Temperature Impacts Corn Emergence

By Pam Knox

If you plant corn or work with farmers who do, you are probably well aware of the importance of watching soil temperatures before you plant. But if not, you might be interested in these Indiana PrairieFarmer stories that describe how soil temperature and moisture can affect corn germination and emergence. Farmers need to be aware of not only current soil temperature but also the forecasts for both the daily temperature range and potential rainfall. The soil temperature range is also affected by both the soil type and whether it is no-till or has a lot of debris on the surface. If the temperatures get too low, the seed takes a long time to germinate and emerge from the ground, causing spotty field coverage.

Developing disease resistance in new wheat varieties

Video: Developing disease resistance in new wheat varieties


Dr. Colin Hiebert, research scientist with Agriculture and Agri-Food Canada – Morden, is focused on developing new tools that wheat breeders can use to improve, diversify and strengthen disease resistance in new wheat varieties. This includes new genomic tools that address resistance to five diseases including: Fusarium head blight, leaf rust, stripe rust, stem rust and common bunt.

Learn more about how research conducted at AAFC-Morden will impact wheat variety development, production and profitability for the future. This research is part of the Canadian National Wheat Cluster and funding is provided through the Sustainable Canadian Agricultural Partnership, Agriculture and Agri-Food Canada, Alberta Grains, Sask Wheat, Manitoba Crop Alliance, Western Grains Research Foundation and Canadian Field Crop Research Alliance.
