Correct experimental planning is important to obtain more reliable data with high experimental precision. In this way, the results obtained and the technical recommendations generated are more reliable and representative. Thus, the objective of this work is to estimate the plot and sample sizes and the number of repetitions for the variables (a) number of pods per plant and (b) mass of pods per plant for pea (Pisum sativum L.) cultivation. Uniformity tests were carried in the years 2016, 2017, and 2018 in the experimental area of the Crop Science Department at Federal University of Santa Maria. The cultivar used was Pea Grain 40, which has an indeterminate growth habit, with a cycle of 75–90 d and a cylindrical pod. The plot size for evaluating the number of pods per plant and the mass of pods per plant for pea cultivation is eight and nine plants, respectively. The sample size for evaluating the number of pods per plant and the mass of pods per plant is eight plants in the direction of the line with a half-width of the 20% confidence interval of the mean. For the variables number of pods per plant and pod mass per pea plant, 10 and 12 repetitions are required, respectively, to evaluate up to 20 treatments in a randomized block design and in the incomplete blocks design with up to 100 treatments for significant differences of 35% between treatment averages.

豌豆测试实验计划

正确的实验计划对于以更高的实验精度获取更可靠的数据很重要。这样，获得的结果和产生的技术建议更加可靠和具有代表性。因此，这项工作的目的是为变量（a）豌豆（Pisum sativum）的变量（a）每株豆荚的数量和（b）每株豆荚的质量估计样地和样本大小以及重复次数。L.）栽培。分别在2016年，2017年和2018年在圣玛丽亚联邦大学作物科学系的实验区进行了均匀性测试。所使用的品种是豌豆籽粒40，它具有不确定的生长习性，周期为75-90 d，并有一个圆柱形的荚果。用于评估每株豌豆的荚果数量和每株豌豆种植的荚果质量的样地大小分别为8株和9株。用于评估每株豆荚数量和每株豆荚质量的样本大小为在线方向上的八株植物，均值的20％置信区间的一半为宽度。对于每个植物的豆荚数和每个豌豆植物的豆荚质量的变量，分别需要重复10和12次，
