The effect of salt stress оn some physiological and biochemical parameters in pigeon pea (Cajanus cajan) was studied under controlled conditions. The plants were treated with the solutions of 50 mM NaCl, 100 mM NaCl. It was established that the applied doses of both salt concentrations caused stress on the young pigeon pea plants, which found expression in the suppression of growth, and produced changes in photosynthetic pigments, relative water content, biochemical parameters suchas total soluble sugar, total free aminoacids, total protein, nitrate, antioxidants suchas catalase, peroxidase and superoxide dismutase and stress parameters proline and MDA.
