Abstract: Salinity is a constraint in many field perimeters. Thus, the search for plants adapted to high salinity thresholds becomes an imperative for agricultural production. This accumulation of salts in the soil reduces the yield of crops and mainly the food crops of which the tomato belongs. The objective is to use a chemometric approach using different statistical techniques to evaluate the effect of NaCl concentration on the agrophysiological and biochemical parameters of three varieties of tomato. In order to carry out this study, the experimental setup in complete random blocks with three repetitions was used. During the experiment, concentrations of NaCl 0 g / L, 2 g / L, 4g / L and 6g / L prepared were applied one week after transplanting three tomato varieties (Petomech, UC82 B and Tropimech) periodically (every two days) to agrophysiological and biochemical data. The results of the analysis showed that, in addition to the concentration of NaCl 2g / L, the mean values of the biochemical parameters varied significantly, resulting in differences between the three varieties of tomato. Further studies extended to mineral and organic elements will allow to better understand the level of the effect of NaCl on all the agronomic and biochemical parameters
