Environmental conditions during plant raising determine the yield potential of everbearing strawberries. We studied the effect of three rooting dates in the cultivars ‘Favori’ and ‘Murano’ in a greenhouse with 18 ℃ and 20-h long day and under outdoor conditions in Norway. The highest yield of 1.350 g/plant was obtained in ‘Favori’ plants rooted on 1 August and raised outdoors, being at level with ‘Favori’ plants produced in The Netherlands. High yields were mainly related to fruit size and less to fruit number, and determined by a complex three-factor interaction of rooting date, raising environment, and cultivar. The seasonal pattern of fruit flushes and off periods varied significantly between cultivars and treatments. The large first flush of high yielding ‘Favori’ plants was associated with a long off period, while the small first flush in ‘Murano’ resulted in a more even crop distribution. Earliness of ripening and berry harvest was superior in ‘Favori’, which had a larger share of its crop during the first half-season. We conclude that it is possible by choosing the right rooting date and raising environment to produce plants with the same high quality and yield potential under the cool Nordic conditions as those currently produced in Central Europe.

Det er dyrket korn i Nord-Norge siden sein steinalder og kornet var en viktig del av kostholdet. Etter andre verdenskrig ble kornarealet i nord kraftig redusert. Med klimaendringer og med en økt markedsinteresse, er korndyrking igjen blitt aktuelt i nord. En av de største utfordringene er finne egnede sorter for nordlige strøk, og i dette prosjektet har vi testet de sju gjenværende nordnorske sortene for å teste hvor tilpasset de er dagens klima. Selv om resultatene er usikre, mener vi at Dønnes bygg samt at Nordlys og Bode kan være aktuelle byggsorter i Nordland. I Troms og Finnmark kan dyrking av Nordlys bygg være interessant, samt at Bode og Dønnes kan være aktuelle byggsorter. Pol havre og Vågønes vårrug er de eneste sortene av havre og rug fra Nord-Norge. Disse kan være aktuelle for dyrking i nord. Pol havre kan spesielt være interessant for dyrking til fôr i Troms og Finnmark. Videre utprøving kan gi sikrere resultat.

The INTENSE project, supported by the EU Era-Net Facce Surplus, aimed at increasing crop production on marginal land, including those with contaminated soils. A field trial was set up at a former wood preservation site to phytomanage a Cu/PAH-contaminated sandy soil. The novelty was to assess the influence of five organic amendments differing in their composition and production process, i.e. solid fractions before and after biodigestion of pig manure, compost and compost pellets (produced from spent mushroom substrate, biogas digestate and straw), and greenwaste compost, on Cu availability, soil properties, nutrient supply, and plant growth. Organic amendments were incorporated into the soil at 2.3% and 5% soil w/w. Total soil Cu varied from 179 to 1520 mg kg−1, and 1 M NH4NO3-extractable soil Cu ranged from 4.7 to 104 mg kg−1 across the 25 plots. Spring barley (Hordeum vulgare cv. Ella) was cultivated in plots. Changes in physico-chemical soil properties, shoot DW yield, shoot ionome, and shoot Cu uptake depending on extractable soil Cu and the soil treatments are reported. Shoot Cu concentration varied from 45 ± 24 to 140 ± 193 mg kg DW−1 and generally increased with extractable soil Cu. Shoot DW yield, shoot Cu concentration, and shoot Cu uptake of barley plants did not significantly differ across the soil treatments in year 1. Based on soil and plant parameters, the effects of the compost and pig manure treatments were globally discriminated from those of the untreated, greenwaste compost and digested pig manure treatments. Compost and its pellets at the 5% addition rate promoted soil functions related to primary production, water purification, and soil fertility, and the soil quality index.
