THE EFFECT OF TOPOGRAPHICAL MODIFICATION OF HILLSIDE APPLE ORCHARDS ON TREE GROWTH AND PRODUCTIVITY

M. Iancu, I. Neamtu, M. Negoita
The best topographical modification system of hillside lands on two soil types for the apple cultivar 'Starkrimson' grafted on MM. 106 rootstock was studied during 1984–1993. Annual yield was significantly higher (20%) on the brown colluvial soil compared to the slightly eroded soil. Tree rows following contour lines had 57% higher yield than trees on 25 m wide terraces, The cost of forming the contour line treatment was 3 times less than the cost of the treatment with strips and technological traffic lanes and 14 times less than the cost of the terrace treatment. The length of the technological traffic needed to apply phytosanitary treatments in case of the strips with technological traffic lanes treatment represented 23% from the value of the other two tree cropping systems. On lands with up to 12% slope, the contour line tree cropping system is recommended, whereas on steeper lands, the strips with technological traffic lanes treatment had better results.
