Impact of sowing time on crown rot in barley, bread and durum wheat – Walgett 2012

Abstract

Key findings • In durum, low plant populations coupled with an early sowing time halved the yield loss to crown rot (12%) compared to a later sowing time with a higher plant population (25% yield loss to crown rot). • A full profile of soil water at the start of the 2012 season at the trial site limited the yield losses from crown rot in durum to 15–30%, while losses were 7–15% for bread wheat and minimal for barley (<5%). • Variety selection had a significant impact on yield in the presence of crown rot infection in each of the winter cereal types (up to 1.4 t/ ha in durum, 0.8 t/ha in bread wheat and 0.7 t/ha in barley).
