DENSE PLANTATIONS OF APRICOT-TREE

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.
