“…Uma maior precisão experimental foi obtida quando se considerou apenas a área total da parcela. Em contrapartida, Oliveira (2005) destaca que não é recomendada a substituição de bordaduras por um número maior de repetições em experimentos de comparação de híbridos de milho.…”

Experimental accuracy in crop research is directly affected by the size of plots. For this reason, researchers use empirical knowledge to determine plot size. There are also other important aspects for determining ideal plot size. These include the type of crop and the use, or not, of borders. The objective of this research was to verify the necessity of including border material in the value of cultivation and use trials in breeding programs of upland rice and to evaluate the experimental accuracy with and without the inclusion of borders. The research was conducted in an experimental area at the Federal University of Lavras, located in the State of Minas Gerais, during three harvests (2014/2015, 2015/2016, 2016/2017). Thirteen upland rice strains and methods of evaluation (useful area and border) were evaluated. A randomized complete block design with three replications was used to evaluate grain yield. Individual analyses of variance were performed considering the useful areas and the borders for the three agricultural years. A joint analysis was also performed with the use of a subdivided plot involving the location of the harvest in terms of the useful area and border among the rice strains. It was concluded it is necessary to use borders in the value of cultivation and use trials in breeding programs of upland rice as it contributes to the performance and experimental accuracy of research results.

“…The use of border in the experimental units is widespread in field experiments with the aim of reducing the competition among plots (Storck et al 2016). In this point of view, several studies have been carried out to test the efficiency of this technique in different crops (Fernandes and Silva 1994;Costa and Zimmermann 1998;Ribeiro et al 2001;Cargnelutti Filho et al 2003;Oliveira et al 2005). For horticultural crops, however, similar studies were not found.…”

The variability within rows of cultivation may reduce the accuracy of experiments conducted in a complete randomized block design if the rows are considered as blocks, however, little is known about this variability in protected environments. Thus, our aim was to study the variability of the fresh mass in lettuce shoot, growing in protected environment, and to verify the border effect and size of the experimental unit in minimizing the productive variability. Data from two uniformity trials carried out in a greenhouse in autumn and spring growing seasons were used. In the statistical analyses, it was considered the existence of parallel cultivation rows the lateral openings of the greenhouse and of columns perpendicular to these openings. Different scenarios were simulated by excluding rows and columns to generate several borders arrangements and

“…Na cultura do milho, o número adequado de repetições tem sido investigado por Oliveira et al (2005), Velini et al (2006), Catapatti et al (2008) e Cargnelutti Filho et al (2010). De maneira geral, esses trabalhos destacaram a melhoria da precisão por meio de um planejamento experimental adequado.…”
