Özet: Salinity is one of the most serious environmental problems, since it is negatively affect agricultural production by limiting the growth and productivity of plants especially in arid and semi-arid regions of the world. Most developing countries suffer from a lack of cultivated area and fresh water supply due to the negative impact of climate changes. Therefore, growing non-traditional crops such as halophytes could be a proper solution to solve the problem of saline environments. For this purpose, two field experiments were carried out during 2014 seasons at the model farm of National Research Centre, El Tour, South Sinai to study the effect of addition of soil amendments ( Charcoal 5 kg/plant or Hydrogel 50 g/plant in addition to control treatment) and organic fertilizer [Chicken manure, Compost or mixture of composted Sporopolus virginicus, Spartina patens and Leptochloa fusca (1:1:1) + bio (yeast) 5 kg/ plant each in addition to control treatment as mineral fertilizers ] as well as their interaction effect on some growth characters and photosynthetic pigments content as well as some physiological aspects ( proline, soluble carbohydrates, succulence, sodium, potassium and K/Na ratio). Data showed that addition of 5kg chicken manure recorded the highest values of all the studies growth characters, photosynthetic pigments and potassium content as well as K/Na ratio and succulence as compared with other treatments. On the other hand the highest proline and sodium content recoded by addition of 5 kg compost, while the highest values of soluble carbohydrates were obtained by control treatment. However addition of soil amendments either charcoal or hydrogel positively affected all the studies growth and physiological characters with superiority to hydrogel. As for interaction effect, treating plants with 5 kg chicken manure in addition to hydrogel recorded the highest growth and photosynthetic characters as well as it improves all physiological aspects of Atriplex plant.
