Australian Wheat Demonstration Series
|
The purpose of these trials was to demonstrate to growers how the various varieties perform in terms
of actual financial returns, not just yield.
|
Grainco Australia Seeds |
Wheat Variety Evaluation
|
The trials were conducted to evaluate new genetic material in the field. Selections are made and these
are subsequently re-tested.

Chickpea Response to Row Space and Plant Population in the
Western Downs/Maranoa
|
There was uncertainty about the optimum plant population and chickpea response to wide rows compared to
narrow rows.

Chickpea Variety Comparisons in the Western Downs/Maranoa |
New varieties becoming available need to be assessed for sustainability in Qld's western farming areas.

Frost Risk in Canola
|
Experiences with canola in the northern region in the late 1980s and early 1990s suggested that, with the
then current cultivars and early-season sowing, the risk of yield damaging frosts was high.

|
Seasonal Variation in Canola Productivity
|
Canola is a relatively new crop to the northern grains region and experience is limited on yield expectations
and seasonal variation in yield and oil content, both of which determine profitability.

Faba Beans in the Western Downs/Maranoa
|
Faba bean may be a suitable rotation crop to wheat in the region and information on yield potential is needed.

Mungbean Variety Comparisons in the Western Downs/Maranoa
|
Mungbeans are a new crop in the region and information on local variety performance is required.

Comparison of Winter Crop Rotations – ‘Dunkerry
South’ Trial, Nindigully

Crop and Pasture Rotations for Red Earth Soil – ‘Mulga View’ Trial, St George |
Because of the inherently low soil fertility and water holding capacity of many of the red soil types in the
Balonne and Maranoa regions, different farming systems may be needed for their sustainable development.

The Effect of Row
Configuration on Yield and Water Use in Grain Sorghum |
At potential grain sorghum yield levels below about 2.6 t/ha, skip-row configurations produce the same or
higher yields than solid plant configurations. |

the subtropics of southern inland Qld.

Killing Lucerne in the Western Downs/Maranoa – A Real Challenge |
Lucerne is difficult to remove using zero till methods. Further assessment of chemicals and chemical
combinations was warranted.
|
John Lehane |
Lucerne for the Western Downs and Maranoa |
Due to the structural stability and inherent fertility of the cracking clay soils used for cropping in the
Qld grain belt, the culture of farming in this region is based on a cropping monoculture, that has caused
severe fertility degradation.

Caatinga Stylos: A Promising Legume for Lighter Textured Soils |
The stylos are well known as summer growing legumes for poorer soils of northern Australia. In the past they
have found it difficult to perform consistently in the colder areas of Qld.

New Pasture Legumes Sown in Regional
Trials in Queensland |

Controlling Crown Rot – an important disease in the
Western Downs |
Crown rot is carried over from one crop to the next as fungal threads, in the residues of diseased winter
cereals or infected grass residues.

Pink wheat checked by specialists |
There seems no evidence that pink-coloured wheat grain caused by the disease yellow spot can
adversely affect livestock.

Avoiding Costly Herbicide Resistance in Weeds

Farmers who have been using herbicides from the same chemical group for three or more years may have developed
herbicide resistence on their properties.

Soil Characterisation in the Balonne Shire through
Farmer-Scientist Collaboration
|
Management of soil moisture is one of the most critical factors in the cropping systems of the Balonne Shire.

Is it Necessary to Fallow Red Loam Soils From Harvest?
|
Is it worthwhile beginning fallow operations in November, after harvest, on red soils?

Brett Robinson |
Comparisons of Conventional and Zero Tillage, 1996-1999 |
Does zero tillage result in the benefits of soil water storage and grain yield that have been found in other
regions?
|
Greg Thomas |
Soil Characteristics and Crop Water Use on a Red Sodosol |
Sub-soil characteristics including salinity, sodicity and high bulk densities of many soils in the region
limit water extraction and nutrient uptake.

Sustainability Indicators |
Indicators are things we can measure or estimate quickly, that will help us make decisions and demonstrate
that our practices are sound, both financially and environmentally

Sustainability and profit |
Systems that make the make the best use of water are most likely to be more profitable and sustainable,
especially in a water-limited environment.

Improving plant available water at sowing |
Water storage can be improved through longer fallow, no weeds, high soil cover, less tillage, and attention
to soil water status

Deep Drainage Under Clay Soils: The Role of Fallows
|
Fallowing plays an important role in Australia's dryland cropping systems.

Benefits of Long Fallow on Grey Clay Soils |
Long fallow between wheat crops can lead to yield and protein increases, as well as reducing disease
between cereal crops |
Nick Christodoulou |
The Effect of Cropping Systems on Deep Drainage
|
Increasing cropping frequency, opportunity cropping, using more summer crops and including perennial pastures
in a crop rotation can reduce deep drainage and make more money at the same time

Soils with Sub-soil Constraints

What is the value of moisture-seeking for winter
crops in the marginal cropping zone of south-western Queensland
|
Moisture-seeking appears to be a highly effective means of achieving higher yields in wheat crops.
Increases in yield per hectare per year of more than 20% are possible. |

Targeting Yield and Protein
|
In many subtropical environments, cereal crops develop and mature largely on residual water in the soil.
This research evaluates the impact of plant available N and water in the soil on grain protein.

N and P Nutrition at Talwood |
Due to the relatively young age of cultivation in the area and the high inherent nitrogen fertility of the
soils, responses to applied N fertilisers in cereal crops have been inconsistent.

Wheat Responses to Nitrogen Fertiliser – an economic update
|
The economics of nitrogen fertilizers have changed. The practice of applying urea fertiliser to wheat crops
to increase yields and wheat protein content has become well established.

Yield and Protein Benefits of N Fertilisers for Wheat on
Red Loam
|
Yield and protein increases due to N fertilisers are less certain in the western region due to low and
variable rainfall.
