CN4173254 · Local growers report a yield ceiling in oats, unlike barley, suggesting a challenge in achieving higher grain yield. This may stem from higher biomass and a source-sink imbalance, making oats more vulnerable to environmental stress. Last season’s trials support this, showing excessive nitrogen reduced harvest index and grain weight, ultimately lowering yields—likely due to increased biomass and greater susceptibility to terminal drought.

CN4148413 · Local growers report a yield ceiling in oats, unlike barley, suggesting a challenge in achieving higher grain yield. This may stem from higher biomass and a source-sink imbalance, making oats more vulnerable to environmental stress. Last season’s trials support this, showing excessive nitrogen reduced harvest index and grain weight, ultimately lowering yields—likely due to increased biomass and greater susceptibility to terminal drought (data available on request). Further reinforcing this, trials showed significantly higher yields when oats were planted in late March instead of late April, suggesting early seeding helps mitigate drought effects. Overseas research also links vegetative indices (multispectral analysis) at panicle emergence and early grain fill to final yield, suggesting these indices could serve as a tool for identifying unrealized yield potential. By comparing up to 3 milling oats varieties that with difference in phenology and crop architecture this research will seek to address the following issues: * Maximise oat yield, quality and profit through efficient use of nitrogen. * Provide insights into the relationship between time of sowing, biomass growth, nitrogen application, and grain yield in oats. * Identify whether variety specific characteristics offer opportunities to overcome the yield ceiling. * Identify the risk (lack of photoperiod hold) or benefits (grain yield) with early seeding of varieties. * Use multispectral technology to improve decision-making tools for growers. * Contribute to sustainable oat production by addressing yield limitations associated with excessive vegetative growth, terminal drought, and over-fertilization. Trials are to be applied to farmer-sown strips of up to 3 milling oats varieties that with difference in phenology and crop architecture (4 randomized replicates within each block). A range of environments to capture N response & rainfall/terminal drought influence: 1. Low Rainfall (Lake Grace): 4N rates, 2 TOS, 3 varieties (96 plots) 2. Medium Rainfall (Narrogin): 4N rates, 2 TOS, 3 varieties (96 plots) 3. High Rainfall (Williams): 5N rates, 1 TOS, 3 varieties (60 plots)

What these values mean

Each amount is the reported full contract value, including GST where applicable, in nominal Australian dollars. It covers the reported contract period. It is not annual expenditure, cash paid, all government spending or spending in a supplier’s local area. Unexercised future options are not necessarily included.

This snapshot includes every notice in 82 consecutive weekly exports, covering 2 March 2025 to 26 September 2026, retrieved 1 October 2026 (UTC date). AusTender lists only about eighteen months of exports, so weeks before 23 March 2025 are kept from our earlier downloads. Each contract contributes its latest observed version once. Earlier versions remain available in its history; values of successive amendments are never added together. Date filters use that latest observation’s publication date, including amendments, not the contract start date.

Weekly files describe information at extraction. Later corrections, cancelled notices, or contracts with no publication in this archive may be absent. This is not the entire historical AusTender register. Some source timestamps fall just outside their file’s labelled week; their reported dates are retained. Three malformed observations have shifted columns; affected supplier/category fields are marked unavailable. Source dates in 1900 or end dates in the next century are flagged, not interpreted as ordinary durations.

Supplier grouping uses reported ABNs with a valid checksum; it is not independent verification against the business register. Missing or invalid ABNs remain separate by contract. Equal names do not establish equal legal entities. A contract award is not evidence of wrongdoing.
