A field experiment was conducted in the experimental station, Fac. Agric., Mansoura Univ., Egypt, on rice crop (Oryza sativa L.) to evaluate the ability of soil degradation resist as a result of low water quality and farmyard manure application. The experiment involved nine treatments, three irrigation waters quality (tap water, saline sodic water and saline water) and three rates of farmyard manure (0, 5 and 10 ton fed^-1). The experiment was designed in split plot design. The results illustrated that the highest fresh and dry weight was recorded with the soil ‎irrigated by tap water followed by saline water and amended ‎with ‎FYM rates 10 and 5 ton fed^-1. These results may be attributed to the ‎increase in soil physical properties i.e. saturated ‎hydraulic ‎conductivity (Ks), mean pore ‎diameter (MPD), bulk density (BD) and pore size ‎distribution (PSD). Furthermore, the addition of ‎FYM ‎increased the ‎soil content of organic carbon (SOC) which considered the main ‎‎reason ‎in improving the soil physical properties in combination with the good ‎chemical ‎‎composition of irrigation water (Ca⁺² more than Na⁺).‎
