Hyper Yielding Cropsn Wheat G.E.M Trials - NSW

• Grain yields of RGT Waugh were consistently higher yielding than other varieties, however the results indicated that there was a significant interaction (p=0.003) between management approach and variety.
• RGT Waugh, a white winter wheat stood out as having good harvest biomass, low head numbers and relatively better harvest index, even though its phenology was relatively slow.
• The varieties that gave significantly greater yield responses to higher inputs (compared to the low input approach) were Scepter, Stockade and RGT Cesario, a result that coincided in with greater disease pressure.
• Gross income after crop inputs were taken into account and varied from approximately $300 to just over $500/ha depending on the variety tested.
• Growing Scepter with a higher input of N (additional 40N), PGR and four fungicide units (High Input approach) generated the highest gross income as result of a better bin grade and higher yields.
• Other varieties were in general more suited to lower input management approaches with a single flag leaf spray of Prosaro 150mL/ha, no PGR and 150kg N/ha generating the most profitable crops with AGTW005, Longford and RGT Waugh.
• Tactically cutting back on the level of later season fungicide input (reducing expenditure at flag leaf and removing the head wash fungicide) was generally a practical and cost-effective management adjustment for all the varieties during the season.
