Impact of municipal and industrial waste water on corn (Zea mays L.) cultivars

The impact of municipal and industrial waste water was studied on seed germination and seedling growth of different corn cultivars (viz. 31Y45,Shakti-1 and Siddhi). The experiment was formulated with four treatments (i.e. 25%, 50%, 75% and 100%) of waste water with three replicates each. Tap water was taken as control.The seed germination and seedling growth were inhibited in treated sets and this inhibitory effect increases with increased in the concentration of treatment. At lower concentration i.e. at 25% of wastewater, however, some promotion in seedling was recorded. Cultivar specific and organ specific differences often exists. Thus, waste water after proper dilution may be used for irrigation of crops
