  5. 4. 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

  7. 5. Våld i nära relation och socioekonomisk status : En kvantitativ studie av skillnader i brottsnivå mellan kommuner

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för socialt arbete och kriminologi

    Författare :Evelina Davidsson; Therése Stråle; [2023]
