This graph shows that a higher seeding rate that will ensure a stand of at least 60 plants per square metre (6 per square foot) will mature a lot earlier than a stand with 20-40 per square metre. A higher seeding rate is just one way to reduce the days to maturity for a late seeded canola field…

High cereal yields last year mean more residue issues this spring. If the drill cannot cut through or dig under the residue to place seed into soil, then some sort of residue management may be the lesser of two evils. We ran a survey the past two weeks asking Canola Watch readers for their thoughts on effective spring management for…

It’s mid May, so put away the soil thermometer. When you get the chance to seed, then seed. Seeding into warmer (8-10°C) soils will improve seed survival and have more seed emerging at the same time (as shown in the graph) but this needs to be balanced against the benefits of early seeding. To improve seed survival and speed of…

Early weed control is an important step in profitable canola production. Research on preseed weed control showed that early seeding was less important to yield than early weed control. Pre-seed weed control will manage weeds that emerge ahead of seeding, reducing crop competition for light, moisture and nutrients…

Applying a burnoff after seeding but before emergence is a risky option for those who want to get seeding. Consider the following risks with this practice…

Research shows that a pre-seed burnoff will result in higher yields versus no pre-seed burnoff. Walk fields to see what weeds are present and how fast they’re advancing. Seeding can begin fairly soon after a burnoff…

1. Date. Record the date and also the time of day that each crop was seeded. Comparing seeding dates, and cross referencing that with soil temperature and moisture conditions, can help determine future decisions with regard to ideal time of seeding and management steps that could be taken to reduce risks for early seeding. Time of day could be useful…

Need to make a last minute seed decision? Visit www.canolaperformancetrials.ca for canola variety comparisons for 2013 as well as 2012 and 2011. The online tool has data on yield, days to maturity, lodging and height for small plot and field scale sites across the Prairies. Use the various filters to refine a search by location, herbicide tolerance system, year and…

One goal in the Canola Council’s new strategic plan is to reach an average yield of 52 bu./ac. by 2025. This, along with acres holding at around 2012 levels, will achieve the production target of 26 million tonnes — which is the forecast market for Canadian canola by 2025. Here are five keys to achieving the yield target…
