In the present study germination, photosynthetic pigments growth and yield in Pisum sativum var. P.Arkel was investigated under salinity stress. Salinity caused by NaCl is an abiotic stress inducing morphological and metabolic disorders. The pot experiment was carried out in department of Botany at Mohammad Ali Jauhar University, Rampur and the plants were exposed to different doses of NaCl and the data was recorded at 65 and 75 days after sowing (DAS). The impact of NaCl concentration (4mmhos/cm, 8mmhos/cm and 12mmhos/cm ) is reported on morphological and physiological traits on Pea . A significant reduction of shoot and root biomass, root nodules, plant length and leaf area affected by salinity was observed in 12 mmhos/cm of NaCl. Higher salinity induces a reduction, a delay and even a complete inhibition of germination caused due to osmotic effect or /and ion toxicity . All growth attributes such as plant length leaf number and leaf area decrease in all the salinity levels. Salt (NaCl) stress through enhancement of osmotic pressure leads to the reduction of germination, growth and effect the yield of the plant. Saline soil induces physiological and metabolic disturbances in plants, effecting growth development, and quality of yield in plants. In general, salt stress decreases the chlorophyll content and carotenoids of plants but increased the level of proline.
