Influence of seed size on the yield of the faba bean variety PBA Nasma - Breeza 2015 locations
Aims

To study the influence of seed size on the yield of the faba bean variety PBA Nasma.

Key messages
  • There is no evidence to support growers grading seed into different size categories and sowing the smaller seed.
  • In one trial in 2015, sowing seed of different size classes did not significantly influence the yield of PBA NasmaA. Insufficient data is currently available to make a recommendation either way on this practice, but there was a trend towards reduced size of harvested seed and yield from sowing smaller PBA NasmaA seed.
