ABSTRACT
Sublethal atrazine concentration with toxic Cd (cadmium) metal induced, general inhibition on growth, photosynthesis and nutritional level of bean plant. Progressive reduction in protein, amino acid and carbohydrate synthesis were associated with increasing herbicide concentration at all experimental periods. Nodulation failed to occur in roots of leguminous plant. The rhizosphere was found to be affected and colonies of helpful organism were observed in which Rhizobium species were not isolated from the roots. The results of these investigations allowed me to draw a conclusion that soil enriched with heavy metal kill the microbial life. Therefore they cannot degradate the atrazine herbicide, which is highly toxic to photosynthetic processes of the plant and translocated to the tips of leaves. But soil enriched with toxic metal was effected on the microbial life. This causes the lowering of the soil ability in mitigation of the dangerous herbicide activity.
