Higher yields require increased monitoring and correct management practices to avoid yield penalties... nitrogen supply at sowing should be 100-120kg n/ha, including the amount already in the soil and amount to be applied... Trial results have shown a narrower row spacing, such as 17.5 centimetres (above), can give higher yields in irrigated wheat than wider row spacings...

HRZ growers urged to be prepared for STB threat.. Mr Poole says rusts are a "puppy" compared to STB because fungicides do not achieve the same level of control as seen with stripe rust in Australia, and because the disease has a longer latent period which makes it more difficult to determine its progress... With the STB pathogen becoming resistant to strobilurins and triazoles in other parts of world and with evidence that the pathogen in southern Australia has some of the early stage resistance mutations to triazoles, Mr Poole is urging growers to use an IDM strategy and not base control on fungicides alone...

"In looking at fungicide options, bear in mind the recent discovery by Dr Andrew Milgate at New South Wales Department of Primary Industries of strains of the disease that show mutations conferring reduced sensitivity (low level resistance) to a number of triazole fungicides," Mr Poole said...

Matt Curtis in a paddock he sowed to Wedgetail in January 2015 to try and get some cover on a sand hill... Matt first sowed Wedgetail in March 2011 on the back of 500 millimetres of summer rain - an extraordinary event - and some encouragement from Mallee Sustainable Farming agronomist Michael Moodie... Matt has already sown about 20ha Wedgetail this year to cover up a sand hill, but he will terminate it in autumn and sow the paddock to vetch...

Slow maturing wheat yields solution to changing climate.. The research project monitored four wheat varieties planted across trial sites at Lake Bolac and Westmere (Vic) in the high rainfall zone, Temora and Junee (NSW) in the medium rainfall zone, and Condoblin (NSW) in the low rainfall zone, with each variety planted between mid-April and late May... Although dry conditions late in winter at Condoblin meant all varieties sown mid-April to mid-May had roughly the same yields, low density plantings benefitted the yield of slow maturing varieties Eaglehawk and Bolac , but reduced yield in fast maturing wheats sown later...

LIFTING YIELDS FROM 5T/HA TO 8T/HA OR MORE Growing irrigated wheat in southern New South Wales and northern Victoria is more than simply adding water to dryland varieties... Higher yields require increased monitoring and correct management practices to avoid yield penalties... Constraints to achieving 8t/ha include late sowing, poor tillering, low water allocations that prevent the correct number of spring irrigations, inadequate nutrition, lodging, lower wheat prices or other agronomic factors...
