Varietal differences in yield loss with delayed harvest can be in excess of 1.5 t/ha... There was a large difference between the amount of height reduction measured at the two sites with the maximum height reduction being 7 cm at Spring Ridge in 2011 compared to 34 cm at Moree in 2012... The low protein of Commander has generally been an advantage to meet malt specifications over the past couple of seasons extremely low proteins have been achieved throughout the region (<9%) suggesting that yield may have been sacrificed at this level...

Modelling the risks involved with splitting N application at Bellata over a number of years.. Current best nitrogen management practice is generally to assess soil water and soil nitrogen levels before sowing, estimate yield potential and fertilise all prior to, or at, sowing because it is too risky to apply in-crop... There is a large decrease in frequency from one to two rainfall events, suggesting growers would need to be very organised and be able to respond in a short time frame to take advantage of incrop N application opportunities...

Saturating winter rain across parts of southern and central NSW have left some crops waterlogged and growers questioning how to approach nitrogen (N) management over the coming weeks... The challenge facing growers is to determine whether N should be applied to water-affected crops and if so, how much and when... Incitec Pivot Limited (IPL) technical agronomist Jim Laycock said N applications should only be considered in paddocks where water is laying when that water is receding and soil has begun to dry out...

There were limited yield responses to topdressing N in 2005 and 2006 (1/11 sites) Top-dressing resulted in increases in grain protein rather then grain yield indicating that N application needs to occur before the 8 leaf stage to maximise yield responses... The aim of the research was to determine whether in-crop N application is a useful practice in wheat and sorghum for farmers in the northern cropping zone... In contrast to grain yield, grain protein showed a more frequent increase with top-dressing indicating that N application may have occurred too late to contribute to yield...

Central Queensland grower Peter Mifsud grows sunflowers as a profitable break crop to help manage feathertop Rhodes grass on his property north-east of Clermont... Peter says sunflower cropping has become a "vital tool" in the past five years due to increased pressure from FTR grass in his mixed farming system north-east of Clermont... Although the Mifsuds primarily grow the oilseed crop for its weed-control benefits, Peter says sunflowers have been a lucrative addition to their enterprise mix, which includes sorghum, maize, chickpeas, wheat and cotton...
