Predicting crop yield response to irrigation level is increasingly important to
optimize irrigation under limited available water and for enhancing
sustainability and profitable production. This study was carried out to evaluate
the performance of
CropWat model in predicting deficit irrigation effect on
cotton crop, and to explore some alternatives for cotton irrigation. Crop yield
and water use data were collected from a 3-yr (2007-2009) field experiment to
assess the response of drip-irrigated cotton to deficit irrigation (DI).
