The newly reclaimed soils suffer from some stresses, especially salinity, whether in the soil or irrigation water that severely hinder the growth and production of some crops. A pot experiment was conducted during 2021 and 2022 seasons at Al-Marashda Research Station, Qena, ARC, Egypt to study the influence of silicon and endophytic fungi on germination percentage, survival seedlings rate, biomass and chemical traits of Moringa oleifera under salinity conditions. Pots were filled with sandy soil as substrate and arranged in completely randomized design, having nine treatments, including silicon and endophytic fungi together or alone with two levels of salinity. The two salinity levels were significantly affected the germination and survival percentages, biomass as well as chemical compositions of M. oleifera. However, addition of silicon at 100 mg/ l or endophytic fungus (Chaetomium globosum) at 100 ml, together or alone led to increase germination percentage and survival rate, biomass characters, N, P, K, and total chlorophyll in moringa leaves under saline conditions. The improvement was better with lower salinity level (3 dS m^-1) compared to the higher one for the 1^st and 2^nd seasons. Application of both silicon and endophytic fungi led to better growth results compared to the individual treatments. Leaves of salt- treated plants without any additives contained high levels of Na⁺ and Cl^- compared to those treated with saline reducers.
