PBA Nasma faba bean - effect on seed size at sowing on grain yield locations
Aims

To examine the effect of seed size at sowing, at a fixed population, on grain yield and seed size distribution at harvest. 

Key messages
  • At present, there is inconsistent evidence to suggest that seed size at sowing can affect grain yield in the faba bean cultivar PBA Nasma, with a positive yield benefit associated with sowing larger seed at Trangie, but no significant yield effect at Tamworth in 2015.
  • Seed size at sowing appears to be positively related to seed size at harvest.
  • Further experimentation is required.

Other trial notes

Treatments

Seed for this newly released cultivar, PBA NasmaA, was in limited supply, which restricted experimentation to two sites; TAI and TARC in 2015.

The seed was passed through a set of nested circular mesh sieves and partitioned into four seed size categories; 9 mm with corresponding 100 seed weights of 34.6, 48.1, 69.5 and 90.0 g, respectively.

Randomised complete block experiments consisting of the four seed size treatments and four replicates were sown at target plant densities of 20 plants/m2 at TAI and 10 plants/m2 at TARC.
