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.
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.
