Resumo: | The importance of the cultivation of oilseed flax has increased in the Brazilian agricultural scenario, and therefore, research must be carried out to have better recommendations for cultivation and experimental precision. For research to be reliable, there is a need for adequate experimental planning. In this context, the objective of this work is to propose an experimental plan, with estimates of plot size, sample size, and the number of replicates, to increase the precision and reliability of experiments carried out with the oilseed flax crop. The experiments were carried out in three environments and two agricultural years, in a randomized block design with four replicates and two varieties of oilseed flax (golden and brown). In both years, plants were sampled in the plot and measured for: total height, technical length, productive length, main branch diameter, number of capsules per plant, number of seeds per capsule, and grain mass per plant. From these data, the plot size was estimated using the Pimentel-Gomes method, and it was verified that 30 plants, arranged in 6 rows of cultivation, are needed to compose the usable area of the plot, with 2 border rows, totaling 90 plants per plot. Differently, with the grain yield data, in which the effects of the parameters of the mathematical model of each experimental trial were removed, the plot size was estimated through the Paranaíba method, and it was identified that the plots must be 9.86 m². For sampling, an optimal size of 5.4 m² was observed, considering a semi-amplitude of the confidence interval (D%) equal to 20% of the mean. Also, the need to use five replicates per plot was verified, considering a least significant difference in the Tukey test expressed as a percentage of the mean of 25%. |

Para que as pesquisas sejam confiáveis, há a necessidade de um planejamento experimental adequado. Neste sentido, o objetivo deste trabalho é propor um plano experimental, com estimativas de tamanho de parcela, tamanho de amostra e número de repetições, a fim de aumentar a precisão e confiabilidade de experimentos realizados com a cultura do linho oleaginoso. Os experimentos foram conduzidos em três ambientes e dois anos agrícolas, em delineamento em blocos casualizados com quatro repetições e duas variedades de linho oleaginoso (dourada e marrom). Em ambos os anos, as plantas foram amostradas na parcela e mensurado a altura total, comprimento técnico, comprimento produtivo, diâmetro do ramo principal, número de cápsulas por planta, número de sementes por cápsula e massa de grãos por planta. A partir desses dados, estimou-se o tamanho da parcela pelo método Pimentel- Gomes, e verificou-se que são necessárias 30 plantas, dispostas em 6 linhas de cultivo, para compor a área útil da parcela, com 2 linhas de bordadura, totalizando 90 plantas por parcela. Diferentemente, com os dados de produtividade de grãos, em que foram retirados os efeitos dos parâmetros do modelo matemático de cada ensaio experimental, o tamanho da parcela foi estimado pelo método Paranaíba, e identificou-se que as parcelas devem ter 9,86 m². Para amostragem, observou-se um tamanho ótimo de 5,4 m², considerando uma semi-amplitude do intervalo de confiança (D%) igual a 20% da média. Também foi verificada a necessidade de utilização de cinco repetições por parcela, considerando diferença menos significativa no teste de Tukey expresso em percentual da média de 25%.Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em AgronomiaCentro de Ciências RuraisLúcio, Alessandro Dal’Colhttp://lattes.cnpq.br/0972869223145503Follmann, Diego NicolauNardino, MaiconLambrecht, Darlei Michalski2023-08-01T12:54:48Z2023-08-01T12:54:48Z2023-07-20info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/29816porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2023-08-01T12:54:48Zoai:repositorio.ufsm.br:1/29816Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2023-08-01T12:54:48Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
