This study was conducted to determine the effects of different irrigation water amounts (k(cp)1: 0.25, k(cp)2: 0.50, k(cp)3: 0.75, k(cp)4: 1.00 and k(cp)5: 1.25) and irrigation intervals (I-1: 1-, I-2: 2- and I-3: 3-day) on the yield and some quality parameters of carnation plants (Dianthus caryophyllus L. cv. 'Turbo') grown in soil under greenhouse conditions. Class A Pan was used to determine irrigation water amounts. Yield and quality parameters (stem length, stem fresh weight, flower diameter and stem diameter) were significantly (p < 0.01) affected by the irrigation water amount and irrigation interval. While node number was affected by irrigation water amount, irrigation interval did not affect node number. The highest total flower number per m(2) was recorded in I(1)k(cp)4 (89.56 flowers m(-2)), whereas the lowest total flower number per m(-2) was found in I(3)k(cp)1 (10.0 flowers m(-)2). Among the irrigation water amounts, the longest stems were determined in k(cp)5 (71.04 cm) and k(cp)4 (69.30 cm); however, the difference between both treatments was statistically insignificant. Among the irrigation intervals, the longest stem (67.56 cm) was obtained from the carnations irrigated with high irrigation interval (I-1). The treatments with both the same irrigation water amount and higher irrigation intervals produced higher flowers yield and quality.
