Abstract
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 (SpinaciaOleracea) 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 investigatedtwice; 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,rootsand 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.
Data also indicated that under addition of organic materials, all parameters under investigation were significantly increased.The highest mean values of fresh and dry weights (g) of spinach leaves and roots and the highest mean values of N, P &K uptakes (mg/plant) of spinach foliage and roots were recorded with adding chicken manure, however the highest mean values of Ca, Mg and Na uptakes (mg/plant) of spinach foliage and roots were realized with adding wood saw dust.
Concerning the effect of ascorbic acid as foliar application at rate of 400 ppm, it wasfound that all parameters under investigation significantly increased except the mean values Ca, Mg & Na uptakes (mg/plant) of spinach rootswhich were significantly decreased.
