This proposal is focussed on reducing the gap between current and potential yield in the high rainfall zone. Activity will be targeted at wheat and canola.

The HRZ has high crop yield potential however, current yield gaps are averaging at least 1 t/ha for wheat and 0.5 t/ha for canola in decile 2-5 years with an estimated 1-3 t/ha for wheat and 0.5-1.5 t/ha for canola in decile 8 years (Zhang et. al. 2006)

A key driver of the yield gap identified in a review by Robertson et al. (2016) is timeliness of application of inputs and operational logistics (e.g. sowing, weed and disease control, crop flowering and nitrogen application). The top 25% of growers have learnt and adopted timely practices in the HRZ (PlanFarm Bankwest 2016-17) and there is strong evidence that by assisting those not in the top 25% to adopt these practices will close the yield gap (Robertson et. al. 2016). Understanding the reasons for these differences in grower behaviour will take into account the socio-managerial drivers, whole-farm logistics and their appetite for risk and impact on profitability.

A proposed rD&E component of the HRZ investment (PROC-9175783) includes a grower baseline and end-of-project farming systems practice survey, paddock-scale demonstration trials that compare local district practice with a common set of system modifications (as informed by the small plot trials) and field days that include visits to both the paddock-scale demonstration sites and corresponding small plot trials.  An overall participatory approach is proposed, including growers, researchers and advisers to increase the rate of adoption of the research findings and to inform the R&D activity.

The proposed investment aims to have similar activity running in three port zones (Kwinana West, Albany and Esperance) concurrently.  Applicants may choose to apply to deliver the outputs listed below for one or more port zones.
