Abstract
The depth of seeding study was conducted with Hy-320, Hy-355 , Line-912 and Neepawa wheats sown at depths of 2.5, 5.0, 7. 5, and 10.0 cm. Depth of seeding significantly affected all variables measured except bushel weight. There were no variety × depth interactions indicating that all varieties reacted the same to seeding depth. In general deeper seeding delayed emergence and maturity and reduced the number of plants. Maximum plant stand in the presence of triallate occurred at the 5.0 cm. depth with triallate-applied pre-emergent incorporated. When applied pre-plant incorporated, the presence of triallate reduced plant stands as seeding depth increased. There was no differential varietal responses to triallate.
