This one-year investment aimed to provide growers and advisers along the South Coast of WA with greater confidence to make decisions on whether to sow a cereal crop later in the growing season (late winter, early spring) after crop failure, or inability to seed, due to early season waterlogging. It also aimed to provide some data on what varieties and nitrogen fertiliser strategies might be required for later sown crops.
The trials implemented demonstrated that crops can be successfully established in late winter and early spring when conditions are favourable, with barley yields as high as 7 t/ha harvested at the Munglinup trial site with a late-August sowing date. The trial data also showed that main season and shorter season varieties, for the most part, yielded similar to each other. Results relating to nitrogen treatments were variable, most likely due to the ‘all up front’ application and the leaching that occurred due to above-average rainfall received.
Four small plot trials, with similar treatments and trial designs, were implemented along the South Coast of WA in 2022. Two of these were located in the Albany Port Zone (Green Range and Needilup) and two in the Esperance Port Zone (Munglinup and Condingup). Each trial site included:
Three times of sowing (late August, mid-September, Late-September)
Two wheat (Vixen and Scepter) and three barley varieties (Maximus, Planet and Rosalind)
Two nitrogen treatments (High - 80 units of nitrogen, Low - 40 units of nitrogen)
The trials sown by experienced trial providers and were monitored throughout the growing season. Measurements for each treatment across each time of sowing included:
Plant establishment (plants/m2)
Growth stages
Harvest yield (t/ha)
Grain protein (%)
The trials were each sown in three ‘time of sowing’ blocks with 12 randomised wheat treatments and 18 randomised barley treatments. This totalled 90 small plots at each site.

Plant Breeders’ Rights (PBR)
Some crop varieties used in research trials may be covered by Plant Breeders' Rights (PBR). Users should confirm PBR status of relevant varieties by searching the IP Australia PBR database, http://pericles.ipaustralia.gov.au/pbr_db/ or Variety Central (http://varietycentral.com.au/) and contacting variety owners for further information if required. Where possible, varieties have been listed according to their registered PBR name, although OFT cannot and does not guarantee that the information is accurate or complete.
Note that PBR cover is administered through the Plant Breeders’ Right Act 1994 (
