Nitrogen nutrition is key to grain yields. Phosphate and potash produce a healthy, vigorous stand. Hi-Bred professional for a maximum economic yield strategy based on the relationship between field status, yield expectation and nutrient prices. Start weed control early Until now, weed control has been a challenge in some western Canadian corn crops. Corn is a vigorous competitor that effectively shades out weeds once it has formed a canopy.
Research shows, however, that yields are best in crops that are weed-free through the early season.
Harvesting depends on end-use Harvesting strategies depend on how the corn crop will be used. Grain corn is usually harvested with a combine fitted with a grain head. While grain corn can be harvested above 30 per cent moisture, harvesting at lower moistures will reduce post-harvest drying costs. The distilling industry purchases corn at 14.5 per cent moisture. For most other applications, 15.5 per cent is considered a safe, long-term level to reduce risks of spoilage.
