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.
