Abstract
This scientific article presents experimental data devoted to studying the effect of tree density on productivity of Lola peach trees in an orchard, when grown on the dwarf vegetatively propagated rootstock VVA-1.
The study found that the productivity of an individual tree decreases proportionally from 43.8 to 22.0 kilograms when planted in a sparse (6.0 x 4.0 m) to a dense (6.0 x 1.5 m) planting. However, overall productivity per unit of orchard area increases from
182.2 to 258.8 centners/ha, or by 41.8%.
The specific productivity of the Lola peach variety grown on the VVA-1 rootstock, taking into account the tree placement pattern in the orchard, as well as the development of crown projection and volume, tends to increase with the 6.0 x 2.0 meter planting pattern. With this planting pattern, the productivity index per 1 m³ of volume and 1 m² of crown projection reaчes its maximum value of 4 kg/tree, with a total yield of 258.8 c/ha.
