The provision of freshwater for agricultural use is declining in lots of parts of the realm. this is why for the expanding use of reduce caliber or of saline water for crop creation. lengthy use of saline water seriously impacts the irrigated soils, which contributes to the worldwide land degradation procedure and has direct effect on biomass production.
For this cause, relief of the unfold of salinization, revitalization of salinized parts and advent of salt tolerant high-yielding vegetation are vital matters. the capability function of halophytes within the administration of salinity difficulties of arid lands is investigated at size these days; a few of these have produced promising forage crops.
This quantity specializes in reclamation, administration, and usage of salt-affected soils, their sustainable use, and overview of crops inhabiting evidently taking place saline habitats.

Distans. In contrast, the low osmotic potential values in the other three species cannot be explained in view of the organic solutes analyzed in this study. It is possible that sugars, organic acids or other quaternary ammonium compounds that have not been determined in this study might have played a role in maintaining low osmotic potential. Increasing salt concentration in the rooting medium had no effect on relative water content of all the five grass species. The maximum water content of all grasses was observed at 16 dS/m while it was considerably lower in other treatments.

Pennisetiformis and P. turgidum is expected in view of the fact that both species are natural colonizers of the desert area where severe water deficit conditions are predominant [10]. The susceptibility of L. fusca to drought is also expected as the species commonly occurs in waterlogged sodic soils [1]. Leaf solute potential decreased significantly in all four grasses with increase in drought cycles. Leptochloa fusca had the lowest and P. divisum the highest osmotic potential among all the grasses at both drought treatments (Tab.

NaCl inhibited germination more in comparison to seawater solutions (Fig. 1). In non-saline control, highest germination was recorded at 2 days in S. salsa and 6 days in A. centralasiatica (Fig. 2). m−1 salinity level first seed germinated after 9 days in NaCl solution and only 11 % seeds germinated in seawater solution in A. centralasiatica. While in S. salsa 46 % and 58 % seeds germinated in NaCl and seawater solutions, respectively. Figure 1. Mean final germination percentage of Suaeda salsa and Atriplex centralasiatica in various NaCl and seawater solutions.
