Abstract:
Apricot-tree as a fruit-tree is defficient in Europe, as well as in the world. It is very good as a product for modification and consumption in the fresh state. Its expanding is limited by the reason of sensibility to low temperatures and very early perishing of fruit-trees. The aim of this experiment was:

To find out a such possibility to fruitful the plantation as soon earlier.
To increase yields per unit square and
To reduce the influence of the prior perishing of fruit-trees.

Object : The experimental plantation is raised 1975, in the Institute of Fruit Production-Skopje; where was investigated the sort Mad*arka on the rootstock apricot-tree.

The soil is aluviale-deluvials, limestone with 16,13 mg/% CaCO₃; 0,66 mg/% P₂O₅ ; 8,9/% K₂O and 8,19 pH of water. The apricot-tree good grow on this soil.

Climate : In the region of Skopje it is moderate-continental with the certain influence of the mediteranean climate. In accord to many-yearth meteorological's data, the average annual temperature of the air is amounting 12,1°C; absolute maximale 40,3°C; and absolute mini-male --22,6°C. The annual sum of temperature is 4 442°C, while the vegetative is 3 906°C. The sum of rain is 528,8 mm from which 292 mm or 55,2% is during the vegetation. The climate is very favourable for growing on apricot-tree.

Forming : The trunk of 70 cm.

Corona : — Palmette with one floor ;

— Free spindle's shrub.

Cutting : — Winters on february to march ;

— Summers's on may to june, when are shortaged green apexs of summer's branches.
