Effects of Nitroxin and Nitrogen Fertilizers on Grain Yield and Essential Oil from Seeds of (Anethum graveolens L.).

Aims: Dill (Anethum graveolens L.) is a perennial herbaceous plant belonging to the (Apiaceae or Umbelliferae) family, with high essential oil content, and dill leaves and and seeds are used as seasoning. This study was conducted in 2011 and 2012 at Iran County, aiming to determine the effects of biological and chemical nitrogen fertilizers on grain yield, essential oil yield, and essential oil composition of dill.
Methodology: The treatments included Nitroxin bio-fertilizer (0% and 100%), and nitrogen (0, and 100 kg ha−1 (NH4NO3)), 50% nitroxin×50 kg ha-1nitrogen and control. A completely randomized block design with four replications was adopted.
Results: Results showed highest essential oil content detected in biological fertilizer and chemical fertilizer. Identification of essential oil composition showed that content of carvone increased with application of Nitroxin biofertilizers.
Conclusion: Results indicated, application of Nitroxin biofertilizers enhanced yield and essential oil content in this plant.
