Variety’s influence on crown structure and apple tree plantation productivity 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 also established that in the second year after plantation these varieties have formed a tree skeleton totalized length of 32,3-51,3 m/tree. The quantity of bud-fruit formations for one tree is 125-228 pieces, for a linear meter of two-year old branches is 16,3-26,1 pieces, for the three-old branches is 9,5-25,5 pieces, and for four-old branches is 2,8-18,7 pieces. This quantity of bud-fruit formation and annual branches will permit to obtain a yield of 35-40 t/ha in the forth-year after plantation. The accumulated fruit production during the researches of the studied varieties was 32,28-39,54 t/ha. The whole production had a fruit diameter of more than 70 mm.
