Abstract/Contents:1986 evaluation at Kentucky locations of 4 bermudagrass establishment methods for small areas. First method evaluated was a stripped-down mechanical tobacco planter used to hand-plant rows of sprigs in both bare/compacted soils and in thick bluegrass sod. Maximum row spacing for establishment during one growing season (late May to September) was found to be 15-18 inches. The second method evaluated placement of sprigs on bare soil followed by continuous irrigation. A battery operated irrigation controller applied water for 30 minutes every three hours, for two weeks. The rate of water was 1/4 inch per 1/2 hour, or 4" per day. Sod was stripped from the test area with a mechanical sod cutter and the surface soil received no additional preparation; i.e. the surface remained very firm with no loose soil. Approximately 8 sprigs per square foot, with 2 or 3 nodes per sprig, were placed on the surface. A table provides % live sprigs on 8/6 and % of ground cover on 8/13 for 5 cultivars: RS-1, Midiron, Vamont, London, and Meyer (Zoysia). With no soil incorporation, sprig survival and establishment was outstanding, especially with RS-1 (quicksand). The third method evaluated the survival of different plant parts under different surface/irrigation methods of establishment. RS-1 sprigs were harvested and separated into stolon, rhizomes, and green tillers. Eight viable plants per square foot were placed on the firm surface. To give added protection, 1/2 of the plots were covered with a light straw covering (1/2 of the surface visible through the straw). Irrigation was applied for two weeks at the same rate as described in the previous test. A table provides % bermuda cover on 8/6 and 8/13 for stolons, rhizomes, and green tillers without straw. Straw improved survival and stolons were much more effective than rhizomes or green tillers. The final method evaluated was a test for establishment competition on bluegrass sod in which surface vegetation was scalped and sprigs placed over the surface as previously described. Since the sod was not killed, the bluegrass responded to the frequent irrigation and began recovering immediately after the bermuda sprigs were placed on the surface. This caused the sprigs to be elevated away from the soil surface and obviously reduced establishment. Throughout the two-week period of irrigation however, the sprigs stayed alive and all stolons began to produce new plants at their nodes. After the irrigation was stopped, most of these aerial tillers desiccated.
