Resumo: The objective of this work was to determine the effect of the basic experimental unit size (BEU) on the optimum plot size estimation for the evaluation of forage turnip (Raphanus sativus) fresh matter weight. Data from fresh matter weight of 3,456 BEUs of 0.5×0.5 m (0.25 m2) were used, and 36 BEU plans, with sizes from 0.25 to 16 m2, were formed. For each BEU plan, the optimum plot size was determined by the method of maximum curvature of the coefficient of variation model. The least significant difference was calculated by Tukey’s test in 2,016 scenarios formed by the combinations of 36 optimum plot sizes (one for each BEU plan), i treatments (i = 5, 10, 15, and 20), and r replicates (r = 3, 4, 5, 6, 10, 15, and 20), considering both the completely randomized designs and the complete block ones. Optimum plot size depends on the size of the basic experimental unit. In uniformity trials with forage turnip, the evaluation of fresh matter weight should be done in basic experimental units with the smallest possible size.

Dados de massa de matéria fresca de 3.456 unidades experimentais básicas de 0,5×0,5 m (0,25 m2) foram utilizados, tendo-se formado 36 planos de UEBs com tamanhos entre 0,25 e 16 m2. Para cada plano de UEB, determinou-se o tamanho ótimo de parcela, pelo método da curvatura máxima do modelo do coeficiente de variação. A diferença mínima significativa pelo teste de Tukey foi calculada para 2.016 cenários, formados pelas combinações entre 36 tamanhos ótimos de parcela – um para cada plano de UEB –, i tratamentos (i = 5, 10, 15 e 20) e r repetições (r = 3, 4, 5, 6, 10, 15 e 20), tendo-se considerado tanto os delineamentos inteiramente casualizados como os de blocos ao acaso. O tamanho ótimo de parcela depende do tamanho da unidade experimental básica. Em ensaios de uniformidade com nabo‑forrageiro, a avaliação da massa de matéria fresca deve ser feita em unidades experimentais básicas com o menor tamanho possível.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Cargnelutti Filho, AlbertoStorck, LindolfoLúcio, Alessandro Dal’ColToebe, MarcosAlves, Bruna Mendonça2016-07-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/21375Pesquisa Agropecuaria Brasileira; v.51, n.4, abr. 2016; 309-319Pesquisa Agropecuária Brasileira; v.51, n.4, abr. 2016; 309-3191678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/21375/13263https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/21375/13503Direitos autorais 2016 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2016-07-04T21:50:30Zoai:ojs.seer.sct.embrapa.br:article/21375Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2016-07-04T21:50:30Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
