  1. 6. Integrating legumes in mixed crop-livestock systems in east Africa: Farmers' perceptions, ecosystem services and support for decision making

    Författare :Tarirai Muoni; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Challenges faced by smallholder farmers in east Africa include limited access to inputs, small farm sizes, and erratic rainfall patterns. Legume intensification and species diversification have been recommended for improving food and nutritional security, controlling soil erosion, improving soil fertility, supplying income and providing fuel.

  3. 7. Ecology and genomics of microorganisms reducing the greenhouse gas N₂O : examples from the rhizosphere

    Författare :Daniel Graf; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Nitrous oxide (N₂O) is a potent greenhouse gas and the major ozone depleting substance in the stratosphere. One major source of N₂O is incomplete denitrification, whereas the only known tropospheric sink of N₂O is the microbial enzyme nitrous oxide reductase. LÄS MER

  4. 8. Agroforestry systems with trees for biomass production in western Kenya

    Författare :Hans Sjögren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Low agricultural production and a decline in fuelwood resources are serious constraints for subsistence smallholder farmers in western Kenya in the sub-Saharan African region. Furthermore, low soil fertility and general environmental degradation has contributed to the build-up of the parasitic weed Striga hermonthica. LÄS MER

  5. 9. Banana xanthomonas wilt and potato bacterial wilt in Rwanda : biology, risk factors and farmers’ awareness

    Författare :Florence Uwamahoro; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Banana (Musa spp.) and potato (Solanum tuberosum) are important food and cash crops worldwide as they contribute to food security and income generation for farmers. Despite their importance, banana and potato do not reach their potential production due to a number of limitations, including pests and diseases. LÄS MER

  7. 10. Revisiting push-pull technology: Below and aboveground mechanisms for ecosystem services

    Författare :Aneth Bella David; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Push-pull technology is an effective and ecological solution to suppressing major Lepidopteran pests of cereals, in particular stem-borers (Busseola fusca, Chilo partellus), the fall armyworm (Spodoptera frugiperda) and the parasitic weed Striga. The technology exploits plant-insect interactions in intercropping practices to manage the pests, increasing productivity while maintaining ecosystem resilience. LÄS MER
