Salinity, levels of soils under study were, 8, 11.6, 14.6, 17.4 and 20.9 dSm⁻¹ . The results showed that increasing soil salinity level caused a significant decrease in sorghum grain yield, harvest index, N-uptake, nitrogen efficiency ratio (NER) and percent N- recovery. However N- concentration ingrains increased with increasing soil salinity level. Meanwhile, grain index was significantly increased with increasing soil salinity level up to 11.6 dSm⁻¹ due to stimulation effect of salinity. Raising N- fertilizer rate up to 100kg/faddan lead to a significant increase of sorghum yield and its components with decreasing (NER) values. Basing on the abovementioned studied characters, ammonium sulphate is considered to be the best N-fertilizer, which can be used under the studied condition UR - http://nile.enal.sci.eg/EALE/2004/ZJAR/3104/4b/1635.pdf ER -
