16. Evaluation of supply chains and post-harvest losses of selected food commodities in Ethiopia
Sammanfattning : Supply chain management practices and losses in food value chains of three major food commodities in Ethiopia (milk, teff and warqe or enset) were evaluated in this thesis. Teff is a cereal, while warqe is a perennial plant from which the food products kocho and bulla are extracted. Teff, kocho and bulla are staple foods for many Ethiopians. LÄS MER
17. Population dynamics of the perennial weed species Sonchus arvensis L
Sammanfattning : Sonchus arvensis L. is a perennial weed that is widely prevalent in annual crops in northern Europe and can cause substantial yield losses. The abundance of S. arvensis has increased recently, primarily due to expansion of organic farming and increased use of reduced tillage. LÄS MER
18. Friend or Foe? Biocontrol interactions of Pythium oligandrum within the potato cropping system
Sammanfattning : The potato crop is a valuable but vulnerable food source on a global level. It is under constant pressure from destructive plant diseases such as early and late blight. Traditionally to control these diseases farmers have relied heavily on synthetic fungicide use. LÄS MER
19. The role of subsoil properties for phosphorus leaching in agricultural soils
Sammanfattning : Phosphorus (P) leaching from agricultural land is a large contributor to eutrophication of many surface waters and the Baltic Sea. Better knowledge of P sorption and release in the subsoil could enable the development of effective mitigation strategies for P leaching. LÄS MER
20. Nitrogen use efficiency and related functional traits in wheat : influence of genotype and environment
Sammanfattning : Efficient use of nitrogen (N) is essential to decrease negative impacts of agriculture on the environment. This thesis evaluated the nitrogen use efficiency (NUE) of various wheat varieties, identified traits associated with high NUE and investigated the gene NAM-B1 in relation to some of these traits.
