A field experiment was in Sahl El-Tina site, North Sinai Governorate, during the two successive seasons (2015/16 and 2016/17) to study the of applying some soil amendments (sulphur (S) (0.5 Mg fed-1), gypsum (G) (2 Mg fed-1), compost (C) (5 Mg fed-1) and their combinations, (S+G), (G+C), (S+C) and (S + G and C), comparing with control) in salt affected soil on soil properties, forage yield and quality of fodder beet variety, A randomized complete block design with three replications was applied.Application of soil amendments weresignificantly edsoil EC values in case of the first and second growing seasons. Whereas, the soil pH was significantly decreased by applying all amendments compared to control. The concentrations of N, P and K in fodder plants illustrate a relative increase by decreasing soil salinity as a result of was adding different amendments.The results showed that soil amendment application increased top and root fresh yield, dry matter yield, crude protein content, root length and diameter, while values of Nutrient Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) Generally fodder beet top had higher contents of crude protein, crude fiber and ash than roots and the reverse was true for organic matter and nitrogen free extract contents. The percentage of Total Digestive Nutrients percentage (TDN), Relative Feeding Value (RFV) and Relative Forage Quality (RFQ) overall the studied treatments had a prime performance as a superior intake.
