| Abstract/Contents: | "Tall fescue [Schedonorus arundinaceus (Shreb.) Dumort.] is an important cool-season forage and turf grass and ranks among the most important seed crops in Oregon. Use of trinexapac-ethyl (TE) plant growth regulator (PGR) has been widely adopted in grass seed production across the globe and TE has consistently increased seed yield and reduced lodging. Chlormequat chloride (CCC) is another PGR that has been tested in PGR mixtures on several grass species but there has been no previous research conducted on tall fescue in Oregon. The objective of this study is to determine the effect of PGR combinations on seed yield, yield components, and lodging. This two-year study was conducted at Hyslop Farm near Corvallis, Oregon in 2017 and 2018. The study included 'Fawn' forage-type and 'Spyder' turf-type tall fescue. The experimental design was a randomized complete block with four replications. Plot size was 3.4 by 15.2 m. Seven PGR treatments applied at BBCH growth stage 32 include an untreated control, 210 g TE ha-1, 1500 g CCC ha-1, 105 g TE ha-1 + 750 g CCC ha-1, 210 g TE ha-1 + 1500 g CCC ha-1, 210 g TE ha-1 + 750 g CCC ha-1, and 105 g TE ha-1 + 1500 g CCC ha-1. Seed yield response varied between cultivars. In 'Fawn', TE + CCC mixtures did not increase seed yield over TE alone, which resulted in a 43% increase. The highest seed yield in 'Spyder' occurred with mixtures of 210 g TE ha-1 + CCC, which resulted in a 29% increase. Yield responses in both cultivars were largely attributed to increased seed number and reduced lodging. Seed weight was not reduced by any PGR treatment. Further work is needed to better understand how PGR mixtures can enhance seed yield." |
