Resumo: This study was done on data of soil calibration curve and potassium analysis of flood rice soil. A completely randomized design was used with four levels of potassium: 0, 150, 300 and 450 kg/ha. The power test and regression coefficient were fixed to set up tables using SST and SSR to test linear hypothesis. Regression sum of square test was better than treatment sum of square in linear hypothesis, and it gave high signicant results. Fixed a desirable power test, this method provides a number of necessary replications to reach that power, this meaning substancial time and money economy.

Tratamentos e S.Q. Regressão Linear, a fim de se testarem hipóteses do tipo linear. Vê-se, nitidamente, que, para hipóteses lineares, a S.Q. Regressão Linear, quando comparada com a S.Q. Tratamentos, apresenta-se como um teste bem mais poderoso, oferecendo resultados altamente significativos. Desse modo, fixado um poder de teste desejável, obtém-se o número de repetições necessárias para se chegar a este poder, proporcionando uma economia substancial de tempo e dinheiro ao experimentador.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCarvalho, José Ruy Porto de2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16567Pesquisa Agropecuaria Brasileira; v.16, n.1, jan. 1981; 69-75Pesquisa Agropecuária Brasileira; v.16, n.1, jan. 1981; 69-751678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16567/10843info:eu-repo/semantics/openAccess2014-04-15T19:35:54Zoai:ojs.seer.sct.embrapa.br:article/16567Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:35:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
