Abstract :In order to evaluate the effects of organic, chemical and integrated nutrition systems on morpho-physiological traits of oregano insert ignore into journalissuearticles values(Origanum vulgare L.);, an experiment was carried out at the experimental farm of the Agricultural and Natural Resources Research Center, Urmia, Iran, during 2016-2017 growing season. The experimental design was a completely randomized block design with three replications. The experimental treatments included NPK, two organic insert ignore into journalissuearticles values(vermicompost and biochar);, two biological insert ignore into journalissuearticles values(nitroxin and bio super phosphate); fertilizers and their all twin combinations and control insert ignore into journalissuearticles values(non-fertilized);. Our results showed that the application of organic fertilizers caused a significant increase in yield and essential oil content in oregano. On the other hand, integrated nutrition treatments had the most effect on increasing the traits in compared with the individual treatments. The highest essential oil yield was obtained from Nitroxin treatment insert ignore into journalissuearticles values(871.27 kg ha-1); in the second year. Whereas, the lowest value of essential oil yield was found in control insert ignore into journalissuearticles values(non-fertilized); insert ignore into journalissuearticles values(25.92 kg ha-1); in the first year. The present study clearly indicated that chemical fertilizers could be replaced by biofertilizers resulted in similar oil yield.
