Abstract: A B S T R A C TThe objective of this study was to determine the optimum plot size (Xo) and number of replicates to evaluate millet shoot fresh matter in times of sowing and cuts. Uniformity trials of 6 × 4 m (24 m 2 ) were carried out in three sowing times, in the agricultural year of 2013-2014. Each uniformity trial was divided into 24 basic experimental units (BEU) of 1 × 1 m (1 m 2 ) and the shoot fresh matter of plants in each BEU was weighed. The Xo was determined by the method of maximum curvature of the… Show more

“…The replicates number to determine the ryegrass fresh matter weight in a small number of treatments was lower in the completely randomized design in relation to the randomized block design (Tables 2 and 3). This behavior is expected due to the efficiency of the completely randomized design on homogeneous areas and has been described in other experimental planning studies (CaRGNELuTTI FILHo et al, 2014, 2015BuRIN et al, 2016;LaVEZo et al, 2017;CHaVES et al, 2018). For a high treatments number, the number of replications tends to equalize between the two experimental designs.…”

“…So, it is verified that to obtain a high precision (d = 10%) the number of replications is too high, making experimental conduction unfeasible. For cases of i = 50 treatments and d = 10% in completely randomized design and randomized block design experiments, it was verified the need to use 27.41 to 62.98 replications (CaRGNELuTTI FILHo et al, 2014, 2015BuRIN et al, 2016;LaVEZo et al, 2017;CHaVES et al, 2018), indicating the infeasibility of experimental conduction at this precision level.…”

“…This wide variability scenario of ρ, s 2 , m, CV, Xo and CV Xo statistics among 48 uniformity trials is important for the properly dimensioning of plot size and number of repetitions. In field areas, this wide variability has also been observed in other cover crops, such as: black oat (Cargnelutti Filho et al 2014a), jack bean (Cargnelutti Filho et al 2014b), forage pea (Cargnelutti Filho et al 2015a), canola (Cargnelutti Filho et al 2015b), millet (Burin et al 2015;Burin et al 2016) and pigeonpea (Santos et al 2016).…”
