Case study - Darrell Fiddler - The profitability of delaying permanent water

Case study

Bilbul irrigator, Darrell Fiddler, aims for the most profitable crop, which is not always the highest yielding. In the high water price years since 2013/14, the rice, cotton and winter cereal grower has been drill sowing rice and delaying the permanent water for up to nine weeks after the first flush.

In low water availability/high water price years Darrell can use the water savings to grow extra rice for higher returns overall, despite a slight yield penalty. In low water price years, where water is not limiting, Darrell has found that a conventional drill sown irrigation program with two flushes prior to filling is more profitable than delaying permanent water.
