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 ... -
Effects of nano-sized zero-valent iron (nZVI) on DDT degradation in soil and its toxicity to collembola and ostracods
(Journal article; Peer reviewed, 2013-06)Nano-sized zero valent iron (nZVI) has been studied for in situ remediation of contaminated soil and ground water. However, little is known about its effects on organisms in soil and aquatic ecosystems. In this study, the ... -
Effects of nano-sized zero-valent iron on DDT degradation and residual toxicity in soil: a column experiment
(Journal article; Peer reviewed, 2013-07)Background and aims Nanoscale zero-valent iron (nZVI) application is a promising technology for degradation of chlorinated contaminants in soil. Plants also play an important role in soil remediation and nZVI should not ... -
The effects of pollinizers on pollen tube growth and fruit set of European plum (Prunus domestica L.) in a Nordic climate
(Peer reviewed; Journal article, 2021-07-15)Norwegian plum production is characterized by climatic limitations, different flowering time, deficiently of wholly-adapted cultivars and appropriate pollen donors for cultivars that can be grown in this region. This study ... -
Effects of post anaerobic digestion thermal hydrolysis on dewaterability and moisture distribution in digestates
(Journal article; Peer reviewed, 2019)Organic waste fractions such as sewage sludge, food waste and manure can be stabilized by anaerobic digestion (AD) to produce renewable energy in the form of biogas. Following AD, the digested solid fraction (digestate) ... -
Effects of Post-Harvest Elicitor Treatments with Ultrasound, UV- and Photosynthetic Active Radiation on Polyphenols, Glucosinolates and Antioxidant Activity in a Waste Fraction of White Cabbage (Brassica oleracea var. capitata)
(Peer reviewed; Journal article, 2022-08-17)Biosynthesis of phytochemicals in leaves of Brassica can be initiated by abiotic factors. The aim of the study was to investigate elicitor treatments to add value to waste of cabbage. A leaf waste fraction from industrial ... -
The effects of progress in genetics and management on intensities of greenhouse gas emissions from Norwegian pork production
(Peer reviewed; Journal article, 2021-12)The environmental sustainability of food production systems, including net greenhouse gas (GHG) emissions, is of increasing importance. In Norwegian pork production, animal performance is high in terms of reproduction, ... -
Effects of renewal time, taproot cutting, ploughing practice, false seedbed and companion crop on docks (Rumex spp.) when renewing grassland
(Journal article; Peer reviewed, 2018-12-05)Docks (Rumex spp.) are a considerable problem in grassland production worldwide. We investigated how different cultural management techniques affected dock populations during grassland renewal: (I) renewal time, (II) ... -
Effects of Rhizobacteria Application on Leaf and Fruit Nutrient Content of Different Apple Scion–Rootstock Combinations
(Peer reviewed; Journal article, 2022-06-18)The plant pomological characteristics and physiological behaviors of genotypes in modern apple cultivation could be different depending on the use of rootstock, changing growth ecology and application of biological control ... -
