HYC Barley G.E.M Trial Series - Time of Sowing 1_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
  • There was no interaction between variety and management with all varieties responding similarly. Low input, which was characterised by cheaper fungicides, no PGR and less applied nitrogen, yielding significantly less than the other management approaches (Table 1).
  • On average the quick developing but adaptable variety Rosalind yielded best (7.19 t/ha) with the slower developing spring barley Laureate also preforming strongly (6.98 t/ha) (Figure 1).
  • RGT Planet and Neo suffered from high Net Form Net Blotch infection with untreated plots recording 98% and 55% of plot infected respectively. Robust fungicide in strategic and high input managements significantly reduced disease levels to less than 10% of plot infected in Neo. While still reducing infection in RGT Planet, NFNB infection was still between 88% and 94% plot severity (Figure 2).
  • High grain protein results meant no treatment achieved malting grade (Table 3).
  • Although there was no interaction between variety and management, economic differences have been observed when completing a partial net margin analysis. Varieties that showed very little yield differences between management, such as Pixel, meant reducing total operational costs under ‘low input’ was most economical (Table 7).
  • There was a yield trend in Neo and RGT Planet to yield less where less fungicide input had been implemented and higher disease was found. Therefore, the economic analysis shows that the additional expenditure in the ‘High’ input was justified. An additional margin of $160/ha in Neo and $581/ha in RGT Planet was made by shifting from ‘Low’ to ‘High’ input.
