Take home messages • Match optimal flowering period to growing environment to maximise grain yield potential. • One variety doesn’t fit all; there are no commercially available varieties that are broadly adapted across a wide range of sowing times or growing environments. • Optimising variety phenology and sowing time combinations achieves grain y...
-
Take home messages: Dry conditions severely limited grain yield for both chickpea and lentil in 2019.Results from 2018 and 2019 indicate that sowing around the mid-May period gave the varieties tested the best opportunity to avoid abiotic stresses and allows efficient conversion of biomass to grain yield. Earlier sowing resulted in greater biomass ...

Take home messages • Sustainable intensification is based on simultaneous improvements in productivity and ecosystem health to underpin profitability. • It is not more of what we are currently doing; it requires significant system changes towards greater diversification involving crops, forages, livestock, shrubs and trees. • Regeneration of soil h...
-
Take home messages • Direct placement of prilled lime below the seed row can be used to effectively ameliorate subsurface soil acidity, however the amelioration is limited to the sowing row. • Soil sampling at 0-10cm is insufficient at identifying soil pH stratification, finer sampling increments of 5cm should be used....
-
Take home messages • Crop yield is a primary function of grain number per unit area; grain weight is secondary. • Grain number is defined in a crop-specific critical period. The most critical stage is shortly before flowering in cereals, and shortly after flowering in pulses and canola. • There are two distinct effects of elevated temperature. Firs...
-
Take home messages • The pool of publicly available off-farm data that may be relevant to combine with on-farm data is increasing and can now be swiftly gathered for any farm or field. Collecting and using this data to make more informed decisions is an opportunity for growers. • Machine learning and hybrid models derived from large data sets and f...
-
Take home messages • Crop legacy effects outlined in this paper relate to two consecutive dry seasons (2018 and 2019). • Earnings before interest and tax (EBIT) in 2019 was highly correlated with the conversion efficiency of water to product (kg/ha/mm) and this was affected by crop species, sowing time and nitrogen management over both the 2018 and...
-
Take home messages • Oaten hay has the potential to be a higher return option than grain-only oat crops in seasons with spring drought conditions. • Oaten hay production for export markets requires increased agronomic management than domestic hay production or grain-only crops....
-
Take home messages All cereals (wheat, barley, oats) displayed the ability to recover from extreme frost events at stem elongation through re-tillering. Match phenology to sowing dates to begin flowering when the frost risk has passed is critical to yield formation. However, stem elongation exposure to frost is also important to yield develop...

Paper presented at the GRDC Grains Research Update in Wagga Wagga in February 2020 on the interaction of soil pH and sulfonylurea herbicide degradation on legume growth, presented by Anne-Marie Farley....
