Yield response to PGR on Barley locations
Aims

To asses the effect of PGR application on barley

Key messages

The Plant Growth Regulator trinexapac-ethyl (Moddus Evo) has been shown in previous trials to increase yield in irrigated barley, but not necessarliy due to reduced lodging. This trial appears to indicate that the PGR resulted  increased tiller survival in lower plant populations of certain varieties. 

Some varities have shown no yield response to PGR application.

Selection of a variety that is not prone to lodging may be a better choice than applying a PGR.
