DEVELOPMENT OF ROOT SYSTEM OF APPLE-TREES ACCORDING TO THE TYPE OF CROWN FORMING
06.00.00 Agricultural sciences
DescriptionWe studied the architecture of the root system of apple tree varieties (Idared, Golden Delicious, Rei-nette Simirenko, Florina grafted on the rootstock M9), planted in 2003, according to the scheme 4 x 1 and formed by type: Russian spindle (k) Knip Baum, Bee Baum, Sollux. We found out that on mid loamy soil with drip irri-gation, the bulk of the roots located at a depth of 10 - 60 cm regardless of the type of crown formation. Large (more than 3 mm) roots of Reinette Simirenko and Florin varieties of trees in age of seven have penetrated to a depth of 60 - 80 cm while forming Russian spindle and Knip Baum crown-type and their length and their weight was 5 – 8% of the overall performance

COMPARATIVE EFFECTIVENESS OF DIF-FERENT TYPES OF FORMATION OF APPLE TREE ORCHARDS IN THE SEAL
06.00.00 Agricultural sciences
DescriptionThe article presents the results obtained in experi-ments at the effect of the formation of crown of apple varieties, such as Idared, Golden Delicious, Florina and Reinette Simirenko on economic affect in Kuban region fruit zone. The estimation of different types of forming crowns is given. The best results were obtained in forming crowns in type of Bee Baum and Sollux for all varieties
