Irrigation is a key component of cotton production in Australian agriculture, where increasing pressures of water scarcity requires growers to improve their water use efficiency.

This project aimed to improve cotton irrigation WUE using dynamic deficits to (i) avoid plant stress and maximize yield and (ii) make the most effective use of in-crop rainfall.
