ABSTRACT Wheat plays a crucial part in providing food and nutritional security, but rapidly increasing soil and water salinity pose a severe danger to its production throughout the world. Salinity has a direct impact on soil productivity and limits global yield potential. It also has a deleterious impact on wheat growth and development, resulting in lower grain production and quality. Wheat plants use a variety of physiological, biochemical, and molecular mechanisms to adapt to salt stress at the cell, tissue, and whole plant levels to optimize growth and yield while mitigating the harmful impacts of the saline environment. To examine the effect of different salinity stress, an experiment was carried out at Institute of Graduate Studies and Research department of Plant sciences and technologies, Cyprus International University. In present experiment, wheat varieties i.e., V1, V2, V3 was tested under EC control, 7.5 dSm-1 , 10 dSm-1 , and 12 dS m-1 following Completely Randomized Design (CRD) with factorial arrangement. The findings revealed that as saline levels increased, wheat growth and yield characteristics decreased dramatically. Among V1, V2, and V3 highest reduction in plant height, SFW, SDW, RFW, RDW, number of tillers, spike length and grain yield were noted in V3 when treated with 12 dSm-1 . Furthermore, V1 performed best as compared to all other varieties. Keywords: Salinity, Wheat, Antioxidants, Growth, Yield
