Abstract

Using moist sewage sludge as a new source for growing rice is an alternative community wastewater treatment with agricultural benefit and ease management (saves time and space). The experimental study was conducted to investigate the potential of using the moist sludge from community wastewater treatment in growing rice (Oryza sativa L.-Chinat1 rice cultivar). In this experiment, the sludge was divided into 21 treatments, which could be categorized by the level of piling depth and the sun drying time. The sludge was piled at the depth of 10 cm (H10), 20 cm (H20) and 30 cm (H30). For sun drying of moist sludge, the sun exposure time was varied from 0-18 days, 0 day (D0), 3 days (D3), 6 days (D6), 9 days (D9), 12 days (D12), 15 days (D15) and 18 days (D18). The results showed that moist sewage sludge piled at the depth of 30 cm can be used to grow rice (Oryaza sativa L) under the present set of experimental conditions with sufficient nitrogen.
