The project has shown how the practice of SSM can deliver large, consistent and recurring increases in the yields of cereals, canola and pulse crops grown on Sodosol soils across the HRZ of Victoria... The practice was developed to overcome crop yield constraints caused by dense clay subsoils that are widespread across the HRZ. Low aeration in the clay limits deep root growth into the subsoil and this has been identified as a cause for the generally disappointing crop yields in the Victorian HRZ. Earlier research demonstrated how SSM can transform the physical properties of the clay layers... For sites with the 1/2 SSM treatment (6 site x seasons), the commercial wheat crop yielded an average of 6.2t/ha, the full SSM 9.7t/ha, and the 1/2 SSM 8.8 t/ha (42% response).This was surprising and suggests that this lower rate of manure incorporation will also give increases in grain yield...

The database underlying the BFDC Interrogator contains the results of more than 5000 soil test calibration experiments conducted in Australia since the 1950s... Soil test-crop response (N, P, K and S fertiliser) trials have been undertaken by many different organisations in Australia since the late 1950's... There have been a number of scientific publications (Crop & Pasture Science Special Issue, Volume 64) derived from the trial data contained within the BFDC dataset...

Adapting our current practices and varieties to focus on managing the three key phases of crown rot (survival, infection and yield loss) will determine the impact this disease has on your crops in the future... Yield achievement in the presence of crown rot (Figure 2) is perhaps a more useful means of comparing varieties rather than the extent of yield loss associated with infection (Figure 1) as a variety with the smallest yield loss may not always be the highest yield achiever... The agronomy of durum production has not been extensively evaluated in such a western environment due to limited commercial production in the region primarily based around concerns over the high susceptibility of this crop to crown rot...

Take home message Crystal A mungbean is a new variety of large, green-seeded mungbean broadly adapted to all mungbean production areas, and the most complete package of yield, quality and agronomy currently available to Australian mungbean growers Resistance to powdery mildew and tan spot has been identified in new germplasm Now developing and evaluating the next generation of mungbean varieties.. The National Mungbean Improvement Program was initiated in 2003 to develop and release new varieties with increased productivity and restore grower confidence in mungbean as a reliable summer cropping option... New lines that combine the yield and agronomic characteristics of current varieties with disease resistance will form the next generation of mungbean varieties...

GRDC Grains Research Update Goondiwindi, March 2014 as yields increase, i.e. the bug threshold for a 4t/ha soybean crop is twice that for a 2t/ha crop (Fig. 2), and similarly for mungbeans - see comparison between 1t/ha and 2t/ha crops (Fig. 3)... In summary, action thresholds for edible soybeans and mungbeans are set for bug populations predicted to damage 2% and 1.4% of seeds respectively...
