Identification and genetic mapping of resistance genes against Canadian pathotypes of Plasmodiophora brassicae in Brassica rapa and Brassica napus
DownloadFall 2022
Clubroot (Plasmodiophora brassicae) is an important disease of canola/rapeseed (Brassica napus) and other crucifers. In this study, resistance loci/genes effective against P. brassicae pathotypes 2B, 3A, 3D, 3H, 5C, 5X and 8J were identified and mapped via genotyping-by-sequencing, QTL analysis,...

Nutrient limitation of periphyton in agricultural streams: Implications for watershed management
DownloadSpring 2021
Freshwater streams are ecologically important as sources of habitat, unique biodiversity, and valued ecosystem services. Yet, stream health can be threatened by intensified nutrient loading derived from adjacent anthropogenic land-uses such as agricultural and municipal developments. Since algal...

Perceptions of Science and Expertise Among Alternative Ranchers in Alberta, Canada: A Qualitative and Actor-Network Analysis
DownloadFall 2021
Dlusskaya, Kira Konstantinovna
Raising animals has been an important aspect of human food systems for millennia, but with growing climate concerns, the management of animal agriculture, including beef production, needs to adhere to environmental best practices. Determining what these practices are has been the subject of much...

Improving Verticillium longisporum inoculation protocols and quantifying canola yield losses
DownloadSpring 2024
Verticillium stripe, caused by Verticillium longisporum, is an emerging soilborne disease of the Canadian canola (Brassica napus) crop. This study aimed to refine techniques for inoculating the pathogen on canola and to quantify its impact on hybrid canola yield under greenhouse and field...

Fall 2017
Since European settlement of the Canadian Prairies there has been substantial loss of wetlands. This loss occurs in large part due to drainage by private agricultural operators seeking to boost the productivity of their land. Policy makers now seek not only to conserve wetlands and prevent...

Assessment of current and future needs for entomological extension in agriculture in Alberta
DownloadSpring 2024
Recent changes to the structure of agricultural extension in Alberta have raised concerns about the effectiveness and efficiency of the system. There is a need to evaluate the effectiveness of the current agricultural extension system to identify opportunities for growth and collaboration....

Assessing spider (Araneae) diversity and pitfall trap retention in canola (Brassica napus L.) agroecosystems in north-central Alberta, Canada
DownloadFall 2024
Little is understood about the role of spiders (Araneae), their community composition, and predator-prey interactions in canola agroecosystems. Understanding these relationships may inform management decisions to effectively use spiders as biological control agents against insect pests. In...

Factors Influencing Verticillium Stripe in Canola: Blackleg Interaction, Host Resistance, and pH
DownloadFall 2024
Verticillium stripe, caused by Verticillium longisporum, is emerging as an important disease of canola (Brassica napus) in Canada. This thesis aimed to enhance understanding of potential interactions between Verticillium stripe and blackleg (Leptosphaeria maculans), assess the influence of pH on...

Biomass partitioning in canola (Brassica napus) and the characterization of leaf anatomical structures
DownloadFall 2024
Canola is the predominant crop grown on the Canadian Prairies, contributing about $26.7 billion to the economic activities per year in Canada. In 2023, Canada produced approximately 18.3 million tonnes of canola; however, the Canola Council of Canada set a goal of producing 26 million tonnes by...

Perennial Forage Polycultures and Organic Amendments Drive Soil Carbon Sequestration and Organic Matter Stabilization: Results After 90 Years of Management at the Breton Plots
DownloadFall 2024
Increasing agricultural intensification threatens to strain already degrading global soil resources while simultaneously escalating anthropogenic greenhouse gas emissions. Loss of soil organic matter (SOM) from agroecosystems is a major cause of soil degradation and a source of considerable...
