New strategies for plant adaptation with soil affected by salinity are needed. Recent studies on different crops introduced biochar as a promising soil amendment that ameliorate problems associated with salinity stress. Here the study proof that biochar helps seedlings of Volkamer lemon (C. volkameriana, Tenx pasq.) copping with salt stress. Uniform three months old seedlings were transferred in a mixture media consists of sand: peat moss: biochar, 4: 2: 0.5 or 1 v/v, respectively. The plants were subjected to 0, 100 and 200 mM NaCl. The performance were determined by growths related to fresh (F.W)and dry mass (D.W), leaf area, shoot and root length, shoot diameter and root width, shoot/root and water content. Electrical conductivity (EC), Relative chlorophyll content (RCC) and proline content as biochemical parameters were measured. The elements of N, P, K+, Na+ and K+/Na+ ratio were looked up. The results indicated that biochar decreased the salinity effect on plant performance. Plants grown under salt stress in a mixture media contained biochar showed higher content of chlorophyll, N, P and K+ but showed lower content of shoot/root, K+/Na+, proline, EC and Na+ than those grown in the media free of biochar. These results supported the views that introduce biochar as a promising application in mitigating the negative effects of salinity stress on volkamer lemon seedlings.
