1.000 kg hvidkløver pr. ha! Organic Eprints
Boelt, B..
Hvidkløver er én af vores mest dyrknings-usikre afgrøder. Regulering af plantebestand, skadedyrsbekæmpelse og gode bestøvningsforhold kan medvirke til at opnå et højere og mere stabilt frøudbytte.

Aktuelt nyt fra Danmarks JordbrugsForskning, 2001 Organic Eprints
Boelt, B.; Clausen, D.; Gislum, R.; Hansen, L.M..
Kvælstof er et værdifuldt næringsstof for opnåelse af et højt frøudbytte, men også i relation til justering af væksten i udlægsmarken. Desværre har mange frøavlere begrænset adgang til kvælstof – dels på grund af en kvælstofnorm, som er fastsat under den økonomisk optimale værdi og dels på grund af begrænset adgang til husdyrgødning på økologiske planteavlsbedrifter. I Forskningsprogram frøavl arbejdes med udvikling af en behovsbestemt gødningsstrategi for at opnå en bedre udnyttelse af den til rådighed værende kvælstofmængde. Imidlertid tyder igangværende forsøg på, at kvælstof findes i ’alternative kilder’ såsom frøgræshalm og grøngødningsafgrøder, men kan de udnyttes i frøavlen? En anden supplerende kvælstofkilde er en øget anvendelse af hvidkløver...

Biosafety data improving the regulation of Co-existence Organic Eprints
Boelt, B..
Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards. Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds. Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence.

Clover seed production - in organic and conventional cropping systems Organic Eprints
Boelt, B.; Tveden-Nyborg, S.; Hansen, L.M..
White clover (Trifolium repens L.) is an important component in grassland mixtures and as a green manure crop. Since Denmark has excellent conditions for white clover seed production and holds the position of the largest producer within the EU emphasis has been placed on developing an organic production of white clover seeds.

Coexistence between genetically modified, conventional and organic crops. Availability of organically produced seed of varieties adapted to organic production systems Organic Eprints
Boelt, B.; Deleuran, L.C..
To maintain the integrity of organic farming systems guidelines to ensure coexistence between genetically modified (GM), conventional and organic crops should be implied. Since seed is moved cross borders a regulatory system is need to allow for organically produced seed of varieties adapted to organic production systems being available to organic farmers both in developed and developing countries.

Det sværeste ved hvidkløver er afpudsningen Organic Eprints
Boelt, B..
Arealet med hvidkløver til frø var 3853 ha i 2004, hvilket er det største areal siden 1978, og generelt er udviklingen af de danske areal positiv. Følgerne af den afkoblede EU-støtte forventes at være neutral for hvidkløverfrøproduktionens vedkommende. Hos vores største konkurrent, New Zealand, har en øget mælkeproduktion medført en vigende frøproduktion af hvidkløver. Den new zealandske mælkeindustri har stor succes med eksport af tørmælk til Asien, og mælkeproducenterne presser planteavlerne i området Canterbury Plains, hvor hovedparten af New Zealands frøproduktion er placeret. New Zealand er dog fortsat verdens største producent af hvidkløverfrø. En del af produktionen er i øjeblikket under udflytning til Australien.

Dyrkning af hvidkløver til frø Organic Eprints
Boelt, B.; Hansen, L.M..
Frøudbyttet i hvidkløver er påvirket af en lang række dyrkningsfaktorer. I økologisk produktion har forsøg gennem de senere år vist, at skadedyr kan reducere frøudbyttet væsentligt. Umiddelbart findes ingen dyrkningsmæssige tiltag, som kan løse dette problem. Faktorer som plantetæthed har endvidere stor betydning for afgrødens udbyttepotentiale.

Effect of seed rate and row spacing in seed production of Festulolium Organic Eprints
Deleuran, L.C.; Gislum, R.; Boelt, B..
Establishment methods have proven to be of major importance for grass seed production. The objective of this research was to test the effect of different sowing techniques on plant establishment and the subsequent seed yield. Perennial ryegrass (Lolium perenne L.) is used as the model grass due to its large importance in Danish agriculture. In a three-year trial six different methods of under-sowing of perennial ryegrass in a spring barley cover crop were employed. Perennial ryegrass was either sown directly at different depths within the spring barley (Hordeum vulgare L.) rows or placed 2, 6 or 12 cm from the spring barley rows. Results of dry matter yield indicate that the best establishment of the grass occurred when placing the grass 6 or 12 cm from...

Establishment techniques in under-sown prennial ryegrass for seed production Organic Eprints
Deleuran, L.C.; Boelt, B..
Festulolium (X Festulolium) has shown a considerable yield potential as a fodder crop and as a direct effect the seed production area in Denmark has increased. The main aim for the present trial is a growing interest for festulolium in organic production systems and hence the requirements for organic produced seed. A 3-year study was conducted to determine the seed yield response in two different types of festulolium in respect to three seed rates (8, 12 and 16 kg ha-1) and three row spacings (12, 24 and 36 cm). The lolium type cv. Paulita was not affected by seeding rate or row spacing. In the tall fescue type cv. Hykor no significant difference in seed yields were found in respect to seeding rate but narrow row spacing 12 and 24 cm yielded more than 36...

Forage cuts as a by-product in organic seed production Organic Eprints
Deleuran, L.C.; Boelt, B..
A major problem in organic grass seed production on arable farms is to provide for a sufficient nitrogen supply. A nitrogen-fixing crop may be able to cover the nitrogen requirement - wholly or partly. However mixed cropping of a grass seed and a nitrogen-fixing crop is expected to reduce the establishment of the seed crop, especially for species that require a long establishment period. One way to achieve a satisfactory establishment of the seed crop can be to introduce an intervening year for cutting forage between cover crop harvest and seed harvest. This will enhance tillering, since the light supply for the undersown grass is increased after each cut. However excessive biomass will hinder drying of the crop at maturity and therefore the growth of the...

GM organisms threaten organic systems: towards sustainability, coexistence and organic seed Organic Eprints
Boelt, B.; Deleuran, L.C.; Phelps, B..
Until now commercial genetically modified (GM) crops – soy, corn, canola and cotton - and their products have not been successfully segregated from organic or conventional non-GM production systems. Where GM crops are grown, GM contamination may be inevitable. However, physical and legal control measures imposed before the introduction of GM crops may help protect organic standards, supply chain integrity, certification and client confidence, but this is not yet fully tested. IFOAM’s approach to its present position on GM crops may not be sustainable long term as several invasive technologies – GM organisms (especially pharma crops, animals and micro-organisms), nanoparticles, and food irradiation – all challenge organic standards and integrity

Tunnelproduktion af grønsagsfrø muliggør produktion af kvalitetsfrø i en række grønsagsarter, hvor frilandsproduktion i Danmark er opgivet. Tunnelproduktion kan være en spændende niche, hvor der er særligt høje krav til frøkvalitet og genetisk renhed.

Hvordan dyrker jeg økologisk hvidkløver - uden snudebillerne stjæler udbyttet? Organic Eprints
Hansen, L.M.; Boelt, B..
Hvidkløver til frø er én af vore mest dyrkningsusikre afgrøder - selv i konventionel produktion. Foruden problemerne med at opnå en passende plantetæthed, undgå ukrudt og få afgrøden skårlagt og høstet under gunstige vejrforhold, må man som økolog acceptere, at der er kløversnudebiller i marken, og at billernes larver ernærer sig af hvidkløverfrø!
