2024 Pea Harvest Results

Posted on November 29, 2024

Our McCain Foods peas were harvested on the 26th of November, one week ahead of schedule. The dry spring meant the peas were ready sooner than expected. You can read more about this year’s pea season here.

Ahead of the machine harvest, in each plot we hand harvested all of the pea vines from four 2 x 1m2 subplots. The plants were taken to the McCains mini-viner in Waipawa where the peas were separated from the pods and the vine, and weighed to determine yield.

A subsample of the peas was used to determine the Tenderness Rating (TR). TR is a key factor in determining the price paid for process peas. Generally, a higher price is paid for lower TR peas, as the yield is typically lower. Subsamples were also collected for laboratory analysis, and for drying to determine dry matter content.

Some results!

We are still processing samples and awaiting laboratory results, however we can share the following.

Our Conventional treatment on average produced a paid weight of 5.74 T/ha, and the Hybrid treatment 4.69 T/ha. This is not unsurprising considering the slow start the peas in the Hybrid treatment had (see previous post).

The average Tenderness Rating (TR) for the Conventional treatment was 104, and the Hybrid slightly lower at 96. This means that the Hybrid yielded a higher price per ton than the Conventional.

At this stage, the estimate of income received from the peas is approximately $4290.20 for the Conventional treatment and $3797.50 for the Hybrid. We are still finalising input costs, and will report on margins later in the year. The Hybrid treatment did have a lower cost of production than the Conventional, so it will be interesting to see final gross margins.

Next Steps

We are due to plant our beans on the 28th of December. We have completed our post-harvest operations, which has included baling the vine on the Conventional treatment followed by disc ripping. The Hybrid was disc ripped to incorporate the vine, with the aim of retaining nutrients, particularly nitrogen. The Regen treatment was also disc ripped to mechanically kill the oats which had regrown.

The aim of disc ripping is to attend to any compaction, bury any residues, and level the surface as much as possible ahead of planting beans.

A big thanks!

As always, we want to thank our dedicated operations advisory team for their input into our pea crop.

This includes Mike Flynn, Ben Prebble, Allan Machakaire, Scott Marillier and Renee (McCain Foods), Bruce Mackay (Kraft-Heinz Wattie’s), Gareth Holder (Redloh), Scott Lawson (True Earth), Phil Schofield (Reset Regenerate), Shelley Bath (Horticentre) and Mike Kettle (Mike Kettle Contracting). We would also like to thank Jonny Wilson for completing the disc ripping, and navigating our small plots with very long equipment!
