Growth and yield of two Tunisian pepper varieties were evaluated for their salt and water stress tolerance under the salinity levels of 0, 30 and 60 mM NaCl and water stress with 50% depletion of available soil water. The treatment were applied 10 days after transplanting and continued up to plant harvesting. The results of this study indicated that growth, leaf area, yield and marketable fruits of the pepper genotypes were clearly decreased when the plants were exposed to water stress, salt stress and, combined salt and water stress conditions. Reduction is more noticeable in 60 mM NaCl salinity combined with water stress.

Abstract
Growth and yield of two Tunisian pepper varieties were evaluated for their salt and water stress tolerance under the salinity levels of 0, 30 and 60 mM NaCl and water stress with 50% depletion of available soil water. The treatment were applied 10 days after transplanting and continued up to plant harvesting. The results of this study indicated that growth, leaf area, yield and marketable fruits of the pepper genotypes were clearly decreased when the plants were exposed to water stress, salt stress and, combined salt and water stress conditions. Reduction is more noticeable in 60 mM NaCl salinity combined with water stress.
