Lupin seed integrity and establishment

With split seed resulting in yield penalties higher than 70% in some areas, a new GRDC investment is looking at how growers can manage their handling of lupin seed to ensure better germination of seed in the following seasons.

A benchmark study of 27 WA growers looked at germination impacts for lupins, focusing on reducing the incidence of split seed through harvest activities such as machinery impacts, and manganese deficiency.

The study which started in 2019 has now wrapped up, with advice around manganese management, going easy on the augers, harvesting with at least 12% moisture and asking the experts to assess seed. But those who know lupins, know there’s still a lot to learn.
