| Abstract/Contents: | "The objective of this study was to determine goosegrass (Eleusine indica) seedling emergence patterns in bare ground and cool-season turfgrass. Experiments were initiated in April 2017 and 2018 at the Rutgers Horticultural Research Farm No. 2 in North Brunswick, NJ. Off-site experiments were conducted on a golf course in East Brunswick, NJ in 2017 and Manalapan, NJ in 2018. Goosegrass seedlings were counted and removed on a weekly basis from April through October within fixed circles, replicated four times for each treatment and location. Plots at the Rutgers site were subjected to three different ground cover treatments; bare ground, perennial ryegrass (PRG; Lolium perenne) mowed at 1.3 cm, and PRG mowed at 6.4 cm. Fixed circles were sized 1000 cm within each 1.0 by 1.0 m plot. At the golf course locations, plots were maintained as a golf course fairway at a 1.25 cm mowing height and fixed circles were sized 500 cm within each 1.0 by 1.0 m plot. Soil temperature was monitored at a 5.0 cm depth at both locations. Soil volumetric water content was measured at the Rutgers site. In 2017, more seedlings emerged in bare soil (852 seedlings m-2) than in PRG plots maintained 1.3 or 6.4 cm (247 and 156 seedlings m-2, respectively). Non-linear regression analysis determined that 50% and 90% of goosegrass seedlings emerged by 2 July and 28 August 2018, respectively, at the research farm site. At the golf course site 1260 and 575 seedlings m-2 emerged at two different sites on the same fairway in 2017. At one fairway location, 50 and 90% of seedlings emerged by 21 May and 19 June, respectively. At the other fairway location, 50 and 90% of seedlings emerged by 31 May and 4 July, respectively. 2018 research is ongoing and will be presented." |
