  1. 1. Underlying mechanisms behind nitrous oxide emissions in oilseed radish, Raphanus sativus var. oleiformis, and Phacelia tanacetifolia

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Annika Swensson Källén; [2023]
    Nyckelord :nitrous oxide; glucosinolates; greenhouse gases; oilseed radish; Phacelia tanacetifolia; cover crops; labile C;

    Sammanfattning : Greenhouse gases are a driving force of climate change and the annual greenhouse gas emissions were higher between 2010-2019 than any other time in human history (Skea et. al. 2022). LÄS MER

  3. 2. Emissions of nitrous oxide associated with frost killed cover crops

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Felicia Olofsson; [2022]
    Nyckelord :Nitrous oxide; cover crops; greenhouse gases; freeze-thaw cycles;

    Sammanfattning : Agriculture is responsible for approximately 80% of anthropogenic emissions of the potent and long-lived greenhouse gas nitrous oxide (N2O). N2O emissions from agricultural soils are characterized by high temporal and spatial variability and often peak in short bursts related to events such as precipitation, fertilization and soil thawing.

  4. 3. Cover crops for plant protection : Cover crops for control of root pathogenic Plasmodiophora brassicae and the root parasitic nematodes Pratylenchus penetransand Meloidogyne hapla

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Izabella Lundborg; [2022]
    Nyckelord :Clubroot disease; plant parasitic nematodes; Lupinus angustifolius; Avena strigosa; Phacelia tanacetifolia; Lolium perenne; Solanum lycopersicum; Brassica napus;

    Sammanfattning : Root pathogens and parasites are an increasing problem in agricultural and horticultural production. The soil borne pathogen Plasmodiophora brassicae is one of the major pathogens in oilseed rape production and the plant parasitic nematodes (PPNs), Pratylenchus penetrans and Meloidogyne hapla infest important crops such as carrot, potato and strawberry.

  5. 4. Flower visitors in flower strips : which flower species are the most attractive?

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Ida Johansson; [2021]
    Nyckelord :pollinators; hoverflies; bumblebees; flower strips; honeybees;

    Sammanfattning : Flower strips can be a helpful tool when it comes to increase pollination, pest control and farmland diversity. Different flower species have different attributes such as colour, odours and depth of the corolla tubes and this determines which beneficial organisms will be attracted to that flower species.

  7. 5. Summer cover crops after harvest of early potatoes control seed weeds

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Amanda Ahlqvist; [2019]
    Nyckelord :cover crops; buckwheat; Fagopyrum esculentum; sudangrass; Westerwoldisch ryegrass; crimson clover; Persian clover; seed weeds; weed management; marigold; tagetes; early potatoes; potatoes;

    Sammanfattning : To reduce pesticides and find greener alternatives for weed management in crop production has been a big issue worldwide. In Sweden, the Board of Agriculture has developed grants for farmers who use e.g. cover crops and new and greener strategies (e. LÄS MER
