Pulse School: Scoring pulse nodulation success

The pea crop may not be a perfect 10, but that’s because its actually aiming for 13. What’s that now?

Nodulation is key to pulse crops’ biggest super power: nitrogen fixation. But nodulation doesn’t always go as planned, and assessing a crop’s nodulation score can help determine yield potential and highlight where inoculation management may need tweaked for next year.

In this Pulse School episode, Jenn Walker with the Alberta Pulse Growers explains how nodulation is scored out of 13, and includes assessing the overall crop health, nodulation placement, and number of nodules.

An assessment is best done just before first flower, so the video below is filmed slightly ahead of optimal timing, but Walker explains that simply means coming back a week later to compare if nodulation has improved over the week.
