• Highest yields for winter wheats come from early to late April establishment. • Highest yields of winter wheats sown early are similar to Scepter sown in its optimal window. • Slower developing spring varieties are not suited to pre-April 20 sowing. • Different winter wheats are required for different environments. • Flowering time cannot be ma...

• Barley is capable of maintaining a yield advantage over wheat in southern NSW across yield environments. • New barley varieties such as RGT Planet and Banks offer alternative phenology patterns compared to the benchmark fast spring type La Trobe. • In southern NSW, most spring barley types are still suited to traditional May sowing dates, and ear...

• Phosphorus (P) stratification can impact on the critical P requirements of grain crops. In northern NSW and Queensland placing P at 20cm below the soil surface resulted in significant grain yield responses (~13% increase in wheat) (Bell et al., 2016). These findings are worth further consideration in other regions of the Australian grain belt par...

• Fertiliser savings after drought or failed crop are possible with phosphorus (P) where there has been an extensive P fertiliser history and Colwell P values are at or above crop critical requirements. As a guide, one third of average crop P replacement can be applied down to a base level of 3-4kg P/ha. • Savings in nitrogen (N) are likely to be ...

• The early results of this project showed great potential in improving soil structure and crop productivity in sodic subsoils using deep placement of organic and inorganic amendments. The increases resulted from improvement in the physical and chemical properties of the clay soil volume around the rip line containing the organic and inorganic amen...

• Safflower is a winter/spring growing crop that is: o heat and drought tolerant, o moderately tolerant of sodic and saline soils, o suited to both dryland and irrigation farming systems, o low input, low maintenance and easy to grow, and; o has machinery requirements similar to cereal /canola production. • Super high oleic safflower has been devel...
