p.1001-1016. Apot experiment was carried out in the farm of Fac. of Agric. Mansoura University during the winter cultivation of 2010 and 2011 to investigate the impact of minimizing levels effect of salinity for spinach plant (Spinacia Oleracea) by using some organic materials. Thirty treatments were arranged in split-split block design, which three treatments of salinity levels, S1 (2.55), S2 (4.79), and S3 (6.39) ds/m in 1:5 soil water extraction were assigned to the main plots. Five treatments of organic materials, i.e; farmyard manure (F.Y.M.), chicken manure (Ch.M.),compost of rice straw, wood saw dust (W.S.) and the untreated treatments (control)were allocated in the sub-plots. Each treatment was investigated twice; one was sprayed with ascorbic acid and the other without spraying it and arranged in sub-sub plots. Thus, the total numbers of pots were 90 pots. The results of this investigation revealed that; with increasing salinity levels, the mean values of fresh and dry weights (g) of spinach plant leaves,roots and the mean values of N, P&K uptake (mg/plant) of spinach plant leaves and roots.AlsoCa, Mg & Na uptakes (mg/plant) ofroots were decreased. On the other hand, the mean values of Ca, Mg and Na uptakes (mg/plant) of spinachleaves were increased with increasing salinity levels. Keywords: Salinity levels, organic materials, ascorbic acid and spinach plants. Includes references. Summary in Arabic.
