Acknowledgments |
This research was part of the project Northern region high yielding cereal agronomy – NSW (DAN 00181), with joint investment by NSW DPI and GRDC. Technical assistance provided by Stephen Morphett, Jim Perfrement, Bruce Haigh, Peter Formann, Michael Dal Santo, Rod Bambach, and Jan Hosking (all NSW DPI) for the sowing, maintaining and harvesting the experiments is greatly appreciated. The research undertaken as part of this project was made possible by the significant contributions of growers through both trial site cooperation and support of the GRDC, we would like to thank them for their continued support and in particularly David Ronald, James Vince and Richard Heath. |
