The research undertaken as part of project DAN00171: Northern pulse agronomy – NSW, is made possible by the significant contributions of growers through both trial co-operation and the support of the GRDC. The authors would like to thank them for their continued support. Thanks to Mat Grinter, Michael Nowland, Jayne Jenkins and Scott Richards (all NSW DPI) for their technical assistance in the trial program. |

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. |
