Effect of Nano Nitrogen, Magnetic Water, Urea and Chicken Manure Foliar Application on Yield, Yield Components and Essential oil of Different Fennel (Foeniculum vulgare Mill) Landraces

In order to study the foliar application effects on yield and yield components and essential oil of Fennel (Foeniculum vulgare Mill) an experiment  was conducted as factorial based on completely randomized design with three replications and  twenty five treatment at the research farm of agricultural education center, Urmia, Iran during growing season of 2015-2016 and 2016-2017. First factor included five landrace of Fennel Gaziantep, Hamadan, Urmia, Yazd and Shiraz and the second factor included five foliar applications as Nano-nitrogen, magnetic water, urea, chicken manure and control. The result indicated that the highest height, umbel and number of lateral branches and umbel, were related to Y1A5B2 (first year, Shiraz landrace with magnetic water treatment), Y1A1B2 (first year, Gaziantep landrace with magnetic water treatment), Y2A4B2 (second year, Yazd landrace with magnetic water treatment) and Y1A1B2 (first year, Gaziantep landrace with magnetic water treatment), respectively. The highest essential oil, 1000-seed weight and number of umbellate per umbel were recorded in A3B5 (Urmia landrace with control treatment), A1B1 (Gaziantep landrace with magnetic water treatment) and a3b3 (Urmia landrace with urea treatment) respectively. The highest seed yield (1144 Kg.ha-1) and the lowest one (923 Kg.ha-1), respectively, were related to Gaziantep and Yazd landrace. The founding information's in the present study were elucidated that Nano-nitrogen in comparison of other treatment has highest effect on seed yield, weight of 1000 seed, umbrellas, essential oil percent and yield. Gaziantep landrace produced highest seed yield, 1000-seed weight and lateral branches and Urmia landrace has highest essential oil percent, essential yield and umbrellas. The highest height and umbel was recorded in Yazd landrace. Due to the importance of the essential oil, the Urmia mass along with the spraying of magnetic water and nano-nitrogen for the Urmia region is suggested.
