Breeding for intercropping: the case of red clover persistence in grasslands
Ergon, Åshild Gunilla; Bakken, Anne Kjersti (Peer reviewed; Journal article, 2022-06-24)Legumes are important in sustainable agriculture and particularly so when they are intercropped with other species. In breeding programs, little attention is paid to their agronomic performance in species mixtures. In red ... -
Bunkers or round bales: Losses and silage quality with or without acid treatment of low dry matter grass crops
Randby, Åshild Taksdal; Bakken, Anne Kjersti (Peer reviewed; Journal article, 2021-05)Grass clover crops were harvested with or without application of 4 L/t of a formic- and propionic acid-based silage additive and ensiled in one bunker silo and 6 round bales per treatment in each of three harvests. The ... -
Controlling dietary cation-anion differences in forages by chloride fertilisation
Nesheim, Lars; Synnes, Olav Martin; Steen, Arvid; Langerud, Anne; Bakken, Anne Kjersti (Peer reviewed; Journal article, 2020-03-30)Rations with low to negative dietary cation-anion difference (DCAD) given to dairy cows before calving reduce the risk of hypocalcaemia (milk fever). Different strategies for increasing forage DCAD were investigated in ... -
Effect of acid based additive treatment of low dry matter grass crops on losses and silage quality in bunker silos
Randby, Åshild Taksdal; Bakken, Anne Kjersti (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 ... -
Effects of green manure herbage management and its digestate from biogas production on barley yield, N recovery, soil structure and earthworm populations
Frøseth, Randi Berland; Bakken, Anne Kjersti; Bleken, Marina Azzaroli; Riley, Hugh; Pommeresche, Reidun; Thorup-Kristensen, Kristian; Hansen, Sissel (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 integrated grassland renewal strategies on annual and perennial weeds in the sowing year and subsequent production years
Ringselle, Björn; Bakken, Anne Kjersti; Höglind, Mats; Jørgensen, Marit; Tørresen, Kirsten (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 ... -
Environmental Impact of Feeding with Infant Formula in Comparison with Breastfeeding
Andresen, Ellen Cecilie; Hjelkrem, Anne-Grete Roer; Bakken, Anne Kjersti; Andersen, Lene Frost (Peer reviewed; Journal article, 2022-05-24)Young children have unique nutritional requirements, and breastfeeding is the best option to support healthy growth and development. Concerns have been raised around the increasing use of milk-based infant formulas in ... -
Environmental impacts along intensity gradients in Norwegian dairy production as evaluated by life cycle assessments
Bakken, Anne Kjersti; Daugstad, Kristin; Johansen, Astrid; Hjelkrem, Anne-Grete Roer; Fystro, Gustav; Strømman, Anders Hammer; Korsæth, Audun (Journal article; Peer reviewed, 2017-09-18)The aim of the study was to explore whether and how intensification would contribute to more environmentally friendly dairy production in Norway. Three typical farms were envisaged, representing intensive production ... -
Forage production strategies for improved profitability in organic dairy production at high latitudes
Flaten, Ola; Bakken, Anne Kjersti; Lindås, Anitra; Steinshamn, Håvard (Journal article; Peer reviewed, 2019)The objective of this paper was to examine how cutting frequency, silage fermentation patterns and clover performance in grass-clover swards influence the use of inputs and profitability in an organic dairy system. A linear ... -
Forage yield and quality estimation by means of UAV and hyperspectral imaging
Geipel, Jakob; Bakken, Anne Kjersti; Jørgensen, Marit; Korsaeth, Audun (Peer reviewed; Journal article, 2021-03-18)This study investigated the potential of in-season airborne hyperspectral imaging for the calibration of robust forage yield and quality estimation models. An unmanned aerial vehicle (UAV) and a hyperspectral imager were ... -
Losses and grass silage quality in bunker silos compacted by tractor versus wheel loader
Randby, Åshild Taksdal; Halvorsen, Haakon Nordtveit; Bakken, Anne Kjersti (Peer reviewed; Journal article, 2020-04-27)The study aimed to explore whether an increase in bunker silage density obtained by turning to a heavier packing machine than a farm size tractor would reduce losses and improve grass silage quality and aerobic stability. ... -
NORNE, a process-based grass growth model accounting for within-field soil variation using remote sensing for in-season corrections
Hjelkrem, Anne-Grete Roer; Geipel, Jakob; Bakken, Anne Kjersti; Korsæth, Audun (Peer reviewed; Journal article, 2023-06-06)A process-based model was developed to predict dry matter yields and amounts of harvested nitrogen in conventionally cropped grassland fields, accounting for within-field variation by a node network design and utilizing ... -
Variation in rate of phenological development and morphology between red clover varieties: Implications for clover proportion and feed quality in mixed swards
Nadeem, Shahid; Steinshamn, Håvard; Sikkeland, Elin Halvorsen; Gustavsson, Anne-Maj; Bakken, Anne Kjersti (Journal article; Peer reviewed, 2019-05-28)Red clover (Trifolium pratense) grown in mixtures with grasses often constitutes a lower proportion of total yield in spring than in summer growth. A more even red clover proportion between the harvests would benefit forage ... -
