Influence of sowing date and variety selection on growth and development of cotton – Yanco 2019–20

Abstract

Key findings •Sowing cotton in the southern regions of New South Wales should aim to increase the season length as much as possible. •Pushing the sowing date past the last week in October resulted in 64% yield loss compared with a late September sowing date. •Varietal difference within sowing dates was minimal, having no real effect on yield. •In 2019–20, low quality cotton was avoided by sowing a variety with a more determinate growth habit in late September such as Sicot 707B3F and Sicot 714B3F.
