| Abstract/Contents: | "Replicate field research experiments were conducted in 2021 and 2022 in North Brunswick, NJ on Kentucky bluegrass (Poa pratensis) to evaluate false-green kyllinga establishment from seed. Two turfgrass maintenance regimens and three seeding treatments were evaluated in a split-plot randomized complete block design with four replications. Maintenance regimens formed whole plots. The high maintenance regimen consisted of 175 kg N ha-1 annually and preventative fungicide applications during summer. The low maintenance regimen was fertilized once annually at 25 kg N ha-1 and no fungicides were applied. Sub-plot treatments were false-green kyllinga seeded at 5 kg or 500 kg ha-1, and smooth crabgrass at 500 kg ha-1. Weed cover was determined visually and using an intersect count. Turfgrass cover was determined using digital image analysis (Turf Analyzer software). Data were subjected to ANOVA in SAS 9.4 using Fishers protected LSD (P=0.05) was used to separate means. Main effect interactions were detected (P < 0.05) in August and September weed cover and intersect count data in both years. In August of both years, false-green kyllinga cover was greater under low maintenance than high maintenance when seeded at 500 kg ha-1. When seeded at 5 kg ha-1, false-green kyllinga cover was greater under low maintenance (16%) than high maintenance (6%) in August 2021, but maintenance did not affect cover in 2022. Under high maintenance, crabgrass cover was 80 and 93% in August 2021 and 2022, respectively, while the same rate of false-green kyllinga seed resulted 34% and 10% false-green kyllinga cover in August 2021 and 2022. Turfgrass cover was greater in May 2022 than 2021 and could explain year differences. False-green kyllinga establishment was influenced more by turf management regimen than smooth crabgrass. This research indicates false-green kyllinga is less competitive than smooth crabgrass from seeded establishment." |
