Influence of oil content and yield of Foeniculum vulgare Mill. cv. Soroksary seeds by adapting different plant densities

In this experiment, the effect of different plant densities on the oil content and yield of Foeniculum vulgare Mill. Cv. Soroksary seeds was studied at the Faculty of Agricultural Sciences and Engineering, Karaj, Iran (Latitude 35° 47´ N and Longitude 50° 59´ E) in 2008. Different spacing studied were 10, 15, 20, 25, and 30 cm and the distance between rows in all treatments was 40 cm using a complete randomized block design with three replicates. According to the results, the effect of plant density on oil content and yield was significant (P<0.01). The highest oil content (3.33%) and yield per hectare (116.73 L) was obtained with the lowest plant density. Key words: Foeniculum vulgare cv. Soroksary, plant density, oil content, oil yield.
