Aims

To assess the effect of a nuber of different growth regulators over a rang of dates and timings on crop height and lodging in barley. To evaluate the effect of growth regulators on grain yield and protien. 

Key messages

The control, and both Cycocel ®treatments produced very similar results, and there appears to be no major difference between any of these treatments. The Terpal ® treatment had a slightly lower yield, lower retention and much higher screenings than the control and Cycocel ® treatments, however this may be due to disease hotspots in these treatments. I believe the use of growth regulators in barley still requires more work to confirm product selection, rates and timings for Australian conditions.
