اثر سطوح مختلف آبیاری و کود نیتروژن بر برخی خصوصیات فیزیولوژیک سالیکورنیا

Soil salinity is one of the most important problems of arid and semi-arid regions in the world. Based on Food and Agriculture Organization report, more than 40% of Iran’s under Irrigation lands, are against secondary salinity. Nowadays biological methods are widely used to confront, soil salinity problems. Salicornia europaea, a halophilic plant and potential for cultivation as an oilseed plant is watered with sea water.To evaluate the effect of irrigation levels and nitrogen fertilizer on some physiological attributes of Salicornia europaea 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 effect of irrigation on the proline, total soluble sugar, and amount of total chlorophyll.
