Genetics will reduce harvest losses

A recent study by Andrea Cavalieri with the University of Manitoba found that pod shatter is primarily impacted by genotype, while environment is the dominant driver for pod drop.
Key practice: Canola varieties with pod shatter tolerance have arrived. Pod shatter tolerance adds more flexibility for harvest timing, allowing crops to stand longer with fewer losses. Key research: Cavalieri, A., University of Manitoba, et al. “Pod Drop and Pod Shatter Are Not Closely Related in Canola.” Crop Science (2014). Gan, Y., Agriculture and Agri-Food...

Target seven to 10 plants per square foot

Key practice: Target a population of at least seven plants per square foot to maintain yield potential for canola. This target will allow for some plant mortality due to post- seeding stresses without dropping below the minimum five plants per square foot required for canola yield potential.

Top dress if deficiencies are likely

Key practice: In Western Canada where the growing season is short, the ideal practice is to apply all fertilizer at the time of seeding. However, if shortages are expected or crops are showing deficiencies, soil-applied applications of nitrogen or sulphur fertilizer after emergence will likely provide an economic benefit. Key research: Guy Lafond, Agriculture and...
