INFLUENCE OF AMENDMENTS OF WASTE WATER OF NOOR MOHAMMAD KUNTA ON GROWTH OF MARIGOLD (Tagetus erecta L.)

Abstract

Noor Mohammad Kunta, a lake located on NH-7 in Rajendranagar municipality adjoining Hyderabad city has water spread of 27 acres and an independent catchment area of 175 hectares. It flows down to Shivarampally lake then to Voora cheruvu and ultimately to Mir Alam tank. The industrial effluents of the Katedan industrial area contaminate the water of Noor Mohammad Kunta Lake at Rajendranagar. Use of such waste waters for agricultural irrigation purpose can lead to accumulation of heavy metals in the crop produce, thus entering into the food chain and thereby posing threat to human and animal health.
