Effect of seed quality on the performance of hybrid Argentine canola in early- and late-seeded plots with conventional and minimum tillage

Researcher: Bob Elliott, Larry Mann and Owen Olfert, Agriculture and Agri-Food Canada, Saskatoon, SK

Project Code: CARP 2004-14.5

Final Report: November 2007

Summary: The objective of this study was to investigate the effect of seed quality on the performance of hybrid Argentine canola in early- and late-seeded plots with conventional tillage and minimum tillage. Seed yields were 7-9 bu/acre higher in early-seeded plots than in late-seeded plots. Seed lots with low conductivity and high germination in the standard germination test (SGT) and pre-chill test (PCT) had the best stand establishment. Seed lots with 1000-seed weights above 5.0 g had the highest shoot weights. Seed lots with a vigour index above 5.0 in the SGT or PCT usually had the highest shoot biomass and highest seed yield.
