Abstract
The current study was conducted to investigate the influence of different seed sowing rates 5, 10,15, 20 and 25 g m-2 and five cutting times (T1:15 June, T2: 15 July, T3:15 August, T4: 15 September and T5:15October 2013) on yield and the quality characteristics of Kentucky bluegrass (Poa pratensis L. cv. Geronimo). Theexperiment was carried out in a Completely Randomised Block Design with three replications. The experimentwas conducted at the Agricultural Application and Research Centre of Iğdır University in 2013. The investigatedcharacters were measured, the covering rate, green grass yield, the plant height, colour, leaf width and turfgrassquality in the trial. The results indicated that 5, 10, 15, 20 and 25 of seed density per m-2 produced covering rate8.5, 22.7, 49.6, 51.8 and 57.0 (%); green grass yield 83.3, 218.7, 415.3, 457.3 and 514.0 g m-2; plant height 7.9, 7.9,8.4,8.6 and 8.3 cm; color 5.6, 5.6, 5.9, 5.9 and 6.0 (1-9 scala); leaf size 1.13, 1.19, 1.12, 1.14 and 1.14 mm; turfgrass quality ranged from 1.19, 3.07, 4.93, 5.42 and 5.50 (1-9 scala). Under the environment conditions of Igdır,the highest green yield of grass, coverage ratio, colour and turfgrass quality were achieved by the application of25 g seeds per m-2. In respect of cutting times, the highest green yield and coverage rate were produced at T5 time,as well as the highest colour at T5, T1 and T2 times, respectively and turf grass quality was obtained at T5 and T4times in the application of 25 g seeds per m2 during the establishing year. Accordingly, it can be concluded that therates of seed to be recommended in 25 g per square, when all the features examined are taken into account of Poagrown in landscape establishment under the Iğdır ecological conditions.
