the increasing number of cases of soil contamination by trace elements have affected crop production, and represents a risk threatening the quality of our food products. Some of these contaminants, such as trivalent chromium Cr (NO<sub>3</sub>)<sub>3,</sub> which is similar to micronutrients, can, therefore, be absorbed by plants and whose phytotoxicity has long been considered negligible, and largely underestimated. The purpose of this work was to study the transfer of trivalent chromium from nutrient solution to green beans <em>Phaseolus vulgaris L</em> grown on bioponics; the contamination responses were determined in terms of growth parameters, yield, and dry matter production; at various concentrations (5, 10 and 20 ppm). Chromium trivalent effects have also been studied in tissues plant. Results showed that the absorption of trivalent chromium from the nutrient solution and its translocation to the aerial tissues plants had no adverse effects on growth parameters, and also on beans yield. Results also showed that chromium accumulates in roots rather than in the other tissues, and did not reduce the dry matter production, in terms of translocation and bioconcentration. The transfer factor is low and green beans cannot be defined as a hyperaccumulator of chromium.
