Abstract
Investigations on the effect of irrigation with Polyfeed fertilizer were compared with broadcast Polyfeed fertilization without irrigation on the tree performance of Golden Delicious and Pinova apples grafted on M9 rootstock.
Two orchard experiments were conducted, one with Golden Delicious in the 2nd and 3rd year after planting, and the other with Pinova in the 2nd season.
Orchard spacing was 3.2 x 0.7 m and trained to a slender spindle.
The results showed no significant effect of applied irrigation treatments on tree vegetative performance and internal fruit quality attributes (firmness, soluble solid concentration and starch index) on both cultivars.
However, irrigation did improve fruit size and yield per tree.
Results indicated positive effects of irrigation on tree performance in high density apple orchards during tree establishment.
