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 dates across varying climatic zones
• determine optimal genotype and sowing date combinations.
This paper presents results from the Wagga Wagga site in 2018.
• Varieties have differing optimum sowing dates, with the late April and mid May sowing dates producing higher yields overall.
• Identified sowing date and variety interactions for phenological development, grain yield and harvest index.
• Growing degree days affected time to emergence, with delayed time to emergence as the sowing date was delayed into late autumn.
• Sowing date had no effect on plant establishment.
