Özet

This study aimed to determine the effects of different irrigation water amounts and nitrogen doses on flower and oil yields and water use in Rosa damascene in Isparta which is located in the Mediterranean Region of Turkey. Different water and nitrogen doses were applied to the Rosa damascena plant, and the drip irrigation method was used at 10-day intervals. The treatments included four different irrigation water amounts [To (K-cp0 : 0.00), T-1 (k(cp1) : 0.40), T-2 (k(cp2) : 0.80), and T-3 (k(cp3) : 1.20) as crop-pan coefficients] and four different nitrogen doses (N-0 : 0 kg ha(-1), N-1 : 80 kg ha(-1), N-2 : 160 kg ha(-1), N-3 : 240 kg ha(-1,) and pure substance). The experiment was conducted in a randomized block factorial design with 3 replicates. The seasonal evapotranspiration, water use efficiency, irrigation water use efficiency and yield response factor (k(y)) varied between 346.2 and 614.7 mm, between 4.87 and 13.86 kg m(-3), between 8.05 and 32.18 kg m(-3), and between 0.92 and 1.59, respectively. The different irrigation water amounts and nitrogen doses did not have a significant effect on flower yield in 2010, but had a significant effect (P < 0.01) in 2011 and 2012. The flower yield ranged from 2339 to 3046 kg ha(-1), 2215 to 6373 kg ha(-1), 2104 to 6616 kg ha(-1) in 2010, 2011 and 2012, respectively. Similarly, the effects of different irrigation amounts and nitrogen doses on the rose oil yield were significant in 2011 and 2012 (P < 0.01) but not in 2010. The rose oil yield was 1.10-1.66 kg ha(-1), 1.13-3.42 kg ha(-1), 0.72-2.89 kg ha(-1) in 2010, 2011, and 2012, respectively. The results of this study showed that the increasing irrigation water amounts and nitrogen doses significantly increased the flower yield. Considering yield and water use efficiency, it was concluded that the most efficient irrigation scheduling was T-1 and that the most efficient nitrogen doses were N-2 and N-3. (C) 2016 Elsevier B.V.
