Abstract
The performances of the plum rootstocks Plumina® Ferlenain, Ishtara® Ferciana, Jaspi® Fereley and the pentaploid open pollinated seedling of Mariana P 8-13 compared with St. Julien A as a standard, for the cultivars "Opal" and "Reine Claude GF 1119" were assessed in a field trial in western Norway at 60" North. This trial was one part of an international plum rootstock trial located in seven European countries and organized from INRA Bordeaux. Trees were planted in spring 1994; spaced 2.0 x 4.0 m and formed with a central leader as free spindles. Soil management was grass in the alleyways and herbicide strips 1-m wide along the tree rows. Tree vigour, yield, fruit size and yield efficiency were evaluated for the seven subsequent years. Tree size was significantly affected by the rootstocks. P 8-13 produced the largest trees for both cultivars as measured by trunk cross-sectional area. The smallest trees were produced on Plumina® Ferlenain for the cultivar `Opal" and on Jaspi® Fereley for `Reine Claude". The cultivar `Opal" was the most productive and gave three times larger crop than "Reine Claude" on average for the six cropping years. The "Reine Claude" trees came two years later into production than "Opal". There were small differences between the different rootstocks in productivity: However, the rootstock Plumina® Ferlenain produced significant lower crop than the other rootstock for `Opal". Trees on Jaspi® Fereley were the most yield efficient for `Opal" and Plumina® Ferlenain for `Reine Claude". The fruit sizes were in general medium to small for both cultivars and became little affected by the different rootstocks. The average fruit size was about 29 g for `Opal" and 22 g for `Reine Claude". Fruit quality characterized by the content of soluble solids was high for `Reine Claude" with average 20 % and 15 % for `Opal" and did not differ much between trees on the various rootstocks.
Report – Trade Facilitation through Equivalence and Mutual Recognition: The EU Model

Frode VeggelandAbstract
This report explores how equivalence and mutual recognition have been applied by the European Union (EU) in order to facilitate trade. The EU is of particular interest in this area because it has been in the forefront internationally with regard to applying these tools, both in its internal market project and in its external trade relations. The report includes an empirical mapping of EU’s experience with applying equivalence and mutual recognition as trade facilitating tools. The aim here is to increase the understanding of how these tools can be relevant and important in a wider global context, in particular with regard to food trade. Furthermore, based on this experience some of the challenges that countries are faced with when applying these tools are highlighted thus allowing some assessments of the prospects of and difficulties in achieving trade facilitation through these means. Chapter 2 includes an account of some of the regulatory approaches that the EU has pursued in its attempts at realising an internal market, from the adoption of common rules, to mutual recognition and the «Better Regulation» programme included in the Lisbon strategy. Chapter 3 discusses EU’s rules for third-country relations. Furthermore, some of EU’s mutual recognition and equivalence agreements are explored. In addition to these, Chapter 3 includes an account of one-way judgements of equivalence included in EU’s rules for imports of organic food and fishery products. Chapter 4 presents EU’s work and positions on equivalence and mutual recognition in the WTO and the Codex Alimentarius Commission. Chapter 5 includes an assessment of the EU’s experience with mutual recognition and equivalence. Finally, in Chapter 6 some conclusions and final remarks are made. […]

Abstract
Six cropping systems, ranging from conventional arable without livestock to organic livestock farming dominated by ley, have been compared in 1990 and 2004 in SE Norway. Ley in the crop rotation increased density and biomass of earthworms and channels in both organic and conventional systems. A ley proportion higher than 25 % only increased the density of channels. Among the arable systems, the organic system had a higher density and biomass of earthworms as compared to the conventional systems. Among the fodder systems, the optimised system had the highest density of earthworms in 2004, but there were no differences between these systems in earthworm biomass or density of earthworm channels.
