Several new lentil varieties have been released or are due to be released with changes in agronomic traits such as plant architecture, biomass production, reproductive duration and timing, disease resistance, herbicide tolerance and pod retention. Changes in sowing date have the potential to maximise the benefits of these traits from a crop production and farming system perspective. In particular, there is an interest in understanding the implications of later flowering with a reduced reproductive window, combined with lower vigour. In addition the 2 new GIA varieties Sire and Metro have unique growth habits that may require different planting densities to optimise grain yield.
This paddock was previously sown with wheat in 2021 and located in Warne with sandy clay loam.
