Abstract

In this study, the effects of different levels of NK fertilizers on the FLOWER YIELD and essential oil content of Rosa damascena Mill. was studied. The experiment was conducted as a split plot design with sub plots in strips based on randomized complete block design (RCBD) with three replications at the experimental field of Agricultural Education Center, Karaj, Iran during 2002-2005. Horizontal and vertical factors were nitrogen (0, 30, 60, 90 and 120 kg ha-1) and potassium (0, 30 and 60 kg ha-1). Fiftheen stocks of R. damascena from Barzok were planted in each replication. Leaf area index, leaf nitrogen and potassium content, flower diameter, flower number fresh weight per flower and essential oil content (w/w %) were measured. Analysis of variance and mean comparisons were conducted for all traits using SNK method. The results showed significant differences at level of 1%, among treatments for leaf area index, leaf potassium content and FLOWER YIELD components. The highest flower number and fresh weight were obtained by application of equal amounts of N an K fertilizer (60 kg ha-1), while, the application of 30 kg ha-1 of each fertilizer was the best combination to get the maximum of essential oil content.
