  1. 1. Stubbhöjdens betydelse för det mekaniska spillet vid vallskörd

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

    Författare :Jonas Gustafsson; Fredrik Olsson; [2023]
    Nyckelord :Slåttervall; skördehöjd; klipphöjd; fältförluster; avkastning; foder; foderproduktion; foderkvalité;

    Sammanfattning : Vall odlas vanligtvis antingen i renbestånd eller i blandbestånd med fleråriga baljväxter och gräsarter vilka nyttjas till slåtter eller bete. Vid skörd av vall till foder för nötkreatur är den näringsmässiga sammansättningen av stor vikt. LÄS MER

  3. 2. Appropriate experimental design and pre-commercial thinning regime in Norway spruce stands on former agriculture lands in Latvia

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Aksels Edgars Loks; [2020]
    Nyckelord :management regime; heureka; randomized complete block design; density; economical rotation age; land expectation value;

    Sammanfattning : Recent decades Latvian land usage has change and lot of unused agricultural lands has been reforested. These areas show difference by increased growth from typical forest land, because of this trait stands need different silvicultural treatments, implementation time and intensity. LÄS MER

  4. 3. Thinning strategies of birch in Latvia, with application in a newly established field experiment

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Dagnija Saicane; [2019]
    Nyckelord :silver birch; abandoned agriculture land; thinning; pruning; design;

    Sammanfattning : Birch (Betula pendula Roth) is an early successional species which, if grown in suitable soils with wise management, can have high and valuable production. Large-dimension birch-wood is used for saw logs and plywood production, but smaller ones for pulpwood and energy wood. LÄS MER

  5. 4. Phenotypic variation of Salix viminalis in well-watered and drought conditions

    Master-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Författare :Sye Ling Lee; [2012]
    Nyckelord :Salix viminalis ; Phenotypic correlation; Drought; Genotype x Environment interaction GxE ; Broad sense heritability H2 ;

    Sammanfattning : Background and aims Salix viminalis, which is a C3 perennial crop, is one of the promising candidates for bioenergy production. It is easy to propagate by stem cutting and is able to re-sprout after each harvest. In addition, S. viminalis can produce high biomass yield within a short time frame. LÄS MER

  7. 5. Effects of fresh or sun-dried cassava foliage on the growth performance of goats fed basal diets of gamba grass or sugar cane stalk

    Magister-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Bounthavone Kounnavongsa; [2010]
    Nyckelord :cassava foliage; gamba grass; goats; growth; sugar cane;

    Sammanfattning : The overall aims of this thesis were to study existing goat production systems in lowland Laos, to investigate the potential to intensify goat production by using locally available feed resources, such as sugar cane, as the basal diet, and supplementing with fresh and sun-dried cassava foliage as the major protein source in view of the lack of information concerning the risk of toxicity from feeding the fresh cassava foliage. Sixty goat farmers in four villages of Nongbok and Xe bangfai Districts in Khammuane Province were selected, and formal and informal interviews were used to get information about goat production systems.
