  1. 6. Biologisk bekämpning av potatiscystnematoder : några biologiska bekämpningsorganismer och deras potential för svenskt bruk

    University essay from SLU/Dept. of Ecology

    Author : Sabina Juhlin Munoz; [2023]
    Keywords : tillsättande biologisk bekämpning; Globodera; potatiscystnematoder; svampar; bakterier; parasitism; antibios; Trichoderma harzianum; Bacillus thuringiensis;

    Abstract : Potatiscystnematoderna (PCN) Globodera pallida (vit potatiscystnematod) och G. rostochiensis (gul potatiscystnematod) är sedentära endoparasiter på potatis som kan orsaka stora skördeförluster i potatisodlingar. Båda arterna av PCN är även klassade som karantänskadegörare i Sverige. READ MORE

  3. 7. The potential nitrous oxide emissions in a permanent grassland chronosequence

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Sandra Lillsjö Kronblad; [2023]
    Keywords : nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

    Abstract : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

    Author : Clara Kihlstrand; Linnéa Frisk; [2023]
    Keywords : Markhälsa; reducerad jordbearbetning; ; Conservation Agriculture; plöjning; mellangröda; höstvete; aggregatstabilitet; daggmaskar; pH; dragkraft; infiltration; vattenhalt;

    Abstract : Metoderna att odla jordbruksmark är många. Dessa odlingssystem påverkar markstrukturen och markhälsan på olika vis. Markhälsa är ett begrepp som blir allt viktigare. Under 2023 kommer EU med nya markdirektiv som ska säkra långsiktig odling och hjälpa till att nå klimatmålen. READ MORE

  5. 9. Biological control of verticillium stem striping disease on oilseed rape : fungi as friends and foes

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : André Åbonde; [2023]
    Keywords : Biological control; Oilseed rape; Clonostachys rosea; Verticillium longisporum; Verticllium stem striping disease;

    Abstract : The cultivation of oilseed rape faces challenges caused by pests and pathogens, and soil-borne pathogens such as Plasmodiaphora brassicae (clubroot) are among the main causes of disease. Verticillium longisporum is another soil-borne pathogen, which causes the verticillium stem striping disease in Brassica plants, including oilseed rape. READ MORE

  6. 10. Nodulation and biomass development of yellow and blue lucerne under pH stress

    University essay from SLU/Dept. of Crop Production Ecology

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

    Abstract : 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. READ MORE
