A national workshop was convened by National Program for Irrigation Research and Development (NPIRD) to establish the need for national standards for rrigated crop water balance and crop evapotranspiration (ETc1) field ethodologies. The workshop was attended by representatives of relevant state agencies and federal organisations. Participants all had a sound understanding of the use of ET in their organization at a technical level and were also able to represent the organization at a policy level. The findings of the workshop showed that there are sufficient reasons and levels of agreement to pursue national standards
