Sažetak
Investigations into the effect of crop load on yield and fruit quality of young apple ‘Golden Delicious’, grafted on M9 rootstock was conducted in years 1998-1999. The orchard was planted in the spring 1997, at a spacing of 3.0 x 0.8 m (4166 trees/ha) and trained to super spindle. On the basis of the rate of natural fruit drop in the second growing year, three experimental groups were established, classified as trees of low (A), medium (B) and high initial productivity (C). In that year crop load was regulated by hand thinning in group A to 5, in group B to 15 and in group C to 25 fruits/tree. In the third growing year crop load was regulated to three levels (low, medium and high) equally in all groups (40, 60 and 80 fruits/tree). The results showed significant effect of crop load on yield and fruit quality. The best results were obtained in all groups when crop load was medium. This result illustrates the importance of regulating fruit load in the intensive apple orchards, particularly during tree establishment.
