Our goal at seeding is to establish a target plant stand for canola of 7 to 10 plants per square foot to achieve the highest possible yield potential. Over the past two years we have experienced flea beetle and cutworm pressure in some of the farming areas. Using a low seeding rate to save on seed cost runs the risk of more input costs to protect the light plant stand. Extra passes of insecticide or herbicides can cut into your profit margins. Pioneer offers a free app (see above icon) that calculates canola seeding rates based on seed size, emergence and the conditions at seeding.

Coming back to establishing our goal of 7 to 10 plants per square foot, we need to keep in mind that speed of travel can impact depth. Research shows higher speeds can place seed beyond the ideal 1/2″ depth zone. This is due to more seed bounce and potential increase in soil disturbance resulting in varying seeding depth. Seeding depth outside the ideal range can increase risk of slower emergence and stand establishment, especially if pressure from disease and insects are a factor. Other considerations in canola stand establishment are soil temperature and seed placed fertilizer.
