Economic efficiency of fruits production of various by growth vigour cultivar and rootstock combinations of apple tree

Abstract

In the orchard of 2006 planting year, a fructification and economic efficiency of apple cultivars Alesya and Vesyalina cultivation on clonal stocks of various growth vigour such as 54-118, 62-396 and PB-4 in the fruiting season on the 6-9 th year after their planting were studied.

It was established that the trunk cross-sectional area, average fruit mass, mass of the fruits removed from a tree depended on the used stock. Those indices at both studied cultivars Alesya and Vesyalina were higher on a semi dwarf root stock 54-118.

In recalculation on an area unit, the highest average yield of the trees of the cultivar Alesya made 44.3 t/hectare, profit and profitability level were higher on a dwarf root stock 62-396 at the planting scheme of 4.0 х 1.5 m. While the highest average yield at the cultivar Vesyalina made 42.5 t/hectare and the profit and profitability were received on a semi dwarf root stock 54-118 at the planting scheme of 4.0 х 2.0 m.
