Response of Rose (Rosa damascena Mill.) Oil Components to Different Irrigation Water and Nitrogen Applications

In this study, the effects of different irrigation water amounts and nitrogen doses on the components of rose oil obtained from rose flowers harvested in different periods were investigated in oil rose (Rosa damascena Mill.). The experiment was set up in Süleyman Demirel University Agricultural Research and Application Center and carried out according to the randomized block factorial experimental design with 3 replications. The experiment trials were created as 4 irrigation water amounts created depending on Class A pan (T0: 0.00, T1: 0.40, T2: 0.80, T3: 1.20) and 4 nitrogen levels (N0: 0 kg N da-1, N1: 8 kg N da-1, N2: 16 kg N da-1, N3: 24 kg N da-1, pure substance). Irrigation was carried out at 10-day intervals by drip irrigation method. According to the study results, differences were observed in the ratios of citronellol, geraniol and nerol which are the important components of rose oil according to the trial subjects. Citronellol ratios were 19.41-38.25 (1st year: 25.35-34.40; 2nd year: 19.41-30.10; 3rd year: 24.16-38.25) and geraniol ratio was 9.62-35.36 (1st year: 27.86-33.87; 2nd year: 28.12 -35.36; 3rd year: 9.62-26.62). The C/G ratio was found to be 0.91, 1.00, 1.16, 1.61 and 1.40 in the 1st, 2nd, 3rd and 4th harvest periods, respectively.
