This work studied the forage quality of two grass species growing on coastal wetlands of the Nile Delta. These species are namely: Leptochloa fusca (L.) Kunth and Echinochloa stagnina (Retz) P.Beauv. Thirty-six associated species were recorded in the study area, life form ranging from Therophytes to hemicryptophytes and Phanerophytes. The CCA-biplot ordination revealed that Leptochloa fusca (L.) had an intermediate correlation with Na+ and Ca2+ and strong correlation with K+ and organic matter. The productivity of the studied species increased during the spring and summer. This means that they can cover the summer needs for forage. The pH of the soil varied from 7.14 to 8.25 for the different habitats of study area. The soil electrical conductivity varied from 0.19 to 4.00 ds m-. K⁺ concentration of the soil ranged from 23.59 to 54.11 mg g-1, that of Na⁺ from 2.52 to 4.37 mg g-1, and of Ca²⁺ from 2.88 to 3.99 mg g-1.. For plant L. fusca (L.).E. stagnina, respectively. The chemical characteristics of the shoot samples collected from both the natural grass.

Stagnina About L.Fusca (L.).In general, these ratios are acceptable when using these plants as feed. Compared to international standards. The obtained results of the present study will be useful for the agro-agricultural application of these natural forages in particular in summer season.
