A STUDY was conducted on a village 4, Gilbana town at Sahl El-Tina plain, North Sinai, Egypt during two successive winter seasons of 2011/2012 and 2012/2013, in order to investigate the influence of sulphur from different sources, i.e., gypsum (G) in two rates G1 and G2 , 4 Mega gram (Mg) fed-1 and 8 Mg fed-1, respectively as well as elemental sulphur (ES) and sulphuric acid (SA) as soil application on inhibitory the hazardous effects of soil salinity stress on vegetative growth, yield and its quality of new cultivar Masr 2 of wheat (Triticum aestivum cv.) grown on a salt affected soil irrigated with low quality water of El-Salam canal as well as some chemical characteristics of the experiment soil after harvest. The obtained results could be summarized as follows:
- The highest values of wheat yield and its attributes, as well as grains quality, was obtained under the treatment of sulphuric acid. Also, the highest nutrient content and uptake by wheat plants were obtained due to the same treatment. - The effective of treatments showed a descending increase in the order of, sulphuric acid > elemental sulphur > gypsum, 8.0 Mg fed-1 > gypsum 4.0 Mg fed-1 > control. - Proline content gave the highest value (18.4 μmol g-1) under the treatment of gypsum at the rate of 4.0 Mg fed-1 in a descending order; gypsum, 4.0 Mg fed-1 > gypsum, 8.0 Mg fed-1 > elemental sulphur > sulphuric acid > control. - Soil available N, P and K were increased due to the application of different treatments over the control. The corresponding highest N and K values were 55.1 and 202 mg kg-1 soil, respectively and recorded under application of sulphuric acid while it was 4.75 mg P kg-1 soil due to the treatment of 8 Mg gypsum fed-1. The highest values of Fe, Mn and Zn (2.92, 2.41 and 0.85 mg kg-1 soil, respectively) were obtained due to sulphuric acid treatment. Soil pH and soil EC were decreased due to the application of the treatments comparing to the control. The lowest soil pH and EC values (7.98 and 7.53 dS m-1, respectively) were obtained under sulphuric acid treatment.
