The study was conducted in the period 2006 – 2008 at Experimental Station of Agriculture – Han Krum. Cultivars were are tested Bing, Germersdorfer, Van and Biggareau Burlat in the following inside row distances of planting V1 – 3 m, V2 – 4 m, V3 – 5 m and intercrops distances 6 m. The following indices was analyzed cross section of the stem – cm² (at the end of the period), yield of the tree (kg), mean fruit mass (g), coefficient of productivity (kg/cm²), theoretical yield (kg/ha). Were analyzed and chemical indicators sugars (%), acids (%), dry matter (%) and ratio sugars/acids. The Crosssection of the stem and yield from a tree increase with increasing the distance of planting for variants of cultivars Van, Bing, Biggareau Burlat and Germersdorfer. The coefficient of the productivity is of the highest values for V1 with relatively low to V3 of the tested cultivars. With the decrease intra row distance the three variants is increased the theoretical yield. Different planting distances no impact on chemical composition of the fruits.
