OMAF Field Crop Report – Sept. 12

Canola/Edible Beans: Brian Hall

Canola harvest ranges from 5-70% complete. Yields range from 1700 to 3400 lbs./ac with most fields yielding 2000 lbs./ac or better. Quality has been good. Do not delay swathing or harvesting as canola is subject to high shattering losses from wind, heavy rain, or hail. Uneven maturity is the biggest challenge. Optimum stage for swathing is 60% seed colour change. There is 8-10% yield advantage to swathing at 50-60% seed colour change compared to 30-40% seed colour change. If frost is forecast and the crop is not ready for harvest, swathing early to reduce green seed must occur about 3 days prior to the frost. Green seed caused by frost damage will not degreen in the swath.

Edible bean harvest has been delayed in many areas due to wet weather and slow maturity of the crop. Yields to date have ranged from 17-28 cwt./ac. Staging of fields requiring a pre-harvest herbicide application should be based on the green immature areas of the field to avoid quality issues.

Cereals: Peter Johnson

Spring cereal harvest drags on, with frequent showers frustrating growers. Yields and quality continue to range widely, from best ever to well below average. Producers growing winter barley to replace spring barley should plant immediately. Winter hardiness of winter barley is less than winter wheat and needs to be planted earlier to offset this weakness.

Winter wheat planting is underway in the shorter season areas and will start in earnest next week. If planting on corn silage ground, a moderately resistant (MR) variety is required to be eligible for Production Insurance. Do not forget fall weed control around wheat planting: fall weed control offers many options that spring weed control cannot, with much better control of perennials and winter annuals. Where control of glyphosate resistant Canada Fleabane is needed, Eragon tankmixed with glyphosate is the best option.

Cover crops oats have much less growth than last year, due to a lack of moisture. Growth of oats for a forage crop following wheat is particularly disappointing, with oats heading and barely knee high. Red clover stands and growth have been excellent in most regions, adding some excitement back into seeding clover under wheat.
