Resumo: | Proper planning of experiments in the culture of castor bean is one of the ways to maximize the research information. The aim of this study was to determine the optimum plot size and number of replications and the influence of spacing between plants in experiments involving castor bean crops. The experiment with the hybrid Sara was conducted at the Federal University of Santa Maria in 2010 with a spacing of 1.2 m between rows and between plants of 0.4, 0.6 and 0.8 m. Each plant was evaluated taking into account: the number of racemes, fruit weight, the average length of the racemes, and fruit number, with the plant identification by the order number of the row and the number of plants within the row. The optimum plot size is eight plants for all spacings and all variables. However, the area of optimum plot size inside the spacing depends on the area occupied by the basic unit. Thus, the plot area is 3.84, 5.76 and 7.68 m2 for each spacing of 0.4, 0.6 and 0.8 m, respectively. Twelve replications in randomized block design, are sufficient to identify, as significant at 5% probability, differences between treatment means of 27%. |

Os objetivos deste trabalho foram determinar o tamanho de parcela e o número de repetições para a cultura de mamoneira e verificar a influência do espaçamento entre plantas no plano experimental. O experimento com o híbrido Sara foi conduzido na Universidade Federal de Santa Maria, em 2010, com espaçamento entre linhas de 1,2 m e espaçamentos entre plantas de 0,4, 0,6 e 0,8 m. Foram avaliados em cada planta o número de rácemos, peso de frutos, comprimento médio dos rácemos e número total de frutos, com identificação da planta pelo número de ordem da fileira e o número da planta dentro da fileira. O tamanho ótimo de parcela é de oito plantas para todos os espaçamentos e para todas as variáveis. Porém, a área do tamanho ótimo de parcela em cada espaçamento depende da área ocupada pela unidade básica. Assim, a área da parcela é de 3,84, 5,76 e 7,68 m2 para os espaçamentos entre plantas de 0,4, 0,6 e 0,8 m, respectivamente. Doze repetições, no delineamento blocos ao acaso, foram suficientes para identificar diferenças entre médias de tratamentos de 27%, com 5% de probabilidade de erro.Universidade Federal Rural do Semi-Árido2015-11-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/391010.1590/1983-21252015v28n428rcREVISTA CAATINGA; Vol. 28 No. 4 (2015); 253-258Revista Caatinga; v. 28 n. 4 (2015); 253-2581983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAporhttps://periodicos.ufersa.edu.br/caatinga/article/view/3910/pdf_327Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessPaludo, André LuizLopes, Sidinei JoséBrum, BetaniaStorck, LindolfoSantos, Daniel dosHaesbaert, Fernando2023-07-03T17:12:47Zoai:ojs.periodicos.ufersa.edu.br:article/3910Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:11.183380Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
