Rotations and associated management practices in rainfed farming systems of southwest Australia have shifted towards intensified cropping. Survey data from 184 fields spanning 14 Mha were used to document water use efficiency (WUE) water-limited yield potential (WLYP) commercial crops crop sequences identify biophysical variables influencing WUE. WUE achieved wheat was 10.7 kg grain/ha.mm. Usin...

In order to investigate the effects of different nitrogen fertilizer levels and water stress during milky and dough stages on grain yield, yield components and water use efficiency of corn hybrid SC 704 (late maturing, non prolific and dent type), a field study was conducted. The factorial design of the study comprised of a randomized complete block with four replications. Four levels of nitro...
