Résumé
The current study was carried out as a pot experiment at the Experimental Farm of Faculty of Agriculture, Menoufia University during winter growth season of 2015 -2016 to study the individual and combined effect of inorganic and organic fertilizations and Si application on barley plant irrigated by saline water under sandy soil conditions as well as sandy soil chemical properties and its content of available macro- and micronutrients and silicon . The Experiment Surface soil sample (0-20) cm representing sandy soil was collected from a private farm at 60 km North Cairo and far about one km east of Cairo - Alexandria Desert high away. The collected soil sample was air dried , ground , good mixed and sieved through a 2 mm sieve. Some physical and chemical properties and its content of available nutrients and silicon of this soil were determined. The used organic manure ( FYM) was obtained from the animal breeding farm , Faculty of Agriculture , Menoufia University , Shibin El- Kom , Menoufia Governorate, Egypt. This organic manures were chemically analyzed. A 168 plastic pots with 25 cm inter diameter and 20 cm depth were used in This experiment . Five kg of the sieved sandy soil was put in each pot . The used pots were divided into two main group ( 84 pots/ group ). The soil in the first main group no received FYM but the second one treated by FYM at rate of 3% (150g / pot) . Before planting ,the treatments of FYM and P were carried out and good mixed with the petted sandy soil. The pots of each main group were divided into 14 sub group ( 6 pot / sub group ) .These sub groups represent 14 treatment which may be listed as follows : Without mineral treatment ,treatment of nitrogen (N) fertilizer ,treatment of phosphorus (P) fertilizer ,foliar treatment of potassium (K) and silicon mixture (F1), foliar treatment of iron (Fe) zinc (Zn) and manganese (Mn) mixture ( F2), treatment of N+P, treatment of N+F1, treatment of N+F2 , treatment P+F1, treatment P+F2, treatment F1+F2, treatment N+P+F1,treatment N+P+F2 and treatment N+P+F1+F2. Each treatment was carried out in 6 replicates.Ten seeds of barley plants were sowed in each pot ( Hordeum Vulgare L) at 13 November 2015 in depth of 1 cm. All pots were irrigated by the studied saline water at 60% of WHC and repeated every three days. The studied saline water was chemically analyzed. After 42 days of sowing , the plants of three replicates of each treatment were harvest above the soil surface . The plants in the other three replicates of each treatment were harvested after 70 days of sowing. Directly, the harvested plants of each pot were divided into roots and shoots which harvested after 70 day , air dried , oven– dried at 70o for 48hrs , weighted to obtain the dry matter yield , ground and kept for chemical determinations. After plant harvesting , soil sample of each experimental unit was taken , air –dried , ground , sieved through a 2mm sieve and kept for some chemical properties and the content of available macro- and micronutrients and silicon.
