ABSTRACT
The experiments were performed to test the influence of amendments on the growth of Phaseolus vulgaris L. plants. The amendments tested were natural bentonite, natural zeolite modified with Ca2+ and natural zeolite modified with NH4+, respectively. The seeds of beans were planted in polluted soil mixed with 5% and respectively 10% content of amendment. Mixes with the two above-mentioned concentrations were prepared with each type of amendment considered. Soil without amendment was used as control-soil. In each of the seven experimental series, 15 seeds were planted. The height of each plant was measured and recorded after a pre-established number of days, up to one calendar month. Data were analyzed using version 16.0 (for Windows) ofthe SPSS software package.
