• Intensive monitoring of soils and crops over a rotation sequence has identified why crops do not achieve their potential yield. • Reviewing paddock performance at the end of the season and using paddock records are essential for sustained improvement in agronomic performance. • Over the four-year rotation, 120 paddock zones were intensively monit...

• 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...

• Ensure flowering date is matched to the environment and grow enough biomass for the targeted grain yield. • High biomass was necessary for a high yield potential. There is no advantage in utilising management strategies that reduce growth in order to increase harvest index and grain yield. • Select two or three varieties with differing phenology ...

• 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 ...

Riverine Plains Inc conducts a range of research activities to provide local information to its members. • Large farm scale trials provide farmer-relevant information. • Understanding in-paddock variability can refine input use....
