Across much of Western Canada, corn is using the impressive results of the last five years as a springboard to become a go-to crop on even more farms. So despite this year’s pricing worries, and despite all the talk of a potential over-supply of the crop, it’s a choice that more growers are loyal to.
The lesson from the East is that when a farm opts for corn, it isn’t just choosing a crop to grow. It’s choosing a way to structure and grow that farm. It’s choosing a future.
In this first edition of our “What’s new in Western corn hybrids,” we went to the companies for a quick summary of the latest hybrids and technologies.
Some companies differentiate their listings between grain and silage hybrids. Others talk differently of their latest technologies. It’s hard to be absolutely consistent in how we summarize them.
As always, we strive to make this list as comprehensive as possible, although, of course, it’s still important to discuss your seed and planting decisions with your dealer or seed company representative.
Also take note of the following abbreviations: CHU means corn heat units; RM is relative maturity.
1756VT2P/RIB is an early introduction that features a fixed-ear type suited for medium- to high-stand populations. 1756VT2P/RIB flowers in the mid-range of the maturity set, setting it up for good quality grain.
