Resumo: The aim of this research was to present ways to estimate the coefficient of soil heterogeneity from the intraclass correlation coefficient for different structure of experimental designs. The coefficient of soil heterogeneity estimates obtained by this method were compared with those obtained by the generalized least square method. Practically, there was no difference between the estimates obtained from both methods, and thus it is recommended to use the estimate obtained from the coefficient of intraclass correlation due to its simplicity and practicability. Several plot sizes were obtained from the coefficient of soil heterogeneity estimates, for different combinations of variation coefficient, replicate number, expected difference between treatments and significance level.

As estimativas dos coeficientes de heterogeneidade do solo obtidas por este método foram comparadas àquelas obtidas por meio de mínimos quadrados generalizados. Não houve diferenças entre as estimativas obtidas por ambos os métodos; nesse caso recomenda-se a estimativa com base no coeficiente de correlação intraclasse por ser mais simples e prática. Considerando-se o coeficiente de heterogeneidade do solo, obteve-se diversos tamanhos de parcela, para diferentes combinações de coeficiente de variação, número de repetições, grau de diferença que se espera detectar entre dois tratamentos e nível de significância.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlves, Sueli Martins de FreitasSeraphin, José Carlos2004-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6744Pesquisa Agropecuaria Brasileira; v.39, n.2, fev. 2004; 105-111Pesquisa Agropecuária Brasileira; v.39, n.2, fev. 2004; 105-1111678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6744/3800info:eu-repo/semantics/openAccess2014-07-02T17:30:40Zoai:ojs.seer.sct.embrapa.br:article/6744Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-02T17:30:40Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
