Description
In this work, the "yield potential" is proposed as a new methodology to relate production with quality, which allows us to achieve the optimal bearing status of the tree for each orchard and season. The "yield potential" is defined as the maximum production that can be obtained in each orchard ecosystem as a function of a commercial and qualitative target such as fruit size or sugar content. The presented methodology is based on the differentiation of the bearing status of the trees by hand thinning, and grouping them, after harvest, according to the number of fruits per tree for nonlinear regression analysis. Estimating thinning needs or effectiveness to obtain the desired commercial fruit size and relating average fruit weight per tree with commercial fruit size are the most important achievements of this methodology.
