A research project in the Great Southern region has demonstrated that the decision tool Yield Prophet could help local growers maximise crop yields and minimise risks associated with management decisions... "Following a number of extremely variable seasons, many growers in the region have lacked the confidence to implement management practices to maximise yields, and have been taking an approach of 'less risk' for their in-season decision making," Mr Whisson said... Mr Whisson said the benefit of Yield Prophet to local growers over the course of the season was obvious, especially when it came to making nitrogen and fungicide decisions based on forecast yield, as well as providing side benefits such as yield estimates for insurance purposes...

Vigorous plant growth and high water use efficiency make barley an excellent choice for double cropping from a summer crop back to a winter rotation... Fitzroy has good levels of resistance to net form of net blotch, but it is susceptible to powdery mildew, leaf rust and spot form of net blotch... Shepherd is resistance leaf rust and most net form of net blotch isolates, but it is susceptible to the spot form of net blotch and a new isolate of powdery mildew...

Eyes on the market as season unfolds.. We sowed our canola, oats and barley deep - 18 centimetres, with around 8cm of soil over the seed in the furrow - to chase moisture... As a first-time dry sower, we decided to sow barley, wheat and brown manure vetch, as we considered these to be lower risk in a false-break scenario, and they can still be managed with a staggered germination...

Overall, both models are acceptable for modelling soil evaporation over a range of soils and seasons provided accurate soil physical properties and starting water states are known... Overall, populations increased five times compared to before planting the summer crops, but remained below 250/kg soil (Figure 4)...

Influence of fungicide rate (mean of fungicide products - four site mean) Stem rust control assessed over the four trial sites revealed that using high rates was essential for the control of the disease, even if the fungicide had been applied prophylactically (before infection was visible in the crop)... Influence of cultivar resistance and fungicide application (Prosaro ) on yield and stem rust severity measured on the flag sheath 18 days after fungicide application at early dough (GS82) and assessed at mid dough - physiological maturity (GS85-90) - Bairnsdale, Gippsland, Victoria, 2010... The yield potential for the crop with no nitrogen applied is estimated at GS30 from the results of numerous of trials conducted in that region where NDVI at GS30 is divided by the number of growing degree days (GDD) greater than 0 C since planting, referred to as the INSEY units (in season estimate of yield)...

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...

The project was established to provide advice to breeders on how to improve the adaptability of crops in the high rainfall zone (HRZ) of southern Australia so that yields could be lifted closer to potential... Information from the project needs to be extended to growers to provide guidance as to the likely impacts of different management strategies on the germplasm currently available... 2. Better understand crop growth and development of existing germplasm in the HRZ Field experiments were conducted to provide information relating to how current commercial germplasm (wheat, barley, canola and pulses) captured resources and the efficiency with which these crops converted these resources to biomass and grain...

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... Growers need to protect the crop at head emergence and into flowering by pushing the first irrigation period forward, compared with when they would normally irrigate (see Figure 1 below)... 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...
