Abstract

The use of faba beans and lentils in crop rotations of South Australia has become an attractive option to break cereals and improves the sustainability of the farming system by providing organic nitrogen into the soil. An improved understanding of the genotypic variability in the response of both crops to common farmer management practices such as sowing date is a priority to maximise profits through better targeting of varieties to environment. This study analysed the response of ten varieties of lentils and faba beans to six different sowing dates in the Upper Eyre Peninsula, South Australia. The main objective was to understand the impact of sowing date on phenological development and the resulting effect on grain yield and yield components. In general, the later sowing dates reduced grain number per square meter and produced lower thousand kernel weight. The reductions in grain size, however, were always consistent with the increase in the delay of sowing.
