This project, a continuation of CRDC Project CSP1602, provides science leadership for potential new cotton developments in northern Australia. Proposed Summer cotton cropping enables Winter double cropping, with grain/fodder and cottonseed as a protein source for beef cattle. This project coordinates industry activities, including extension of research, while providing technical support to new and recent commercial cotton investments in tropical Australia. It also contributes to the Cooperative Research Centre for Developing Northern Australia (CRCNA) collaborative project ‘Potential for broadacre cropping in the Northern Territory’ through activities such as validating and calibrating modelling tools for climate risk assessment, and assessing and supporting crop protection risks unique to northern systems.
