Economic optimal nitrogen rate variability of maize in response to soil and weather conditions: Implications for site-specific nitrogen management
(Peer reviewed; Journal article, 2020-08-21)The dynamic interactions between soil, weather and crop management have considerable influences on crop yield within a region, and should be considered in optimizing nitrogen (N) management. The objectives of this study ... -
Economic performance and efficiency determinants of crop-producing farms in Norway
(Journal article; Peer reviewed, 2018)Purpose – The purpose of this paper is to explore the economic performance of Norwegian crop farms using a stochastic frontier analysis. Design/methodology/approach – The analysis was based on a translog cost function and ... -
Economy of forage-based cattle beef and milk production
(NIBIO-rapport;7(60) 2021, Research report, 2021-03)For nokre av driftsystema vi granska i SusCatt-prosjektet undersøkte vi nærmare korleis ein overgang til meir grovfôrbasert fôring kan ha å seie for lønnsemda. Fem SusCatt-system blei vurdert, inkludert arbeidet i Sverige ... -
Educational Strategies in Cultural Landscapes. Are we complying with the Faro Convention?
(Peer reviewed; Journal article, 2022-07-22)The Faro Convention underlined the importance of educational initiatives related to heritage. This paper focuses on the educational dimension of landscape, as a means to better facilitate its social acceptance and hence ... -
Effect of acid based additive treatment of low dry matter grass crops on losses and silage quality in bunker silos
(Peer reviewed; Journal article, 2021-05)The large surface area of bunker silos imposes challenges with heating caused by plant respiration during initial ensiling. This study aimed to explore if application of a formic- and propionic acid-based additive would ... -
The effect of climate variability in the efficacy of the entomopathogenic fungus Metarhizium acridum against the desert locust Schistocerca gregaria
(Peer reviewed; Journal article, 2022-05-09)Despite substantial efforts to control locusts they remain periodically a major burden in Africa, causing severe yield loss and hence loss of food and income. Distribution maps indicating the value of the basic reproduction ... -
Effect of combined seasonal coverage on northern production of strawberry (Fragaria ananassa Duch)
(Journal article; Peer reviewed, 2017)Two field trials with five strawberry cultivars planted on a woven black polyfibre ground cover sheet with or without translucent sheet plant coverage during winter and the growing season as combined treatments were started ... -
Effect of grassland cutting frequency, species mixture, wilting and fermentation pattern of grass silages on in vitro methane yield
(Peer reviewed; Journal article, 2023-03-23)Mitigating enteric methane (CH4) emissions is crucial as ruminants account for 5% of global greenhouse gas emissions. We hypothesised that less frequent harvesting, use of crops with lower WSC concentration, ensiling at ... -
Effect of maturity stage at harvest and kernel processing of whole crop wheat silage on digestibility by dairy cows
(Journal article; Peer reviewed, 2019)The study aimed to explore whether digestibility by cows of whole crop wheat silage harvested at two different dough stages of maturity was impaired due to its content of whole kernels. Wheat was harvested at early (ED) ... -
The effect of quota portfolio composition on optimal harvest strategy and profitability in a multi-species fishery
(Peer reviewed; Journal article, 2023-09-04)The benefits of individual vessel quota (IVQ) management in terms of improved harvest strategy and profitability are well recognized, but there is less focus on how different components of a quota portfolio can influence ... -
