Measurement of soluble salt content in soil is termed as soil salinity. Both positive and negatively charged ions are contained in such soils and being free can be absorbed by plants. A pot study was performed to assess the poisonous impact of NaCl salinity on rice growth parameters. Selection of soil with customary characteristics was done. Various levels of salinity; < 4, 4, 6, 8, 10, 12 and 14 dS m-1 were established using NaCl salt. Soil was left for appropriate period for accomplishment of salinity. Completely randomized design (CRD) was used for layout of the experiment. Transplantation of seedlings was performed in all pots. Application of mineral fertilizers at recommended rates was done. Crop was grown till maturity and then data gathering concerning yield related parameters was carried out and statistical analysis was performed. It was observed from the results that addition of NaCl proved toxic for growth and yield of rice plants as well as associated parameters such as plant height, number of productive tillers, total biomass, straw and grain yields were negatively influenced by the increasing levels of sodium chloride when compared with control treatment. Injurious impact of NaCl was more pronounced as the concentration of salt increased in the treatments.
