Productivity in the orchard can be improved by maximizing preharvest factors, including training systems based on compact two-dimensional canopies, high-density trees, and the availability of efficient size-controlling rootstocks. Improved densities have been combined with planar canopies, providing better mechanical and manual pruning and flower thinning, which enhanced yields while optimizing fruit quality and production costs. The study aimed to assess the productive potential of several peach and nectarine cultivars, determining the quantity of produced fruits correlated to flowers. In 2019-2024, two different training systems, Trident (4.0 x 2.0 m - 1,250 trees/ha - 3,750 axis/ha) and Vertical Axis (4.0 x 1.5 m - 1,666 trees/ha - 1,666 axis/ha), have been tested on 14 peach and 16 nectarine cultivars for temperate climate. Three different rootstocks, GF677, Adesoto, and Mirobolan29C, were used for some cultivars.
