HYC Barley G.E.M Trial Series - Time of Sowing 2_VIC locations
Aims

The 2023 G.E.M trial looked to investigate the agronomic and economic influence of four management approaches- ‘low’ input (minimalist approach), ‘high’ input (no expenses spared), ‘strategic’ input (tailored approach based on pre-season forecasts/expectations) and ‘tactical’ (tailored approach based on strategic with in-season adjustment guided by climate and in-season triggers) on 6 varieties

Key messages
  • The highest yielding treatment was with the quick developing Rosalind variety under strategic input (8.03t/ha) which compared to other managements received a lower amount of nitrogen (150kg N/ha) but relative robust fungicide and PGR management.
  • There was a significant interaction between variety and management with Neo being consistently the highest yielding variety with no difference in yield across the different managements, unlike Rosalind where management approach had a significant effect.
  • Pixel, a slow developing 6 row winter barley variety also yielded best under strategic management, however it preformed poorer than the other spring barley varieties suggesting that the later time of sowing was not appropriate for this variety.
  • RGT Planet and Laureate yielded best under the tactical management strategy and benefited from additional N (175kg N/ha) and robust PGR and fungicide inputs.
  • Net From Net Blotch was the dominant disease in this trial with lower levels of Spot Form Net Blotch (SFNB) and Scald also being found.
  • Rosalind, Laureate, Pixel and Fandaga displayed strong disease resistance, showing low levels of NFNB (<6% plot infected) and no disease differences in response to changing fungicide inputs.
  • Neo showed low to moderate levels of NFNB infection and gave statistically significant decreases in infection with the higher fungicide inputs in ‘High’ and ‘Strategic’ managements. RGT Planet showed the highest level of disease with 81.3% plot infection when left untreated with fungicide. It required the highest level of fungicide input to significantly reduce infection from the levels recorded in the untreated however NFNB levels still remained above 70% of plot leaf area infected.
  • Driven by high proteins, no treatment was able to meet malt standards for barley.
  • With the lack of improvement in quality and little yield change in response to agronomic inputs, the ‘High” management approach was the least profitable scenario in 5 out of 6 varieties under a partial (based on variable inputs and applications only) gross margin analysis.
  • For Rosalind, Laureate, Pixel and Fandaga, the more tailored ‘Strategic’ or ‘Tactical’ managements were most profitable. In contrast the costs of management and resulting income in Neo and RGT Planet could not be offset which saw the ‘Low’ management option becoming the most profitable
