Crop diversity lifts profitability.. Pastures, pulses and oilseed crops not only provide solutions for disease, weed and nitrogen issues in cereal programs - they can also boost your bottom line... This 'break-crop effect' often extends to the second wheat crop (but rarely to a third except under dry conditions), reinforcing the need to consider the economics of break crops across the whole sequence, not in a single year...

Dry weight response of crops to increasing P levels with and without mycorrhizal fungi in the soil... Unlike saprobic soil fungi, which colonise and break down organic matter and do not require a host plant in the system to complete their lifecycle, arbuscular mycorrhizal fungi (AMF), the type found in cropping systems, do require the presence of a host to reproduce and are called obligate symbionts... Having adequate populations of mycorrhizal fungi present in soils can be beneficial and in some cases essential for crop growth...

Growers have moved in and out of raised beds as the seasons have varied... SFS CEO Jon Midwood, who leads 10 full-time staff in the 18-year-old organisation, suggests one solution to achieving consistently high yields from 500 to 1000 millimetres of rainfall in a varying climate could be "making the bucket bigger"... The bigger bucket would work by buffering the moisture available to the crop, rather than swinging from dry to overflowing or waterlogged, particularly in the more sodic subsoils in the winter...

"Reports commissioned by the Grains Research and Development Corporation (GRDC) have found that losses would be much higher without the disease control measures used by growers," GRDC plant health senior manager Rohan Rainbow said... "The reports show that one single disease - blackleg in canola - has the potential to cause national losses of $331 million - but the actual cost is much reduced at $77 million by using current controls.".. Dr Rainbow said the figures in the reports reflected the achievements made in researching, developing and implementing disease controls in the Australian pulse and oilseed industries...

Minor grains industries suffer from a lack of access to sufficient pesticide based pest management solutions... It is important that positive steps be taken to improve the number of pest management options available to growers of minor crops... The primary output of the project are Australian Pesticides and Veterinary Medicines Authority (APVMA) minor use permits allowing access to an increased number of approved insecticide, fungicide and herbicide options available to growers of minor grains and oilseed crops...

Collaboration with ICARDA, the International Center for Agricultural Research in the Dry Areas, will be stepped up following a recent GRDC trip to its headquarters in Aleppo, Syria... The visit involved meetings and laboratory and field visits with scientists involved in genetic resource conservation, breeding, biotechnology, integrated pest management (IPM), agronomy, water-use efficiency, marketing, seed production and crop/livestock integration... The work being done at ICARDA and the similarities between the southern Australian and northern Syrian environments - including dry summers and drought, pests and diseases, weeds, soil management and rotations - impressed the GRDC team...

The GRDC reports by Gordon M Murray and John P Brennan also state that breeding programs for Ascochyta blight management in chickpeas are preventing potential additional losses of $15.7m annually, while cultural practices and fungicides save the industry $6.9m and $12.4m respectively in Ascochyta losses each year... The current loss from diseases in oilseeds averages $137 million per year, or 27.6 per cent of the gross value of oilseed production, while pulse diseases are responsible for annual losses averaging $74 million per year, or 14.8 per cent of the gross value of Australian pulse production... Production losses due to diseases caused by fungi, nematodes, bacteria, viruses and phytoplasmas would be far higher without current controls such as the use of resistant varieties, crop rotation, paddock management and the use of pesticides, according to the reports...
