Resumo: The objective of this work was to establish plant arrangement effect on the optimal plot size estimates of grain sorghum yield experiments. The experimental design was a completely randomized block with factorial combination of two row spacings (0.50 m and 0.80 m), and three plant densities (100 thousand, 160 thousand and 220 thousand plants ha-1), and four replications. The area of each replication was composed by 12 basic units measuring 0.50 m in row length. Models were adjusted in optimum plot size estimates that correlate variance or variation coefficient with four simulated plot sizes. Plot size was 3.2 m2 for grain sorghum yield experiments. Increasing number of plants in row did not result in higher seed yields, however it improved sorghum quality experiment. Estimation of the ideal plot size depends on number of plants used in the basic unit. Row spacing did not affect estimation of the ideal plot size.

O delineamento estatístico utilizado foi o de blocos ao acaso, num esquema fatorial com dois espaçamentos entre linhas (0,50 m e 0,80 m), três densidades de semeadura (100 mil, 160 mil e 220 mil plantas ha-1) e quatro repetições. Cada repetição foi composta, na área útil, por 12 unidades básicas de 0,50 m da linha de cultivo. Foram ajustados modelos, na estimativa do tamanho ótimo de parcela, que relacionam a variância ou o coeficiente de variação com quatro tamanhos simulados das parcelas. O tamanho estimado de parcelas, na cultura de sorgo granífero, é de 3,2 m² para a variável produtividade de grãos. O aumento do número de plantas, na linha, não proporciona incrementos na produtividade de grãos, porém resulta em melhorias da qualidade de experimentos com sorgo. A estimativa do tamanho ótimo de parcela depende do número de plantas utilizadas na unidade básica. O espaçamento entre linhas não influencia na estimativa do tamanho ótimo de parcela.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLopes, Sidinei JoséStorck, LindolfoLúcio, Alessandro Dal'ColLorentz, Leandro HomrichLovato, CláudioDias, Vilnei de Oliveira2005-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6989Pesquisa Agropecuaria Brasileira; v.40, n.6, jun. 2005; 525-530Pesquisa Agropecuária Brasileira; v.40, n.6, jun. 2005; 525-5301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6989/4037info:eu-repo/semantics/openAccess2014-09-22T17:26:50Zoai:ojs.seer.sct.embrapa.br:article/6989Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-22T17:26:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
