چکیده مقاله:

To evaluate the effect of irrigation levels and nitrogen fertilizer on the harvest index (seed and oil) of Salicornia europeae L., a split plot experiment was conducted based on randomized complete block design with three replications at the Urmia Lake marginal in 2012. Treatments were irrigation levels (irrigation after 20, 40, 80 and 120 mm evaporation from class A pan) as main plot and amount of nitrogen spraying (0, 5, 10, 15, 20 Urea (V/V) percent) as sub plot. Results of ANOVA showed the significant interaction effect between irrigation and nitrogen on the harvest index (seed and oil). In well watered plants, increasing of nitrogen caused to raise the harvest index. The harvest index was raised up by application of 15 % nitrogen and then they were decreased. A significant increasing of harvest index (seed and oil) was observed at 20% of nitrogen spraying for the mild (irrigation after 40 mm evaporation) water deficit stress.
