Optimised Irrigation Row Comparison

The 2015-2016 Gwydir Valley Cotton Growers Association (CGA) Optimised Irrigation Row Configuration Trial was an extension of the highly successful 2014-2015 season trials conducted by the GVIA. The 2015-2016 trial was established at Auscott Watervale in the Gwydir Valley, with the trial continued for a third season in 2016-2017 at Auscott Midkin under the CRDC and Smarter Irrigation for Profit Programme.

This project was designed to further investigate the relative yield potential of different row configurations under optimal irrigation conditions. The objectives were to investigate water-use efficiency of siphon irrigation under different row configurations. The row configurations assessed in the trials included the standard 40inch (1m), as well as areas of 30inch (75cm), 60inch (150cm) and 80inch (200cm). The project evaluated the trial in terms of yield and applied irrigation water relative to the standard 40inch row configuration.

A highly insightful and useful program, the Gwydir Valley CGA and the GVIA were able to collect data which increased the level of understanding of the benefits and possible disadvantages associated with different row configurations under siphon irrigation.
