“…It is highlighted that the production ceiling in both yield locations surpassed the national averages of grain yield close to 1.330 kg ha -1 (CONAB, 2013). The grain yield obtained in Passo Fundo reached the results obtained by Krüger et al (2011) and Bandeira et al (2013), which obtained 1.381 and 1.195 kg ha -1 , respectively. Environmental factors such as temperature, humidity, light and nutrition are related to the growth regulation and to the development of canola plants (Edwards and Hertel, 2011), consequently affecting the production.…”

The canola (Brassica napus L. oil variant) is considered as a winter crop alternative in south Brazil. Thus, the aim of this study was to compare the root growth and the productivity components of hybrid grains of conventional and herbicide tolerant canola in different localities. The experiments were conducted in the municipality of Passo Fundo, Rio Grande do Sul state and Guarapuava, Paraná state, Brazil. The randomized block design with four replication was used. The genotypes evaluated were: Hyola 61 and H92002 (conventional), Hyola 571 CL and K10050 (imidazolinone-resistant), and Hyola 751 TT (triazine-resistant). In order to evaluate the root system, soil monolith were collected and image analysis measuring the superficial area and the total root volume of the sample in diameter classes, root density and specific surface area were done. The grains productivity components and the number of branches in the plant were measured through the number of siliques in the branches. The productivity of the grains and the thousand grain mass were measured as well. The canola hybrid presented higher root length, surface area and volume in the diameter scale between 1 and 5 mm of density. In addition, there were variations in the growth of roots and grain productivity in different environments, in which imidazolinone-tolerant hybrids presented higher development of the roots, as well as, higher grain productivity in the different environment studied.

“…Nesse cenário, em experimentos com a cultura de canola, além da produtividade de grãos e do teor de óleo, o dimensionamento da quantidade de massa verde e/ou de massa seca de parte aérea é importante para avaliar o potencial da espécie como cobertura de solo. Na cultura de canola, aspectos relacionados à produtividade de grãos e/ou teor de óleo têm sido avaliados em pesquisas desenvolvidas por Bandeira et al (2013), Kaefer et al (2014), Krüger et al (2011), Luz et al (2013) e Sanches et al (2014). Além desses dois caracteres, a massa seca e/ou massa verde de parte aérea de canola tem sido dimensionada em pesquisas de Bandeira et al (2013), Castro & Boaretto (2004), Kaefer et al (2014), Pavinato et al (1994) e Sanches et al (2014).…”

ResumoOs objetivos deste trabalho foram determinar o tamanho ótimo de parcela e o número de repetições, para avaliar a massa verde de canola (Brassica napus L.). Foram realizados 27 ensaios de uniformidade de 5m×5m (25m 2 ), sendo nove ensaios para cada um dos seguintes híbridos: Hyola 61, Hyola 76 e Hyola 433. Cada ensaio foi dividido em 25 unidades experimentais básicas (UEB) de 1m×1m, totalizando 675 UEB. Foi pesada a massa verde das plantas de cada UEB. O tamanho ótimo de parcela (Xo) foi determinado por meio do método da curvatura máxima do modelo do coeficiente de variação, e as comparações de médias, entre os híbridos, foram feitas pelo teste de Scott-Knott. O número de repetições, para experimentos nos delineamentos inteiramente casualizados e blocos ao acaso, em cenários formados pelas combinações de i tratamentos (i=3, 4, ..., 50) e d diferenças mínimas entre médias de tratamentos a serem detectadas como significativas a 5% de probabilidade, pelo teste de Tukey, expressas em percentagem da média do experimento (d=10%, 13%, ..., 40%), foi determinado por processo iterativo até a convergência. O tamanho ótimo de parcela para avaliar a massa verde de canola é 6,41m 2 . Quatro repetições, para avaliar até 50 tratamentos, nos delineamentos inteiramente casualizados e blocos ao acaso, são suficientes para identificar, como significativas a 5% de probabilidade, pelo teste de Tukey, diferenças entre médias de tratamentos de 41,4% da média do experimento.Palavras-chave: Brassica napus L., experimentação agrícola, planejamento experimental, precisão experimental. Plot size and number of repetitions in canola AbstractThe objectives of this work were to determine the optimum plot size and number of repetitions, to evaluate the fresh weight of canola (Brassica napus L.). Twenty-seven uniformity trials of 5m×5m (25m 2 ) were conducted. Each trials was divided in 25 basic experimental units (BEU) of 1m×1m, totaling 675BEU. The fresh weight of plants, in each BEU was weighed. The optimum plot size (Xo) was determined by the method of maximum curvature of the model coefficient of variation and the means compared, among hybrids, by Scott-Knott test. The number of repetitions, for experiments on completely randomized and randomized block designs, in scenarios of combinations of i treatments (i=3, 4, ..., 50) and d minimal differences between treatments means, to be detected as significant, 5% probability by Tukey test, expressed in percentage of the average of the experiment (d=10%, 12%, ..., 40%), was determined by iterative process until convergence. The optimum plot size to evaluate the fresh weight of canola is 6.41 m 2 . Four replications, to evaluate up to 50 treatments, in completely randomized and randomized block designs, are sufficient to identify, as significant at the 5% probability by Tukey test, differences between treatment means 41.4% of the average experiment.

“…Information on spacing arrangements between lines that can promote both yield and canola seeds' quality in the northwest region of Paraná state is scarce. Farmers have adopted other species' cultivation practices (Krüger et al, 2011;Jacob Junior et al, 2012;Bandeira et al, 2013).…”
