Abstract/Contents:Summarizes 2 studies on establishment of zoysiagrass by seed propagation. Test 1 determined the best method of establishment and evaluated the resulting turf when seeding with a common strain of zoysiagrass. The bluegrass area to be seeded was sprayed with Roundup to kill all existing vegetation, fertilized according to soil test results, and subsequently scalped to about 1". Sodium hydroxide scarified Korean zoysiagrass seed was soaked and sunlight treated for 6 days before seeding on 6/24/82 using four methods and the following seeding rates: prepared seed-bed (1#/1000 sq ft), slit-seeded (1/4#/1000 sq ft), vertically mowed (1#/1000ssq ft), and no seed-bed preparation (1#/1000 sq ft). The entire plot was irrigated daily until establishment. In 1982, MSMA was applied to control crabgrass 3 times and nitrogen was applied in June, July, and August at 1.5 lbs N/1000 sq ft. Plot height was 1 1/4 inches in 1982. Height was maintained at 1 inch in 1983 with N applied in May, July, and August at the 1982 rate. Zoysia was established very quickly in prepared seed bed and was about 100% established by late September 1982. Establishment by vertical mowing was much superior to both the slit-seeding or broadcast method. Tilled seed bed had a 100% cover of zoysia by June 1983, and verticut plots were nearly established. Other seeding methods showed little improvement. Test 2 determined the relative establishment of zoysia (same as test 1) seeded at 1 lb/1000 sq ft as affected by certain renovation methods (vertically mowed, slit seeded, broadcast seeded and chaindragged, broadcast seeded only) and chemical treatments (glyphosate at 2 lb ai/A, mefluidide at 0.38 lb ai/A, no chemical) to Kentucky bluegrass turf. Entire plot was irrigated daily, fertilized, and treated for crabgrass (MSMA). Vertically mowed plots established more quickly than other renovation methods. Both glyphosate and mefluidide improved the establishment rate. When Kentucky Bluegrass was killed with glyphosate, both slit-seeded and chain-dragged plots established fairly well. With no chemical treatment, slit seeding was much superior to chain-dragged method. This strain of zoysia appeared to be much more aggresive than Meyer. Tables summarize results.
