This study was conducted to find out the effect of sodding and seeding time and rate of seed mixtures on the establishment of cool-season turfgrasses by evaluating the turf coverage rates for two years.
In fall planting, the required establishment period of full coverage(100%) was 1.5 months with a rolled turf sodding(Kentucky bluegrass 100%, Kentucky bluegrass 80%+Perennial ryegrass 20%). The 100% turf establishment was achieved in 7 months with Perennial ryegrass 100%, and 7.5 months by seeding with Kentucky bluegrass 100%(KB100), Kentucky bluegrass 80%+Perennial ryegrass 20%(KB80+PR20), Kentucky bluegrass 70%+Perennial ryegrass 30%(KB70+PR30).
In spring planting, the establishment periods for sod with KB100 or KB80+PR20 were taken one month. However, in the case of seeding, the establishment periods were 3 months, 3.5 months, 3.5 months and 4 months with PR100, KB80+PR20, KB70+PR30, and KB100, respectively. Comparing the turf establishment vigor between fall and spring planting, the vigor was higher in spring planting than in fall planting in both sodding and seeding.
In the case of spring planting, the most proper time for turf establishment was tested on April, May, and June trials. The effect was significant in establishment vigor. The result showed highest on April planting. On May and June trials, establishment vigors were decreased gradually. As the mixture rate of PR increased, ryegrass, establishment vigor was decreased with the rates. These results indicated that perennial ryegrass has relatively less tolerant to summer heat than Kentucky bluegrass.
Number of shoots in 95 days after seeding was higher in KB100 by 16,600 per ㎡ than in PR100 by 12,400 per ㎡, while the lowest number showed in KB50+PR50 by 3,300 per ㎡. Those in KB80:PR20, KB70:PR30 were 6,700 and 4,900 per ㎡, respectively. The ratios of tillers according to mixture rates between Kentucky bluegrass and perennial ryegrass were KB80:PR20=87:13, KB70:PR30=78:22, and KB50:PR50=48:52.
According to results in this study, ideal seeding time might be spring (April) than in fall (September), and proper mixture rate was 80% of Kentucky bluegrass with 20% of perennial ryegrass.
