Effects of daytime or night-time grazing on animal performance, diurnal behaviour and enteric methane emissions from dairy cows at high latitudes
(Peer reviewed; Journal article, 2023-05-30)This study compared animal performance and enteric methane (CH4) emissions from dairy cows in a part-time grazing (PTG) system in northern Sweden. Twenty-four Nordic Red dairy cows were allocated to one of two treatments: ... -
Effects of dietary plant and animal protein sources and replacement levels on growth and feed performance and nutritional status of market-sized turbot (Scophthalmus maximus) in RAS
(Peer reviewed; Journal article, 2022-11-14)One part of aquaculture sustainability is reducing the environmental footprint of aquaculture feeds. For European aquaculture, this means finding feed ingredients that are produced within the economic community, and that ... -
Effects of elevation-dependent climate warming on intra- and inter-specific growth synchrony in mixed mountain forests
(Peer reviewed; Journal article, 2020-09-19)Spruce-fir-beech mixed forests cover a large area in European mountain regions, with high ecological and socio-economic importance. As elevation-zone systems they are highly affected by climate change, which is modifying ... -
Effects of Formic Acid Preservation of Fishbones on the Extractability of Ammonium Lactate–Acetate Soluble Calcium, Phosphorus, Magnesium, and Potassium
(Peer reviewed; Journal article, 2022-03-03)Fishbones contain significant amounts of plant nutrients. Fish residues may be preserved by acidification to pH < 4, which may affect the chemical extractability, and the plant availability of nutrients when applied as ... -
Effects of Grazing Abandoned Grassland on Herbage Production and Utilization, and Sheep Preference and Performance
(Journal article; Peer reviewed, 2018-05-29)Large areas of farmland are abandoned in Norway, which for various reasons are regarded as undesirable. Loss of farmlandmay have negative implications for biodiversity and ecosystem function and food production potential. ... -
Effects of grazing previously abandoned grassland on performance in sheep
(Grassland Science in Europe;Volume 21, Peer reviewed; Chapter, 2016)Large areas of cultivated grasslands have been abandoned in Norway and are no longer used for production. Knowing that access to spring and autumn pastures is a limiting factor for sheep farmers, this study aims at testing ... -
Effects of green manure herbage management and its digestate from biogas production on barley yield, N recovery, soil structure and earthworm populations
(Journal article; Peer reviewed, 2014-01)In repeatedly mown and mulched green manure leys, the mulched herbage contains substantial amounts of nitrogen (N), which may only slightly contribute to the following crops’ nutrient demand. The objective of the present ... -
Effects of growth control on yield and fruit quality of the apple cultivar ‘Rubin’
(Peer reviewed; Journal article, 2020-06-22)The effect of tree growth-control technologies on apple tree vegetative development, productivity and fruit quality was investigated with apple cultivar ‘Rubin’ on dwarf rootstock P 60 at the Institute of Horticulture, ... -
Effects of hair coat characteristics on radiant surface temperature in horses
(Peer reviewed; Journal article, 2019-11-29)Horse owners may lack knowledge about natural thermoregulation mechanisms in horses. Horses are managed intensively; usually stabled at night and turned out during the day. Some are clipped and many wear a blanket, practices ... -
Effects of heifers and sheep grazing on herbage production on a previously abandoned grassland
(Grassland Science in Europe;21, Chapter, 2016)Large areas of cultivated grassland are annually abandoned and no longer used for production in Norway. Such areas will over time be encroached by shrubs and trees, which is regarded as undesirable. We assessed plant ... -
Effects of integrated grassland renewal strategies on annual and perennial weeds in the sowing year and subsequent production years
(Peer reviewed; Journal article, 2023-03-14)Appropriate weed control measures during the renewal phase of temporary grasslands are critical to ensure high yields during the whole grassland lifecycle. The aim of this study was to determine which integrated grassland ... -
Effects of intensive biomass harvesting on forest soils in the Nordic countries and the UK: A meta-analysis
(Peer reviewed; Journal article, 2021-02-15)The use of biomass from forest harvesting residues or stumps for bioenergy has been increasing in the northern European region in the last decade. The present analysis is a regional review from Nordic and UK coniferous ... -
Effects of limited volatiles release by plants in tritrophic interactions
(Journal article; Peer reviewed, 2019-04-17)We introduce a mathematical model to describe the tritrophic interaction between crop, pest and the pest natural enemy where the release of Volatile Organic Compounds (VOCs) by crop is taken into account. The VOCs may be ... -
Effects of mild drought on the morphology of sun and shade needles in 20-year-old Norway spruce trees
(Journal article; Peer reviewed, 2019-02-28)Several studies have looked at how individual environmental factors influence needle morphology in conifer trees, but interacting effects between drought and canopy position have received little attention. In this study, ... -
Effects of model specification, short-run, and long-run inefficiency: an empirical analysis of stochastic frontier models
(Journal article; Peer reviewed, 2018-11-21)This paper examines the recent advances in stochastic frontier models and its implications for the performance of the Norwegian crop producing farms. Unlike the previous studies, we used a cost function in multiple ... -
