Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Fruit yield in wild berry species can vary greatly from year to year. Despite the short growing season and low temperatures in the Arctic region, many small fruit species are thriving under such conditions. Cloudberry (Rubus chamaemorus L.) is a perennial dioecious plant dependent upon insects for pollination. Cloudberries are high-valued, but fruit set and yield can fluctuate substantially between years. Although most commercial harvesting of cloudberries is done from wild stands, a few commercial cultivars are available, and cultivation techniques for natural stands have been developed. There is limited knowledge of variations in cloudberry crops. Increased research on this topic can be crucial for enhancing our knowledge of cloudberry cultivation and having better predictions for increased commercial utilization.

Only approximately 2% of the land area in Northern Norway is suitable for agricultural purposes. The short growing season and cold climate impose limitations for what can be produced. Agriculture still takes place here, with forage crops for livestock being the most important. On free rangeland areas, including both semi-natural and natural habitats, livestock grazing is common. The biomass production on some of these rangelands is presumed to be high, although little is known about the actual fodder potential. In 2022 a preliminary study was performed to determine abundance and variety of wild pasture plants, dry matter yield (DM) and feed quality in the (presumed) highest yielding vegetation types. Results showed an average of 1520 kg DM ha–1 in spring and 5380 kg DM ha–1 in autumn. Early season feed quality was high, but with rapidly decreasing trends. The number of pasture plants was also high. Our results show that in sub-arctic Northern Norway grazing animals can harvest substantial amounts of ‘free’ fodder of good quality, yet the official statistics show that only 14% of this resource is utilised. Continuous grazing is needed to maintain production and fodder quality in these areas.
