By Damian Jones, ICC Key messages: No treatment (previous stubble susceptibility, fungicide or variety resistance) had any effect on wheat yield. In most years Yellow Leaf Spot accounts for minimal yield losses. Yellow Leaf Spot, has become a widespread and … Continue reading
Can we reduce nitrogen inputs for wheat sown onto high-input crop stubbles and still achieve high yields?
By Heather Cosgriff (SFS) Key messages: Soil nitrogen availability was very high prior to sowing, 321.6kg/ha available Incorporating poppy stubble led to high potentially mineralisable nitrogen levels There was no yield or protein response to additional urea applications Trojan generally … Continue reading
By Paul Breust and Aaron Vague (SFS) Key messages: Crops can be established and grown in 6.6t/ha of retained stubble in the HRZ without compromising establishment Stubble retention in the HRZ requires careful systems based planning and attention to detail Seasonal conditions … Continue reading
By Grant Hollaway (Department of Economic Development) and Stuart McColl (BCG) Key messages: Yellow leaf spot reduced grain yield in susceptible wheat cultivars by eight per cent. When sowing into paddocks with yellow leaf spot infected wheat stubble, farmers should consider growing resistant cultivars in preference … Continue reading
By Mark McLean (Department of Economic Development) and Stuart McColl (BCG) Key messages: SFNB caused yield losses of 0.2-0.3t/ha in very susceptible barley varieties at Quambatook during 2014. SFNB increased screenings by up to seven per cent and reduced retention by up to 13 … Continue reading
