Other trial notes

Seed size is critical to the marketability of lentil. In PBA HallmarkXT, there was some mixed price signals due to variability in seed size and it not quite fitting into one of the 3 market classes (small, medium & large); this has has stabilised over the 21 harvest and no price discounts are apparent. In 2020 & 21, we sourced seed from the previous season and graded it into seed size categories from >5mm, 4.5-5MM, 4-4.5mm to <4mm. This seed was sown and showed that the larger sown seed produced larger seed at harvest, but had no impact on biomass or grain yield. In 2022, we are repeating the trial from 2021 with a similar pattern of seed lots, but advancing one year one to understand seed size stability over seasons and confirm that seed size is have little impact of grain yields.
