Development of the abaveground part of apple tree plantation founded with „Knip Baum” type

Abstract

The orchard was established in spring, 2004 with crowned apple trees of “KNIP BAUM” type. The distance of plantation is 3,25 x 1,25 m, the rootstock is M 9 and the studied varieties are Idared, Golden Delicious Reinders, Jonagold Decosta and Čampion. It was established that the development of the apple trees into plantation depends greatly on the type of the planting material used at the foundation of the orchard. On the bioconstructive parameters of the apple tree plantation and the length of the trunk circumference influence the biological features of the variety and agrotechnic level used in the orchard. At the end of the fourth year after plantation, the apple trees have reached optimal bioconstructive parameters for such association variety/rootstock. The height of the trees under the study constituted 328-347 cm, and the length of the crowns was 170-177 cm. These parameters of the crown directly contribute to the optimal capitalization of the productive volume of the crown and the space of nutrition means to plantation.
