Raspberry Production in High Tunnels


To produce primocane raspberries in high tunnels and transfer this knowledge to growers in northeast Minnesota.

We utilized one of the high tunnels at NCROC for this primocane high tunnel raspberry project to compare the five raspberry cultivars selected for this experiment. The five cultivars turned out quite different from berry earliness and quality to cultural characteristics. Farmers can pick their favorite ones based on our recommendations. We used predator mites to control spider mites and fertigation for fertility management. Our community partner- Doug Houffbauer's raspberry tunnel was pretty good in 2008. He had some problems with his raspberry tunnel due to irrigation issue (not enough water and the tomato tunnel has priority) and the extremely cool summer in 2009. The plants were small and yield was low in 2009.


In the first/planting year, 154 lb of berries were harvested from our 21x 48 ft high tunnel at NCROC in 2008 which was equivalent to 6600 lb/acre;
In the second year after planting, over 350 lb of berries were harvested from our 21 x 48 high tunnel at NCROC in 2009 which was equivalent to 15,000 lb/acre.
Pest and disease are under control in both years.
There was some minor winter damage to some cultivars. But in general, they all survived the winter well.
We will make recommendations for the five cultivars tested in the future technical report.
