In a survey of 134 paddocks across the northern grains region during 2003-06, we found that 41% of sunflower crops were sown into a long fallow following a winter cereal (wheat or barley), 25% of crops were sown into a short fallow following sorghum, and just 13% were double cropped into wheat or barley stubble (L Serafin and S Belfield, unpublished)... Further trial work is needed to provide additional data to develop our understanding of the full impacts of sulfur nutrition... The results suggest that sunflower oil contents may be more specifically targeted and fertiliser N inputs more accurately determined for optimum profitability...

Coleoptile length is an important characteristic to consider when planting a wheat crop, especially in drier seasons when sowing deep to reach soil moisture... The coleoptile lengths were measured on a range of varieties that are grown in Australia and have been evaluated as part of the National Variety Trials (NVT) program... The length of the coleoptile was measured after 14 days at 21o C. Individual seeds with a coleoptile length of less than 4 cm were not considered viable and were recorded as missing data...

Advice concerning the significance and control of the more common pests, or potential pests, of these crops is presented... Value of the crop (high value crops cannot sustain too much damage as a small loss in yield or quality could mean a large financial loss), the cost of the spray and its application and the likely yield or quality benefit gained from control... Crop monitoring Ongoing monitoring of crops and surrounding vegetation is essential to determine the presence of both pests and predators, and when, if any, intervention is required to keep pests at an acceptable level or, if feasible, boost predator numbers by introducing them into the system...

Until such varieties are released, northern growers and advisers need to select varieties firstly on the basis of crown rot risk and then manage for stripe rust ... There is a risk of WSMV being spread through infected seed into new areas... We have not been able to determine an economic threshold for RGB in sorghum from these trials...

Central Queensland farmers now have a new enemy in the battle against herbicide resistant weeds - glyphosate resistant Sweet Summer Grass... Mr Cook urged growers to check paddocks for survivors after spraying glyphosate and have them tested for resistance to ascertain what herbicides are still effective... "Effective control is likely to be a combination of other effective herbicide modes of action in combination with non-chemical tactics such as strategic cultivation, or if a small number of plants, hand roguing," Mr Cook said...

Mixed cropping farmers looking to maximise productivity from winter crops can consider grazing some grain only varieties of wheat, barley and triticale without sacrificing final grain yield... That's been the take home message from recent trial work funded by the Grains Research and Development Corporation (GRDC) and undertaken by the NSW Department of Primary Industries (NSW DPI) comparing the performance of dual purpose and grain only varieties in terms of dry matter production and grain yield... Management is critical though with the research confirming that variety selection as well as timing, intensity and number of grazings plays an important role in maintaining grain yield...
