Control of Elymus repens by rhizome fragmentation and repeated mowing in a newly established white clover sward
Bergkvist, G.; Ringselle, B.; Magnuski, E.; Mangerud, Kjell; Brandsæter, Lars Olav (Journal article; Peer reviewed, 2017)Control of perennial weeds, such as Elymus repens, generally requires herbicides or intensive tillage. Alternative methods, such as mowing and competition from subsidiary crops, provide less efficient control. Fragmenting ... -
Control of perennial weeds in spring cereals through stubble cultivation and mouldboard ploughing during autumn or spring
Brandsæter, Lars Olav; Mangerud, Kjell; Helgheim, Marit; Berge, Therese W. (Journal article; Peer reviewed, 2017)Creeping perennial weeds are of major concern in organically grown cereals. In the present study, the effects of different timing of mouldboard ploughing with or without a preceding stubble cultivation period, on weeds and ... -
Effects of renewal time, taproot cutting, ploughing practice, false seedbed and companion crop on docks (Rumex spp.) when renewing grassland
Ringselle, Björn; Berge, Therese W.; Stout, Daniel; Breland, Tor Arvid; Hatcher, Paul E.; Haugland, Espen; Koesling, Matthias; Mangerud, Kjell; Lunnan, Tor; Brandsæter, Lars Olav (Journal article; Peer reviewed, 2019)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) ... -
Impact of projected climate change on workability, attainable yield, profitability and farm mechanization in Norwegian spring cereals.
Kolberg, Dorothée; Riley, Hugh; Persson, Tomas; Mangerud, Kjell (Peer reviewed; Journal article, 2019)In cold-temperate climate with high soil water content in spring, the farmer often faces the choice between topsoil compaction during seedbed preparation and delayed sowing, both of which may reduce attainable cereal yield. ... -
Influence of mechanical weeding and fertilisation on perennial weeds, fungal diseases, soil structure and crop yield in organic spring cereals
Brandsæter, Lars Olav; Mangerud, Kjell; Andersson, Lars; Børresen, Trond; Brodal, Guro; Melander, Bo (Peer reviewed; Journal article, 2020)There is a need both in organic farming and on farms using integrated pest management for non-chemical measures that control the perennial weed flora. The effect of mechanical weeding and fertilisation on perennial weeds, ... -
Kunnskapsstatus - bedre agronomi
Bakken, Lars; Krogstad, Tore; Uhlen, Anne Kjersti; Bjugstad, Nils; Bakken, Anne Kjersti; Grønlund, Arne; Hauge, Atle; Hoel, Bernt; Korsæth, Audun; Riley, Hugh; Endrerud, Hans Christian; Mangerud, Kjell (Bioforsk Rapport, Research report, 2010)Denne rapporten er en utredning av kompetansegrunnlaget for bedre agronomi for å møte landbrukets klimautfordringer. Utredningen er gjort på oppdrag for Norges forskningsråd av Bioforsk, UMB og Høyskolen i Hedmark. Utredningen ... -
Mekaniske tiltak med og uten reduserte doser av glyfosat som alternativ til tradisjonell glyfosatsprøyting i vårkorn
Brandsæter, Lars Olav; Mangerud, Kjell; Hjerpaasen, Vegard; Tørresen, Kirsten (Journal article, 2021) -
Rhizome Fragmentation by Vertical Disks Reduces Elymus repens Growth and Benefits Italian Ryegrass-White Clover Crops
Ringselle, Björn; Bertholtz, Erik; Magnuski, Ewa; Brandsæter, Lars Olav; Mangerud, Kjell; Bergkvist, Göran (Journal article; Peer reviewed, 2018)Tillage controls perennial weeds, such as Elymus repens, partly because it fragments their underground storage organs. However, tillage is difficult to combine with a growing crop, which limits its application. The aim of ...
