Soil moisture extraction under fully irrigated conditions was the same in BollgardII and conventional varieties, except where season length allowed later crop and leaf growth in the conventional variety.

BollgardII accumulated yield faster than conventional cotton due to higher retention combined with a very low proportion of tipped plants.

Increased pressures are being placed on irrigators in Australia to maximise their water use efficiency. This has in turn highlighted the need for more focused research and extension on water management.

Under limited water scenarios HydroLOGIC was able to optimise yield.- Irrigation application efficiencies were estimated to be near the industry average of 60 percent-Combining soil moisture probe information with Hyd
