Abstract
Field experiment was carried out at the Experimental Research Station (Abis), Faculty of Agriculture, Saba Basha, Alexandria University, during the growth season of 2013/2014 to investigate the effect of sulfur and silicon applications on the yield and chemical composition of Maize (Zea mays L.)plant grownunder saline soil conditions. The seed individual hybrid 352 cultivar was used in this study. Two factors were conducted in a split-plot design with three replications. The elemental sulphur was applied to the main plots before planting at rates of 0, 200, 400 and 600 kg S/ fed. The sub- plot contained silicon treatments which were added before planting at rates of 0, 5, 10 and 15 kg Si/fed as potassium silicate. The highest grain yield of maize (1.472 ton/fed) was obtained due to application of 600 kg S/fed. Applied potassium silicate in combination with sulphur levels increased the grain yield in comparison with the control. Nitrogen, P, K, S and Si contents in leaves of maize were significantly increased as sulphur rates increased. Also, silicon application increased N, P, K, S and Si contents in leaves of maize at harvest as compared to the control. Nitrogen concentration and protein content in the grains of maize significantly increased as sulphur or silicon rate increased. Also, the application of sulphur or silicon and their interaction had significant increase effect on the amount of available S and available Si in soil.
