Dutch blueberry growers direct themselves mainly to the fresh market. Therefore, spreading of the harvest period and fruit quality (size and taste) are very important. Hence a proper cultivar choice is of prime importance.

In 1983 an experiment with 15 cultivars was started and up till now the following cultivars can be recommended : very early ripening (mid July) : Bluetta early ripening (2nd half of July) : Patriot and Bluejay mid season (end of July/beginning of August) : Bluecrop and Berkely late ripening (mid August) : Dixi very late ripening (2nd half of August) : Elliot For machine harvesting and processing the cultivars Ama, G71 and 13/16 A appear very suitable (very productive but with small fruits).

Recently trials on trickle irrigation and fertigation have been started. Trials on advancing and delaying the harvest period and on pruning methods are being planned.
