Soil is a valuable resource with a key productive r ole in agriculture. Abiotic stress is the most harmful factor concerning the growth and productivi ty of crops worldwide. Physiologically and genetically salt tolerance is complex among the var iety of plants with a wide range of adaptations in halophytes and less tolerant plants. Present investigation was carried out to study the effect of NaCl salinity on photosynthetic pigme nts and polyphenols of the leaves of Cymbopogon nardus (L.) Rendle. It is observed that the total chlorophyll content of the mature leaves was increased considerably due to increasing concentrations of NaCl upto 200 mM in Cymbopogon nardus. Maximum increase in carotenoid c ontent was observed as 6.05% (50 mM) in Cymbopogon nardus. Polyphenol content was increa sed upto 300 mM NaCl concentration and showed a perfect positive correlation with the increasing levels of salinity stress. The details of results obtained are discussed in the present pa per.
