Sowing date, sowing rate and row spacing effects were studied on 25 wheat and 3 triticale cultivars in 1983-85 at Griffith, New South Wales. Highest mean grain yield was 891 g/msuperscript 2. Av. yield reduction was 50 g/msuperscript 2 or 6% per 1-week delay in anthesis after 1 Oct., but varied between 2 and 23%, depending on the season. Lodging was a significant problem in all 3 years, with less lodging for later sowing dates, earlier maturity types or shorter stature.
