Urea har vore lite brukt til gjødsling i jordbruket i Norge. Prisforskjellen mellom urea og andre nitrogengjødselslag har vore liten. Oftast har ein også bruk for tilførsel av meir enn nitrogen, og da har NPK-gjødsel eller andre samansette gjødselslag vore meir aktuelle enn rein N-gjødsel. Med den store prisoppgangen på gjødsel generelt i 2008-2009 har prisforholdet mellom ulik gjødsel endra seg, og ei tid var urea mykje billegare enn anna N-gjødsel. Urea blir mykje brukt globalt. Som eit lite foredla produkt, er prisnivået internasjonalt relativt lågt, og urea kan derfor bli meir aktuelt også hos oss framover.

Norway has long traditions in growing oat for feed and food. A good raw material quality is an important field giving different quality parameters an increased focus. Important quality characteristics, both for feed and food, are linked to polysaccharides, particulary beta-glucan and starch. It is of great importance to enhance and optimise the polysaccharide composition according to different end-uses. New varieties are therefore developed worldwide focusing on enhanced nutritional properties. However, it is possible to improve or secure a stable quality of existing commercial oat varities by focusing on different growing conditions. In this project Norwegian commercial oat varieties were exposed to controlled climate chambers, field trials in plastic tunnels and ordinary field trials. This will give a better understanding and provide new knowledge to secure a stable raw material quality and a better utilization of Norwegian oat to different end uses. In addition, it provides an improved understanding of the relationships between climate factors experienced in a Nordic climate and the quality of fibre and starch.

Bipolaris sorokinana (teleomorph Cochliobolus sativus) is a widespread pathogen of cereals and many grasses. It can infect seeds, roots and leaves, causing seedling blight, common root rot, foot rot and spot blotch. Inoculum of B. sorokiniana may be seed-borne or arise from infected plant debris in the field and from conidia in the soil. Recent years the pathogen has occurred at high frequencies in seed lots of barley in Norway, especially in the cvs Edel and Annabell. A large proportion of the seed lots tested since 2004 were infected and the average infection frequencies were rather high. In order to evaluate the importance of the seed-borne inoculum in barley and to test the effect of seed treatment fungicides against the pathogen, field, greenhouse and laboratory experiments have been carried out with heavily infected barley seed. The infection level was reduced and plant weight, plant height, field emergence and yields were significantly increased by chemical treatment. The best effect was seen with an imazalil+flutriafol compound which increased the yield by approximately 35 % compared to untreated. A healthy untreated seed lot of the same cultivar included in one of the experiments showed approximately the same level of emergence and yield as the best fungicide treatment of a heavily infected seed lot. The investigations demonstrate that the use of healthy seed, or seed treated with an effective fungicide, is important to reduce the yield losses from B. sorokiniana.

Timoteibaserte frøblandingar dominerer i Norge. Timotei har god overvintringsevne, rask etablering, enkel frøavl og god fôrkvalitetet, men toler intensiv drift og beiting dårleg. Raigras- og raisvingelbasert eng er alternativ langs kysten av Sør-Norge. I innlandet er bladfaks og hundegras aktuelle.
