Rotate barley crops with non-hosts such as wheat (to control foliar pathogens), legumes or summer crops; avoid sowing barley on barley and maintain clean fallows... The main foliar diseases of barley are leaf spots, rusts and powdery mildew... Barley is tolerant to root-lesion nematode infection and is a good winter cropping option in infested areas...

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fallow following sorghum, and just 13% were double cropped into wheat or barley stubble (L Serafin and S Belfield, unpublished)...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...

Sunflowers build a little profit bridge over the summer.. The Zwars took advantage of 100 millimetres of rain in early November and sowed a mix of millet, sunflowers and cowpea on 80ha of hay stubble in a paddock prone to waterlogging... Russell would like to see further research into the role of cover crops in southern farming systems: "It's hard to put a number on what the benefit is from the diversity in our system - I'd be interested to see how the numbers stack up over a 10-year period...

Improving water use efficiency using cover crops of millet... Soil water was measured at cover-crop planting, time of spray-out (2004 replicated sites and all 2005 sites) and at all sites at winter crop planting... In the analysis an average world oil price of US$68.40 a barrel (West Texas Intermediate) and an exchange rate of US74 cents is assumed...

Recent trials have shown that spring sowing of winter canola can provide increased returns compared to a summer fallow... Spring-sown winter canola at Dunkeld pictured just before grazing in summer 2011 (left) and at flowering in spring 2012 (right).. For a winter variety, this means plants can be sown in spring, grazed during summer and then grow and recover in the lead-up to winter...
