This experiment was part of a series of ongoing experiments sown in central and southern NSW aiming to:
• identify the phenological drivers of chickpea in central and southern NSW
• determine variety response to sowing date across varying climatic zones
• determine optimal genotype and sowing date combinations.
This paper presents results from the Yanco site in 2018.
• The low mean yield averaged across sowing dates and varieties (1.23 t/ha) at this site was largely attributed to limited pre-sowing moisture and low (87 mm) in-crop rainfall.
• Genesis™ 090 showed more signs of susceptibility to drought stress than other varieties.
• Late April and mid May sowing dates produced higher yields overall.
• There was an interaction between sowing date and variety for phenological development and harvest index, but not for grain yield.
• Growing degree days affected time to emergence, with delayed time to emergence as sowing date was delayed into late autumn, but there was no effect on plant density.
