The growth of corn acres continues to rise across Western Canada. Growers are using corn for various end uses, such as, grain corn for feed and fuel, silage corn for livestock, high moisture corn and grazing corn.
In order to grow a successful corn crop in Western Canada, you need to understand these key factors:
Corn Hybrid Selection
Fertility & Placement
Corn Heat Units (CHU)
Weed Control in Corn
Targeted Seeding Rate
Grain Dry Down
Harvest & Corn Staging
One of the most important factors is hybrid selection. Your Pioneer Hi-Bred sales representative can provide you with excellent information on agronomics and a recommendation on which corn seed product to choose for your area. Below is a list of Pioneer® brand corn seed products available in Western Canada.

CORN HEAT UNITS
DuPont Pioneer assigns corn heat unit (CHU) values to help position hybrids in the field. Corn heat units are a system of relatively ranking hybrids for their maturity as determined by the level of moisture a hybrid has at harvest.
Look at the corn heat unit rating of the hybrid you are considering and the physiological maturity for your area (see maps below) to best determine whether a hybrid can be safely planted on your farm. Depending on the end purpose of your corn crop, you must select an appropriate heat unit corn to achieve the desired maturity.
When selecting corn hybrids for your local conditions, it is best to work with someone that understands the area. That person is your local Pioneer Hi-Bred sales representative.
