Abstract: Two field experiments were conducted in clay saline soil at the Sahl El-Houssinia Agriculture Research Station, Sharkia Governorate, Egypt. Faba bean cultivar Nubaria 1 planted during winter seasons 2018/2019 and 2019 /2020 to study the effect of different sulfur sources i.e. calcium sulphate (CS), potassium sulphate(KS)and agricultural sulfur (AS) in four rates 0, 200, 400 and 600 kg/fed as control, low rate, medium rate and high rate, respectively with or without farmyard manure on inhibitory the hazardous effect of soil salinity stress on vegetative growth, yield and yield components and some soil chemical properties. Each experiment was carried out in a split split-plot design, where the sulfur sources were arranged randomly as the main plot and the rate of sulfur sources were distributed randomly as subplot and FYM (with or without) was arranged randomly as sub subplot. Yield and yield components, macro and micronutrients content and uptake by faba bean seeds were increased as a result of applied different sulfur sources and rates and/ or FYM and their combinations. Seed protein content, total carbohydrates and total chlorophyll were increased significantly as affected by the treatments. The control treatment (without fertilizers) increased proline content over the treatments. Sulfur treatments decreased values of soil pH and EC and increased soil available N, P, and K as well as Fe, Mn and Zn content after harvest. The superior treatment was observed when using sulfur with FYM, especially at the high rate (600 kg/fed.), which gave the highest values for all variables under study.
