Optimal plot size in wheat with comparison of three methods
ABSTRACT The objectives of this study were to determine the optimal plot size (Xo) to evaluate the fresh matter productivity of wheat (Triticum aestivum L.) and check whether Xo differs between three determination methods. Five uniformity trials were carried out. Trials 1 and 2 were carried out, res...

| description | ABSTRACT The objectives of this study were to determine the optimal plot size (Xo) to evaluate the fresh matter productivity of wheat (Triticum aestivum L.) and check whether Xo differs between three determination methods. Five uniformity trials were carried out. Trials 1 and 2 were carried out, respectively, with the cultivars TBIO Sossego and TBIO Toruk, both sown on August 3, 2018. Trials 3, 4 and 5 were carried out with the cultivar TBIO Audaz, sown, respectively, on June 7, 2019, June 27, 2019 and July 18, 2019. Fresh matter productivity was evaluated in 540 basic experimental units (BEU) of 1 m × 1 m (108 BEU per trial). The BEU was formed by five rows of 1.0 m in length, spaced 0.20 m apart, totaling 1.0 m2. The optimal plot size was determined using the methods of modified maximum curvature, linear response and plateau model and quadratic response and plateau model. The optimal plot size differs between the methods and decreases in the following order: quadratic response and plateau model (15.78 m2), linear response and plateau model (7.11 m2) and modified maximum curvature (2.56 m2). The optimal plot size to evaluate the fresh matter productivity of wheat is 7.11 m2 and the experimental precision stabilizes from this size on. |
