Resumo: Objectives of this work were to determine the sample size (number of plants) to estimate the mean of slender leaf rattlebox (Crotalaria ochroleuca) traits and investigate the relations among traits. In an experimental area of 8 m × 20 m (160 m2), at 147 days after sowing, 110 plants were randomly selected. The following traits were evaluated for each plant: plant height, stem diameter, number of nodes, number of leaves, leaf fresh matter, stem fresh matter, shoot fresh matter, leaf dry matter, stem dry matter and shoot dry matter. Measures of central tendency, variability, skewness and kurtosis were calculated. Normality was verified using the Kolmogorov-Smirnov test and the sample size was calculated to estimate the mean of the traits, assuming estimation errors (semi-amplitudes of the 95% confidence interval) equal to 1%, 2%, …, 30% of the mean. The relations among traits were investigated by scatter plots, correlation and path analysis. To estimate the mean of these ten traits, with a maximum error of 10% of the mean and 95% confidence level, 67 plants are needed. In an experiment, to estimate the mean of each treatment with 10% precision, 67 plants per treatment must be evaluated. The number of leaves has a positive linear relation with leaf fresh and dry matter. Number of leaves and stem diameter have a positive linear relation with stem and shoot fresh and dry matter.

Em área experimental de 8 m × 20 m (160 m2), aos 147 dias após a semeadura, foram selecionadas, aleatoriamente, 110 plantas. Em cada planta foram avaliados os seguintes caracteres: altura de planta, diâmetro de caule, número de nós, número de folhas, matéria fresca de folhas, matéria fresca de caule, matéria fresca de parte aérea, matéria seca de folhas, matéria seca de caule e matéria seca de parte aérea. Foram calculadas as medidas de tendência central, variabilidade, assimetria e curtose. Foi verificada a normalidade por meio do teste de Kolmogorov-Smirnov e calculado o tamanho de amostra para a estimação da média dos caracteres, assumindo erros de estimação (semi-amplitudes do intervalo de confiança de 95%) iguais a 1%, 2%, …, 30% da média. Foi investigada a relação entre os caracteres por meio de diagramas de dispersão, análises de correlação e de trilha. Para a estimação da média desses dez caracteres, com erro máximo de 10% da média e grau de confiança de 95%, são necessárias 67 plantas. Em um experimento, para a estimação da média de cada tratamento com 10% de precisão, devem ser avaliadas 67 plantas por tratamento. O número de folhas tem relação linear positiva com as matérias fresca e seca de folhas. O número de folhas e o diâmetro de caule têm relação linear positiva com as matérias fresca e seca de caule e de parte aérea.Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Cassilândia2022-06-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicosonline.uems.br/index.php/agrineo/article/view/683410.32404/rean.v9i2.6834Revista de Agricultura Neotropical; v. 9 n. 2 (2022): REVISTA DE AGRICULTURA NEOTROPICAL; e6834REVISTA DE AGRICULTURA NEOTROPICAL; Vol. 9 No. 2 (2022): REVISTA DE AGRICULTURA NEOTROPICAL; e68342358-630310.32404/rean.v9i2reponame:Revista de Agricultura Neotropicalinstname:Universidade Estadual de Mato Grosso do Sul (UEMS)instacron:UEMSenghttps://periodicosonline.uems.br/index.php/agrineo/article/view/6834/4961https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCargnelutti Filho, AlbertoSilveira, Daniela LixinskiBubans, Valéria EscaioOsmari, Bruno FillipinSomavilla, Felipe ManfioOrtiz, Vithória MorenaOsmari, Lucas Fillipin2022-08-22T14:16:39Zoai:ojs.pkp.sfu.ca:article/6834Revistahttps://periodicosonline.uems.br/index.php/agrineoPUBhttps://periodicosonline.uems.br/index.php/agrineo/oaiagriculturaneotropical@uems.br || wellingthon.junnyor@uems.br2358-63032358-6303opendoar:2022-08-22T14:16:39Revista de Agricultura Neotropical - Universidade Estadual de Mato Grosso do Sul (UEMS)false
