| Abstract | ||||
| A pot experiment was carried out at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shebin El-kom, Egypt during winter growth season of 2015/ 2016 to study the effect of foliar applications of silicon (Si) and micronutrients ( Fe, Mn and Zn ) individually and combined without and with farmyard manure ( FYM ) on barley plant (Hordeum Vulgare L ) irrigated by saline water under sandy soil conditions. Surface soil sample (0-20cm) 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. Farmyard manure was added at a rate of 3% before sowing. Foliar application of silicon was carried as potassium silicate (25% SiO2 + 10% K2O) "F1" where foliar solution of micronutrients of Fe, Zn and Mn mixture (12 % , 12% and 14 % respectively) " F2" in EDTA form. The final volume of foliar solutions was 400 liter /fed. Applications of F1, F2 and F1+F2 were carried out after 35 days of sowing. The obtained data showed that individual and combined applications of F1 and F2 without and with FYM resulted in a significant increases of dry matter yields ( g/pot ) of both roots and shoots of barley plants, where the highest values was resulted with the combined treatment of FYM +F1+F2 followed by that resulted from the treatment of F2 +F2.Also,the high contents and uptake of N, P, K, Fe , Mn , Zn and Si by both roots and shoots of barley plants were resulted from the treatment of F1+F2 with FYM. So, all relative changes ( RC , % ) values of macro- and micronutrients and silicon uptake by barley plants ( roots and shoots ) at age 42 and 70 days were positive . From the obtained data may be concluded that , under sandy soil conditions using saline water for irrigation , organic manures and foliar applications of Fe , Mn , Zn and Si is very important to increase plant growth and decrease the harmful effect of salinity stress . | ||||
