The Pea YEN was established in 2016 with support from PGRO and 15 commercial sponsors. Pea YEN has sought to understand the variation in combining pea yields between fields, farms and seasons, with a focus on measurements rather than competition. It is open to all interested parties, with all crops entered receiving a comprehensive report, detailing how their crop performed compared to other crops in the YEN.

The first six years of the Pea YEN have been supported by independent pea agronomist Keith Costello sharing his knowledge, taking in-season measures and samples to produce a practical protocol for growers and agronomists specific for peas.

All members will receive a comprehensive report, newsletters and are invited to discuss results, experiences and ideas at the Results Conference.

Corporate Sponsors support the network to maintain its core activities.  Their vital role is recognised in all YEN publicity, media items, conference presentations, and on this website.

Sponsors have a key role in steering the evolution of the network and its activities.  They have access to network information, intelligence and discussions to support their own yield enhancement initiatives.

Sponsors can also make multiple competition entries and have multiple attendance at the annual YEN conference. A few sponsors will also contribute some or all of individual farmers membership fees. For more information, please see the Pea YEN sponsorship enquiry page.
