Zoai:ojs.seer.sct.embrapa.br:article/16286Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T16:39:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
