General Summary/implications on faba bean Agronomy
Environmental conditions of above average rainfall during winter and early spring favoured early crop vigour and provided ideal conditions for the production of high plant biomass and large canopies. Further, cool and wet spring conditions during the pod-filling phase in late spring led to prolonged maturation contributing to very high yields across all sites. Pulse crop yields are strongly driven by environmental conditions in spring, particularly the length of grain filling period which is largely influenced by availability of soil water and optimum temperature. The current results should therefore be interpreted in the context of the highly favourable season of 2016. It is also interesting to note that despite the extremely high yields and favourable growing seasons, early sowing (mid-April) was still beneficial for faba beans in medium rainfall areas such as Hart in 2016 in contrast to higher rainfall areas of SA such as in the South East.

The advanced breeding line AF09169 sown in mid-April, flowered 25 days earlier than varieties with similar flowering profiles (from assessments in PBA breeding trials which have generally been sown from Early May to late June). This suggests the existence of genotypic variation in sensitivity to environmental factors such as photoperiod and temperature. This variety along with AF11212 and PBA Zahra were the highest yielding varieties at Hart, which indicate, that the three varieties optimised yields under more favourable conditions in 2016. The two highest yielding advanced breeding lines, AF09169 and AF11212 produced the least amount of biomass compared with other varieties at Hart. Results from sowing date by variety trials over a number of seasons are highlighting differences between varieties in biomass production at the early sowing date and these associations with grain yield will be explored in our future trials. Compared to other commercial varieties, the newly released PBA Zahra is characterized by high biomass production and early canopy growth and it is more suited to favourable environments and seasons. The experimental determinate faba bean line AF13250 had low yields similar to Farah, which may be explained by susceptibility to disease (rust) and weather damage due to its determinate growth habit, where the inflorescence and pods are exposed at the top of the plants. Further field evaluation and breeding development will continue to gain a better understanding of the potential of the determinant trait in managing excessive canopy growth which is critical to optimise yields in faba beans.
