Consider seed size when targeting optimum plant stand

Key result: Seeding rates should be established based on 1,000-seed weight, using an on-line seeding rate calculator or on-line apps. Project title, Principal investigator: “Seed size and seeding rate effects on canola yield and quality,” Neil Harker, Agriculture and Agri-Food Canada Lacombe Funding: Alberta Canola, MCGA, SaskCanola, CCC, AAFC, GF2 Recent surveys indicate that approximately...

Ideal seeding speed depends on drill, conditions

An even seeding depth across all rows will improve canola uniformity and seed survival, but the seeding speed to achieve this consistency will depend on the drill, soil type and field conditions. It helps to run your own tests.

High rates of parasitism on diamondback moth larvae

Key result: This study continued work initiated by earlier research which showed that parasitism of diamondback moth larvae and pupae can be relatively high early in the season. Canola producers are encouraged to carefully monitor populations, waiting a few days after nominal thresholds are reached to provide beneficial insects an opportunity to control larvae and...

Speed one factor in lower harvest losses

Brent Lensen offered two canola fields for a study measuring canola harvest loss. His losses were lower than study’s average – possibly due to his 3-mph combine ground speed.

Science

Identification of superior crop rotations

Key Result: The southeast Peace region has the highest intensity of canola acres and short canola rotations in the western Canadian Prairies. However, this study suggests that this may not be the best choice for growers in terms of long term yield, cropping system sustainability, soil moisture use, root health and economics. Project Title, Principal...
