In manured fields, corn may need little fertilizer, although even in these fields, phosphate applied with or near the seed will produce more vigorous seedlings. 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.
