The effects of plant densities on yields of Foeniculum vulgare Mill under dry farming

The extensive waste dry lands of Iran, shows necessity of selection and cultivation of tolerant and suite plants for more production, cover green and erosion inhibition under dry farming system. Effects of plant density on seed yield and yield components of Foeniculum vulgare Mill. Had been studied under Damavand dry farming in 2003-2007. This experiment was conducted under RCBD with using 3 plants densities and 4 replications. The results showed significant differences among the densities treatments in dry matter, seed yield, plant height, seed weight per plant and 1000 kernel weight in the third year. The Fennel yield's of dry matter in the first, second and third year of experiment were 1229, 779 and 2079 kg ha-1 and seed yield reached to 611, 280 and 712 kg ha-1, respectively. Finally Foeniculum vulgare could be considered as a tolerant and adaptable medicinal plant under dry land of Damavand and similar cold regions.
