To report on the outcomes of a series of faba bean variety × density experiments across northern NSW.
The 2015 season was characterised by severe frost events, episodic cold weather during flowering and terminal drought during grain filling. These seasonal conditions severely affected crop performance, reducing the potential yield of faba beans across most areas of the northern NSW cropping zone. The Northern Pulse Agronomy Initiative (NPAI; Winter Pulse) project conducted a range of experiments covering a number of different agronomic themes in 2015. This paper reports on the outcomes of a series of faba bean variety × density experiments across northern NSW.
Key findings:
Conclusions:
Limited data from the first year of trial results in 2015 suggests that for northern and western sites, 20 plants/m2 is a preferred target plant density, while in central areas 30 plants/m2 is a better option to achieve optimum yield with faba bean grown under dryland cropping conditions. Large seed does not necessarily confer higher yield, with PBA Nasma out yielding PBA Warda at only one location, Trangie, in 2015. Doza appears more prone to frost damage than either PBA Warda or PBA Nasma. Frost tolerance is a key attribute for the faba bean breeding program in northern NSW, with new releases (particularly PBA Nasma) targeted at having better tolerance than Doza, which was apparent in these trials in 2015.

Treatments Three faba bean varieties were sown; DozaA, PBA WardaA and the new line PBA NasmaA. Four target plant densities were examined; 10, 20, 30 and 40 plants/m2 . All five trials were grown under dryland cropping conditions (i.e. not irrigated). The difference in seed size for these commercial lines is shown in Figure 1, where PBA NasmaA, on average, has seed that is 40% larger than DozaA. |
