Abstract

The vegetative and reproductive growth, of Anna apple trees grafted on MM 106 and under two training, systems, cordon and vase shape, were put ur.der study. Cordon system were divided into Oblique at (1.25X0.60 m), and Cordon at three tree spacing (1.25X2.0;3.0X3.0 and 4.0X4.0 m). Vase shape was at the same later three spacing. Oblique cordon, the high plant density, is a new technique of pl‌anting, yielded highest production (25.2 to 32.5 ton per feddan.) Cordon with 3.0X3.0 m tree spacing, which gave the largest tree, its yield per tree (around 18.7kg) with production feddan (around 8.8 ton). Vase shape with 2.0X1.25 m tree spacing, gave moderate yield tree (12.5 to 14.9Kg), whileit gave a high yield per feddan (21.0 to2S.0 ton). On the other hand, Vase shape with 4.0 X 4.0 m spacings tree, in‌duced good vegetative growth but lowest yield per feddan (4.3 to 5.7 ton). Vase shape under any spacing gave fruits with slightly better quality better quality than those obtained by Cardon systems.
