Achieving 7 to 10 plants per square foot can mean some high seeding rates for seed with large thousand seed weights (TSW). Therefore, going much above 6 lb./ac. is not generally recommended — regardless of TSW. The better agronomic strategy is to put effort into increasing seed survival rather than invest in a higher seeding rate…

Growers uncertain about which canola seeding rate to use should start with 5 lb./ac., then tweak. See the full article on this topic…

For growers who want to keep things simple, a standard seeding rate of 5 lb./ac. should meet the basic needs of stand establishment — as long as all other steps for a good stand are followed. Growers who want a seeding rate that establishes 7 to 10 plants per square foot — 4 plants is about the minimum but you…

With an average seeding rate of 5 lb./ac., an average thousand seed weight (TSW) of 5 grams, and 50% seed survival rate, the result is only 5.2 plants per square foot. This doesn’t leave much margin for error — especially given the ideal target is 7 to 10 plants per square foot. Seed with a lighter TSW can improve your…

The ideal canola stand will have 7-10 plants per square foot. Canola needs a minimum of 4-5 plants per square foot, on average, to reach its yield potential. A few extra plants improves the chance of hitting yield targets, and allows for some plant loss to insects and disease. Canola with plant populations below 4-5 per square foot can still…

If plant counts are lower than you expected based on your seeding rate, taking time now to figure out why will help fix the problem for next year. Use the Canola Diagnostic Tool to help. While scouting, look for the following, which will help with the diagnosis:…

For the variety you have chosen to reach its full potential, it is important to get an adequate number of healthy plants growing. Agriculture and Agri-Food Canada surveys of canola fields in Alberta in 2010 and Saskatchewan fields in 2012 found that only about half of fields achieved an average of 5 plants or more per square foot. Canola plant…
