  1. 21. Nodulation and biomass development of yellow and blue lucerne under pH stress

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Katarina Boström; [2023]
    Nyckelord :lucerne; blue lucerne BL ; yellow lucerne YL ; E. meliloti; nodulation; pH;

    Sammanfattning : Approximately 77% of global arable land use is devoted to forage cultivation, which is the basis for animal production and global food security. Therefore a sustainable and biologically diverse forage cultivation is needed. Feed for cattle needs to contain a good balance between fibre, energy and protein. LÄS MER

  3. 22. Companion crops in winter oilseed rape : effects on nitrogen concentration, biomass, and prevalence of weeds at the end of autumn growth

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Stina Johansson; [2023]
    Nyckelord :biomass; companion crops; intercropping; legumes; nitrogen concentration; organic cultivation; weeds; winter oilseed rape;

    Sammanfattning : Intercropping can be used as a management system to promote higher yield as well as less weeds,diseases, and insect damage. Legumes are a commonly used companion crop (CC) in intercropping due to the benefit of nitrogen (N) fixation. LÄS MER

  4. 23. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Joseph Vernier; [2023]
    Nyckelord :Computational Fluid Dynamics; Fluid Mechanics; Numerics; Micro-climate modeling; Radiation; Crop modeling; Photovoltaic panels;

    Sammanfattning : The increasing demand for energy, depletion of fossil fuels, rising global warming, and greenhouse gas emissions have stimulated the need for widespread development and adoption of renewable energy sources (RES) worldwide. Among these sources, solar energy has emerged as a major contender to meet the growing demand. LÄS MER

  5. 24. Carabids as weed seed control agent : impact of soil cultivation on carabid weed seed regulation

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Ellen Dahlgren; [2023]
    Nyckelord :weed seed predation; weed seed bank regulation; weed seed predation strength; seed predation strength; carabid beetles; tillage; piecewise structural equation model;

    Sammanfattning : As weed seed predators, carabid beetles can regulate the weed seed bank within agricultural fields. Little is anyhow known about how weed seed bank regulation by carabids is affected by different tillage treatments with decreasing intensity, why this was here examined. LÄS MER

  7. 25. Tracking Optimization in Agrivoltaic Systems : A Comparative Study for Apple Orchards

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Maddalena Bruno; [2023]
    Nyckelord :Agrivoltaics; Optimization; Light sharing; Apple Orchards; Lantbruk; Optimering; Ljusdelning; Äppelodlingar;

    Sammanfattning : Agrivoltaic (APV) systems, based on the co-location of solar panels and crops, are an innovative solution to land-use conflicts that often arise between agriculture and energy production. Their optimal functioning starts with efficient management and sharing of light between solar panels and underlying plants. LÄS MER
