EFFECT OF CHROMIUM COMBINED WITH ATRAZINE ON POTASSIUM, SODIUM, MANGANESE, IRON AND PHOSPHATE IN ROOTS AND SHOOTS IN BEAN Vigna radita (L.) WILCZEK

The effect of chromium combined with atrazine on manganese, sodium, potassium, iron and phosphate uptake was observed by bean plants. In shoot of the plant sodium, potassium and phosphate content got appreciably decrease in comparison the other contents while increasing concentrations of atrazine as well as chromium (10-200 ppm). However in root, all of the contents got increased with enhanced concentrations of chromium (10-200 ppm) at same level of atrazine (10-200 ppm). High level of toxicity was observed at high concentration of atraziine (50-200 ppm) and chromium (50-200 ppm).
