Xanthoria calcicola (Teloschistaceae, Ascomycota) still present on bark in Sweden
(Journal article; Peer reviewed, 2016)For almost twenty years Xanthoria calcicola was considered extinct on bark in Sweden. Here, we report X. calcicola growing on bark at 14 localities in Skåne, southernmost Sweden. In total, ca 300 thalli were observed on ... -
Yield and herbage quality from organic grass clover leys—a meta-analysis of Norwegian field trials
(Journal article; Peer reviewed, 2016-12)A meta-analysis based on experiments in organically cultivated grasslands in Norway was conducted to quantify the effects of management factors on herbage yield and feed quality. A dataset was collected that included 496 ... -
Yield Estimates by a Two-Step Approach Using Hyperspectral Methods in Grasslands at High Latitudes
(Journal article; Peer reviewed, 2019-02-16)Ruminant fodder production in agricultural lands in latitudes above the Arctic Circle is constrained by short and hectic growing seasons with a 24-hour photoperiod and low growth temperatures. The use of remote sensing to ... -
Yield increases due to fungicide control of leaf blotch diseases in wheat and barley as a basis for IPM decision-making in the Nordic-Baltic region
(Peer reviewed; Journal article, 2020-07-28)Fungal plant diseases driven by weather factors are common in European wheat and barley crops. Among these, septoria tritici blotch (Zymoseptoria tritici), tan spot (Pyrenophora tritici-repentis), and stagonospora nodorum ... -
Yield predictions of timothy (Phleum pratense L.) in Norway under future climate scenarios
(Peer reviewed; Journal article, 2023-07-26)The perennial forage grass timothy (Phleum pratense L.) is the most important forage crop in Norway. Future changes in the climate will affect growing conditions and hence the yield output. We used data from the Norwegian ... -
Yield reductions in agricultural grasslands in Norway after springtime grazing by pink-footed geese

Yield uncertainty and milk supply response in two-tier price systems
(Journal article; Peer reviewed, 2017-01-30)In two-tier price systems, yield uncertainty creates incentives to overproduce quantity-restricted outputs even when prices for surplus output are very low. These incentives arise from precautionary motives against expected ... -
Yield, nitrogen recovery efficiency and quality of vegetables grown with organic waste-derived fertilisers
(Journal article; Peer reviewed, 2017-09-30)More sustainable production of high-quality, nutritious food is of worldwide interest. Increasing nutrient recycling into food systems is a step in this direction. The objective of the present study was to determine nitrogen ... -
