| Abstract/Contents: | "Plant growth regulators (PGRs) are widely used to control lodging and increase yield of grass grown for seed. However, the information on PGR applications for Kentucky Bluegrass (KBG) is limited. In this study, a field trial was conducted at the Oregon State University-Hermiston Agricultural Research and Extension Center to determine the effect of trinexapac-ethyl (TE) PGR on KBG and to evaluate the PGR and nitrogen (N) interaction. A KBG elite 'Midnight' was planted in Adkins sandy loam soil under center pivot irrigation during fall 2017. A total amount of 208 kg ha-1 N (regional grower standard N rate) was applied at 5 weeks (fall) and 6 months (spring) after planting. On May 5, 2018 when the KBG was at the early stem elongation stage (BBCH 32), eight TE treatments were applied including combinations of four TE rates (0, 0.9, 1.6, and 2.8 L ha-1 Palisade ® EC) and two N rates (0 and 56 kg ha-1). Treatments were arranged in a randomized complete bock design with three replications. Field measurements indicated that all PGR treatments reduced lodging with the high TE rates showing the greatest reduction. The 56 kg ha-1 N application increased lodging over the 0 kg ha-1 N treatment. The stem height of the KBG was reduced by slightly when TE was applied at 1.6 L ha-1 or higher, regardless of N application. There was no seed yield response to any TE or N applications. The preliminary data suggests that TE coupled with N management may be beneficial to reduce lodging in KGB seed production. However, additional data is needed to further develop PGR and N recommendations for KBG seed producers." |
