| 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. | |
