Narrow row cotton (rows spaced less than 40cm apart) has long been seen as a potential alternative system for Australian cotton, especially in regions with shorter growing seasons.

In 2005-06 we began investigations comparing the yield and maturity response of 38 cm (15') row spacings and conventionally spaced cotton while attempting to manage the two row spacings for Pix and nitrogen manag

Ultra-narrow row (UNR) cotton, a production system with rows spaced less than 40cm apart, has been proposed as the ideal system for earlier maturity without substantial yield loss.

Choosing the best time of sowing in a particular region can often be difficult, as it is a decision that must strike a balance between sowing too early and enduring problems associated with cold weather or sowing too

Earlier maturity in cotton would counteract increasing production costs and facilitate the expansion of cotton production into areas with shorter growing seasons.
