Here’s a new article from our seed production research and extension team on trinexapac-ethyl plant growth regulator (PGR) and field burning effects on the expression of yield components in strong creeping red fescue (Festuca rubra L. subsp. rubra) seed crops. The field trials were conducted in the Willamette Valley over a 4-year period at Hyslop Farm.
This article will appear in the next issue of Agronomy Journal and is a part of our series on PGR tools for use in grass and legume seed production. The product is marketed as Palisade, Moddus, and several generic products for lodging control in grass seed crops and legume seed crops.
Key findings of the article:
- Fall applications of the PGR had no effect on seed yield components.
- Culm length was reduced and lodging was lessened by spring applications of PGR in strong creeping red fescue.
- Spring applications of PGR increased the number of florets produced.
- A combination of burning and spring PGR applications increased seed number and seed weight, thus contributing to higher seed yields in strong creeping red fescue.
