Målsetningen med friske norske delikatessebær er å utnytte markedspotensiale for friske bær. Det finnes et marked for friske bær, men det krever profesjonell satsing og god organisering i alle ledd. Høy kvalitet er avgjørende for å lykkes.

Kornarealet i Nord-Norge er sterkt redusert etter 1945. Denne utviklinga ser nå ut til å snu, da flere og flere brukere i nord fatter interesse for å dyrke bygg for krossensilering. Tidlig såing og maskinsamarbeid er avgjørende for resultatet av denne dyrkings-metoden. Bruker i Troms med produksjon av geitmelk har oppnådd bedre dyrehelse og spart kraftfôr ved bruk av krossensilert bygg.

Agriculture in Latvia has been going through major reforms since 1991. State farm ownership exists only in a negligible quantity only for research and training purposes and most of the land has been returned to its previous owners, or their descendants, from the times before collectivization. During the Soviet period a number of collective farms were established. Most of these still exist, but the legal form has been changed and they operate on private owned land. Also new ones have been formed. As a result of the agricultural reforms, the accounting, tax and statistical systems that had been established in the old structure were no longer applicable. An urgent need thus arose for the development of new systems for the large number of new family farms. NILF became involved in this work on initiative of the Agricultural University of Norway (NLH), which at that point was cooperating with the Latvian Agricultural University, and was already planning several projects in Latvia in 1993. In cooperation with the Latvian State Institute of Agrarian Economics (LVAEI), NILF was to assist in the development of systems for collecting and making use of financial data for individual farm management and the development of Latvian agricultural policy. The project received financial support from the Ministry of Foreign Affairs' Program for Cooperation with Central and Eastern Europe, and got under way in the summer of 1996. A project unit was established within LVAEI, which was responsible for all work regarding farm statistics. This included the establishment of farm statistics, adaptation to the European Union's Farm Accountancy Data Network (FADN), as well as systems for farm planning. The adaptation to FADN received some support and training assistance from a Danish project. NILF's project constituted the major part of the LVAEI project unit, both with regard to work load and funding. From the Norwegian point of view, the cooperation with the Latvian project unit functioned extremely well, and the unit has continued following the completion of the project. [...]

A new white clover cultivar, Norstar, with excellent winter hardiness and good yield potential has been released (1999) for northern and upland parts of Norway. In a field experiment in Tromsø (690 39"N), the dry matter (DM) yield and persistence of Norstar in mixtures with different grass species was studied. The plots were subjected to simulated grazing or cut for silage, and fertilised with a yearly total of 60kg Nha-1. DM yields of the clover and grass components were determined during three growing seasons. The different grass mixtures had no direct impact on DM yield of clover, but in the first year the clover proportion of the total grass/clover yield was lower in mixture with timothy/meadow fescue than in mixture with smooth meadowgrass. However, in the following years the clover proportion of this mixture increased, whereas it declined in the mixture containing smooth meadowgrass. In 1999, the clover content in both mixtures was about 30%. Cutting regime had no influence on clover yield in either of the mixtures. Simulated grazing depressed the grass yield in white clover/timothy/meadow fescue mixtures, but not in white clover/smooth meadowgrass mixtures.

Three commercial Trichoderma products (Trichodex, Binab TF WP, and Rootshield) and the laboratory strain T. harzianum P1 were sprayed weekly onto greenhouse-grown strawberry plants during the flowering period in an attempt to reduce fruit disease caused by Botrytis cinerea and Mucor piriformis. None of the treatments affected the marketable yield of strawberries. Laboratory tests showed that at the mean temperature of the greenhouse (12°C), formulated conidia of the various Trichoderma strains required up to 96 h to germinate, and conidia of B. cinerea and M. piriformis isolated from greenhouse strawberries required 11 and 16 h, respectively. Furthermore, the commercially formulated conidia were much more subject to fungistasis under nutrient stress in vitro than were fresh conidia of the same strains. The nutrient sensitivity was not revealed when assaying germination on a standard nutrient-rich laboratory medium. Formulated conidia were also inferior to fresh conidia in capacity to clonize senescent strawberry leaves.

In the present study, the growth, dry matter partitioning and morphological characteristics and C exudation of two white clover cultivars, Norstar and AberHerald, were compared, under two temperature regimes (24/18°C and 12/6°C day/night) in a controlled temperature room. Root exudates collected from the two cultivars were also tested on two common soil types from northern Norway to determine the influence of the exudates on microbial activity in those soils. Plants grown at the higher temperatures had greater biomass and lower root:shoot ratio than those grown at the lower temperature regime. The plants growing in the higher temperature regime had a higher N content and concentration. Temperature significantly affected morphological characters and plants grown at the higher temperature had more leaves and growing points, and longer stolons than those grown at 12/6°C. Total organic C in the root exudates was determined on two occasions during the experiment. After 7 days, the concentration in the leachates from the plants at the higher temperature was significantly greater, but after 34 days, the concentrations were much more variable from plant to plant and no significant differences were seen. There were no significant differences in the rate of O2 uptake and utilisation by either the peat or mineral soils given exudates collected from plants growing at the cooler temperatures. In soils which were given exudates collected from plants growing at the higher temperatures, the rate of O2 utilisation by the mineral soil given the Norstar exudates was significantly lower than the other three combinations.
