The effect of Ammonium nitrate on Dill (Anethum graveolens L.) under salinity stress

In order to study effect of salinity and nitrogen on growth and physiological characteristics Dill, In 2013 the experimental to Factorial method in format completely randomized design with six replications was performed at the Greenhouse of faculty Agricultures Lorestan university. The planting time, the middle of February and the harvest time was the early of May. The plant seeds were planted at 5kg Pots containing 3kg soil, 1kg sand and 1kg dung. In the stage of Eight-Leaves, the treatment of salinity (sodium chloride) were applied to concentrations 0, 30, 60, 90 and 120gr salt in 100kg soil, and treatment of Ammonium nitrate to concentrations 0, 10, 20gr in per 1000ml water. The results show that with increasing level of salinity and Ammonium nitrate, the amount of soluble sugars to a certain level gradual showed increase. Whereas total Chlorophylls and insoluble sugars trend descending showed
