USask studies abiotic stressors for improved crop yields

Researchers from the University of Saskatchewan are investigating how the first frost impacts corn varieties, in the hopes of finding new ways to maximize crop yields.

Global warming is bringing longer growing seasons, allowing producers to expand the types of crops they cultivate. While this can be a benefit, a longer growing season increases the risk of environmental stressors, like frost and cool overnight temperatures.

Researchers from the University of Saskatchewan (USask) are investigating how the first frost impacts corn varieties, in the hopes of finding new ways to maximize crop yields.

“With global climate change, we are realizing that you can push the corn belt northward, so we’re wondering how we can enable the production of that crop by expanding the season,” said Dr. Karen Tanino, professor of abiotic stress physiology in the College of Agriculture and Bioresources.
