Here’s a new article from our seed production research and extension team on irrigation and trinexapac-ethyl PGR effects on seed yield and yield components in red clover seed crops. Field trials were conducted in the Willamette Valley over a 3-year period at OSU’s Hyslop Farm. Trinexapac-ethyl is marketed around the world as Palisade, Moddus, and several generic products for lodging control and seed yield enhancement in cool-season grass seed crops and legume seed crops.
This article appears in the current issue of Agronomy Journal and can be found at the link below:
Anderson, N.P., T.G. Chastain, and C.J. Garbacik. 2016. Irrigation and trinexapac-ethyl effects on seed yield in first- and second-year red clover stands. Agron. J. 108:1116-1123.
Key findings of the article:
- Irrigation strategically-timed to coincide with peak flowering consistently increased seed yield in red clover regardless of stand age.
- Trinexapac-ethyl PGR increased seed yield in second-year red clover stands but not in first-year stands.
- Irrigation and trinexapac-ethyl independently increase the yield of red clover seed crops but there were no interactions between the two.
