To determine appropriate sowing dates and densities of new faba bean varieties in the South East of SA, and quantify effect of various crop-top timings on yield of commercial cultivars.
Grain yields of beans were lower in 2012 in than previous seasons, averaging 3.6t/ha at Bool Lagoon.
All varieties showed higher yields sown early.
Later maturing varieties PBA Rana and PBA Kareema performed similarly to other varieties in this trial in 2012, despite the low season rainfall.
The three earlier maturing varieties (Farah, Fiord and Nura) showed increased yield from increasing plant density, while no yield response was seen in later maturing and larger seeded varieties (PBA Rana and PBA Kareema).
Fiord showed the most response from varying plant density across the three seasons of trials.
Crop-topping trials showed a 9% yield loss across all varieties from crop-topping at the milky dough stage of ryegrass in 2012 and caution is required with this practice in later maturing regions. No yield loss was generated from later treatments.
