Cropping system rotation in combination with harvest weed seed control for wild oat (<i>Avena fatua</i>) management Open
Wild oat is a significant weed of cropping systems in the Canadian Prairies. Wild oat resistance to herbicides has increased interest in the use of nonchemical management strategies. Harvest weed seed control techniques such as impact mill…

Precipitation and nitrogen management are key drivers of cropping system productivity in the Canadian prairies Open
The performance of cropping systems is a function of crop and management practice interaction in a given growing environment. However, the critical factors affecting productivity remains unclear under varying climate conditions. We conduct…

Spring wheat agronomic and quality responses to a genotype × environment × N source and management systems approach Open
Yield and quality improvements in Canada Western Red Spring (CWRS) wheat ( Triticum aestivum L.) are increasingly difficult to attain, which behooves a systems approach to unlock genotype (G) × environment (E) × management (M) synergies. T…

Using integrated weed management systems to manage herbicide-resistant weeds in the Canadian Prairies Open
Although herbicides have been a dominant and effective weed control strategy for decades in Western Canada, herbicide resistance and the lack of new modes of action have resulted in weed management challenges. Integrated weed management st…

Integrating enhanced efficiency fertilizers and nitrogen rates to improve Canada Western Red Spring wheat Open
Granular urea fertilizer applied at planting is prone to nitrogen (N) losses in certain environments. Enhanced efficiency fertilizers (EEFs) are developed to mitigate losses and optimize plant uptake. To determine the benefits of EEFs in g…
