Abstract
The waters containing chromium (Cr) mainly from industries enter into the sewers, municipal treatment plant, streams and lakes that are used for irrigation purposes. The effect of Cr in irrigation water on seed germination and growth of French bean (Dolichos lablab L.) was investigated. Germination studies were conducted in the lab and field conditions. Seeds were treated with different concentrations (0 to 25 mg/1) of Cr in irrigation water. The percentage germination of seeds and plant growth showed a gradual decrease with increase in Cr concentration. Stimulatory effect in growth of plant was observed at lower concentration (1 to 2 mg/l). Accumulation of Cr was in the order of Root > Leaf > Stem > Pod. There was an increase in the total concentration of Cr content of soil with increase in Cr concentration in irrigation water.
