Faba beans have a relatively small but significant fit in the central and north-west plains regions of NSW, being a valuable part of the whole farm system due to their rotational and logistical benefits... Faba beans provide an option to plant early (late March to late April) and harvest early (late September to mid October), which will broaden the windows of sowing and harvest... Being a high biomass crop with deeper root penetration, faba beans generally use more water than chickpeas and field peas leaving less residual PAW for the following wheat crop...

Faba beans provide an option to plant early (late March to late April) and harvest early (late September to mid October), which will broaden the windows of sowing and harvest...

Image showing an NPV infected helicoverpa larve that has ruptured.. Maize: NPV will not control larvae sheltering in maize cobs but should give good control in silking maize if applied via a ground rig fitted with droppers targeted at the cob and silk area of the plant... Viral infection is much more complex, and resistance to NPV is much harder to develop...
