| Abstract | In arid and Semi-arid regions improving agriculture is forced by the presence of fresh water and adequate. Soil health Under Egyptian condition, although agriculture is mainly depended on water derives from River Nile, many lands are suffered from both water and soil salinity. Adopting some halophytic species, which has some economic benefits is only the first options for improving such conditions. In arid and Semi-arid regions water scarcity is one of the major problems faced by many countries in arid regions worldwide.Egypt is an arid country where water shortage hampers land productivity.A field experiment was carried out in newly reclaimed sandy soil at private salt affected farm, in Manshiet El Gammal, Fayoum Governorate to study the impact of irrigation at different levels of water supplies at (100, 75 and 50% from full water irrigation requirement IR) on plant height, biomass production, leaves photosynthetic pigments content, crude protein content and some physiological aspects of two halophytic plant species (Atriplex halimus and Leucaena leucocephala) treated with two soil amendments viz., (charcoal 4 kg /plant and Hydrogel 20 g/ plant) compared to nontreated plants (control). Results showed that increasing water stress, significantly decreased plant height and fresh biomass as well as leaves chlorophyll content, however, Atriplexhalimus was less affected by water stress and contrary crude protein% was increased as compared to Leucaena leucocephala. Furthermore, protein content in plant tissues of Leucenaspecierecorded the highest value at was 50% of water stress.Finally, the present results are confirmed the fact, which stated that both plant species Leucaena leucocephala and Atriplex halimusbeare highly drought-resistant when grown under water stress, additionally application of soil amendments could mitigate the harmful effect of water stress. The results indicated that these two plant species could produce economical biomass yields in arid environments, when irrigated at 75% soil moisture depletion. However addition of soil amendment reduces the negative impact of water stress on the studied characters and improve all the physiological aspects. |
