| Abstract: A field experiment was conducted in Al-musayeb project during 2012/2013. Split plot design was used with two factors. The first was irrigation water salinity in which three levels 1.1, 4.2, 8.2 dsm-1 were used. The second factor was sewage sludge applications in which four levels (0, 20, 40, 80 ton.hec-1) were used. There were 12 treatment combinations replicated three times. The results showed that All plant growth parameters such as plant height, dry matter, grain yield, 1000 seeds weight, no. of spikes per square meter, chlorophyll content in leaves were decreased with increasing irrigation water salinity while they were increased with increasing sewage sludge levels. The additions of sewage sludge to the soil reduce the harmful effects of saline water on plant growth and some soil charateristics. | ||
