Abstract
). Each trial was divided into 36 basic experimental units (BEU) of 1 m × 1 m, totaling 1,728 BEU. In each BEU, the fresh matter was weighed. The optimum plot size was determined by the method of maximum curvature of the coefficient of variation model. The means were compared among sowing densities by the Scott-Knott’s test. The number of repetitions — for experiments with completely randomized and randomized block designs, in scenarios of i treatments
Highlights
The vetch (Vicia sativa L.) is an annual winter legume used as forage for animal feed and as cover crop (Santos et al 2012)
Based on the method of maximum curvature of the coefficient of variation model developed by Paranaíba et al (2009), the optimum plot size
The uniformity trials were carried out with vetch (Vicia sativa L.), common cultivar, in the experimental area located at lat 29°42′S, long 53°49′W and 95 m of altitude
Summary
The vetch (Vicia sativa L.) is an annual winter legume used as forage for animal feed and as cover crop (Santos et al 2012). Researches with vetch, grown isolated or in mixture with other cover crops (Lithourgidis et al 2006; Tuna and Orak 2007; Seidel et al 2011; Ansar et al 2013; Cherubin et al 2014; Basbag et al 2015; Desalegn and Hassen 2015), have demonstrated promising aspects of this crop. In pure and mixed cultivation with oat, wheat, vetch and barley, Ansar et al (2013) used plots of 15 m2 and evaluated the fresh matter weight in 1 m2 of each plot
