This research aimed to identify the impact of irrigation opportunity time and fertiliser N rates on fertiliser N response, lint yield and fertiliser N recovery in a sub-surface drip irrigation system.
The field experiment was designed as a randomised split plot design with irrigation treatments as the main plots (six main plots) and N rate as the sub-plot.

Acknowledgments |
The cooperation and management of the experiment site by Richard Stott, James Hill and Matt Watson, without which the experiment would not have been possible, is gratefully acknowledged. The technical support provided by Anika Molesworth, John Hornbuckle, James Brinkhoff, Aydin Enez, Irsah Chowdhury, Gabby Napier, Hannah Draper and Jothyar Singh throughout the season was critical to the success of the experiment. The project is supported by joint investment by the Australian Government Department of Agriculture and Water Resources as part of its Rural R&D for Profit Programme, Cotton Research and Development Corporation, Rural Industries Research and Development Corporation and NSW DPI. |

Fertiliser |
Five N fertiliser treatments were applied at 0, 80, 100, 150 and 250 kg N/ha. The N was applied as Anhydrous ammonia (82% N) approximately three weeks before planting of the cotton crop. No in-crop N applications were made to the experimental areas in the field. |
