SUM19-02: N x P +/- K in Scepter Wheat, Esperance
Aim
To evaluate local wheat response to nitrogen (N), phosphorus (P) and potassium (K) fertilizer application.
Trial Details
Location: Hill Plains Farm, Mount Ney, Esperance region.
Trial Size: 44 treatments x 3 replicates = 132 plots.
Soil Type: Loamy sand over loam with carbonaceous rock inclusions.
Crop Sown: Scepter Wheat, 90 kg/ha, 30/04/2019.
Results
Key Notes
- Mount Ney experienced a decile 4 growing season rainfall in 2019. Nearby Beaumont fell 77mm below the 30-year average for the growing season, punctuated by very dry July and September months.
- Applying P and N increased yields but K was ineffective at the site.
- Establishment P rate has a strong influence on the ability of a crop to respond to in-season nitrogen application. Inadequate P = decreased N use efficiency.
- Under the 2019 seasonal conditions, applying P at 24 kg/ha and N at 100 - 120 kg/ha represented the best strategy to optimise profit from Scepter wheat.
