Aims
To investigate the reasons for these differences in WUE by continuing with trials established at 4 sites in 2008 on different soil types and rainfall zones in selected grower paddocks.
Key messages
The highest recorded water use efficiency (WUE) was observed at Spalding where 26.6 kg of wheat was produced per hectare for every mm of growing season rainfall.
Growing season rainfall was below average meaning that stored summer soil moisture was very valuable in 2011.
The WUE at Hart has been 14 kg/mm/ha or 70% calculated since 2001.
