To investigate the fit of high value pulse crops (faba bean, lentil, and chickpea) in the sowing program and their rotational (agronomic and economic) benefits to the following cereal crop.
Faba bean sown in 2019 significantly reduced Pratylenchus neglectus (root lesion nematode) numbers. Lentil and canola also reduced P. neglectus but to a lesser extent. This carried through to 2020 sown wheat where populations remained low.
In 2019, faba bean was the lowest risk non-cereal option in the break crop phase to manage a late start or dry finish, although wheat outperformed all crop types in terms of yield and gross margin in 2019.
Wheat sown in 2020 yielded more when sown after pulses (faba bean, lentil, chickpea) compared to when sown after canola or wheat,
In a poor season or low rainfall situation the low nitrogen strategy (30N basal) offered the best returns, there was no yield response to higher rates of nitrogen applied in-season.
Wheat after pulses had the greatest yield response to applied nitrogen.
Protein response to nitrogen rate was higher in wheat-wheat compared to when sown after break crops.

TerminologyOnline Farm Trials: a web-based information system that provides open and free access to agricultural-based research trial data and information. OFT is a digital online resource managed through a collaboration between the Grains Research and Development Corporation (GRDC) and the Centre for eResearch and Digital Innovation (CeRDI) at Federation University Australia (FedUni).
Trial Contributor: an individual or organisation (e.g. grower group, research centre, commercial entity or government department) that makes data and/or other information available through OFT.
Metadata: information about Trial Projects submitted to OFT (e.g. names of the Trial Contributors, Trial Project title, Trial site location, Crop type(s), Growing season year(s), Trial type and Trial design). This data is compiled by OFT from information submitted with Trial Projects.
