The reduction in seed germination and seedling growth varies with plant species, salinity level and ionic composition of the salts present in soil solutions. Seed germination of Leucaena leucocephala and Prosopis juliflora were affected in soil extract of all halophytic communities. Significant (p < 0.05) reduction in seed germination of Thespesia populnea was found in soil extract of Cressa-Suaeda-Atriplex and Suaeda-Heliotropium-Tamarix community. The root growth of P. juliflora was significantly reduced in soil extract of Haloxylon-Suaeda-Atriplex community. Significant inhibition in shoot growth of L. leucocephala and P. juliflora were found in soil extract of Haloxylon-Suaeda-Atriplex community. L. leucocephala and T. populnea showed low tolerance in soil extract of Cressa-Suaeda-Atriplex community. P. juliflora demonstrated low tolerance in soil extract of Haloxylon-Suaeda-Atriplex community. The soil collected from different community showed variation for soil conductivity and cations. The highest sodium (11,500 µg/g) was observed in Suaeda-Heliotropium-Tamarix community. Salsola-Fagonia- Zygophyllum community exhibited the lowest concentration of sodium and potassium, 500 and 75 µg/g, respectively. It was found that sodium was directly proportional to the conductivity of the soil extract.
