Western Australian Barley Management Trials: Nitrogen, Density and Phenology Experiments (2012–2019)
Abstract
The collection datasets were from the project “The management of barley and barley cultivars in Western Australia (DAW00224)”. A total of 169 small-plot research trials and 17 phenology trials were sown during 2012-2019. The trials were conducted on a variety of treatments, including nitrogen rate, nitrogen timing, plant density, plant growth regulator treatments, foliar fungicide programs, and sowing date. The variables collected included grain yield, plant height, lodging score, awn emergence date, grain quality, grain protein, grain plumpness, hectolitre weight, screenings, grain brightness and grain hardness.

Comments
The project “The management of barley and barley cultivars in Western Australia (DAW00224) was funded by GRDC and DPIRD with a cost ration 50:50. Research conducted in this study was in Kwinana, Albany and Esperance Port Zones of Western Australia (representing 95 per cent of the area sown to barley). The research components were: 1. Determine the influence of intensive management (plant growth regulator, fungicide, nitrogen rate, seeding rate) on achieving barley yields greater than 6 t/ha in higher rainfall areas 2. Identify optimal plant density and nitrogen supply combinations for malt barley varieties across rainfall gradients 3. Develop nitrogen timing strategies that increase grain protein concentration to 10.5-11.5% while maintaining yield, hectolitre weight and grain plumpness. 4. Quantify duration to awn emergence across multiple sowing dates for 30 barley varieties to support the maturity decision tool (Flower Power). Trials were conducted at the following locations according to the following rainfall zones of Western Australia. 1. Low Rainfall Zones: Cadoux, Grass Patch, Lake Grace, Merredin 2. Medium Rainfall Zones: Bolgart, Katanning, Kojonup, 3. High Rainfall Zones: Brookton, Kojonup-W, Gnowangerup, Wittenoom Hills, Yerecoin A total of 169 small plot research trials (with a total of 27,354 treated plots typically 10 m long x 1.54 m wide) and 17 phenology trials (with a total of 6,960 hill plots sown with ten seeds) were sown over the seven-year duration (2012-2019) of the project. The collection included datasets from the trials treatments on variety (malt & feed), nitrogen rate (10-240 kg N/ha), nitrogen timing (Z31, Z37, Z49, etc.), plant density (40–280 plants/m²), plant growth regulator treatments, foliar fungicide programs, and sowing date (late April–early July). The variables collected included grain yield (t/ha), plant height (cm), lodging score, awn emergence date, grain quality, grain protein (%), grain plumpness (%), hectolitre weight (kg/hL), screenings (%), grain brightness and grain hardness
