Project Code: CARP 2004-14.6

Final Report: December 2007

Summary: The first objective of this study was to investigate the effect of production practices on the quality and vigour of open-pollinated Argentine canola. Seeding date and swathing time of the mother crop had a significant effect on seed quality. Seed lots from plots that were seeded in early May and swathed when the moisture content was less than 20% had the fewest green seeds, lowest conductivity, highest seed weight, highest germination and highest vigour index. The seed lots were grown at multiple locations to determine the effect of seed quality on the performance of the seed lots in conventional tillage (CT), minimum tillage (MT) and zero tillage (ZT). Seed lots with conductivity below 75 (micro)S/cm/g, 1000-seed weight above 2.8 g, germination above 95% and vigour index above 2.8 had the best stand establishment, highest shoot weight, highest biomass and highest seed yield.
