Increased productivity, lower cost
TIRUCHI: Using urine as a liquid fertiliser for raising paddy will have a double-pronged advantage of increasing the productivity and bringing down the cultivation cost in terms of chemical fertilisers, said Head of Department of Soil and Crops, Tamil Nadu Agricultural University, Killikulam, Tirunelveli, C. Ponniah.
Speaking at a function to mark the transplanting of saplings of ADT-39 paddy at a urine fertiliser demonstration plot at Musiri, near here, on Thursday, Dr. Ponniah said that the rich content of three important ingredients – nitrogen, potassium and phosphorous – in urine enhanced the growth of plants. Its nitrogen content in the form of ammonia was most suited for raising the crops.
M. Subburaman, Director, Society for Community Organisation and People’s Education (SCOPE), a Tiruchi-based service organisation, which co-ordinates the project, said that this was the second year in succession that the study had been taken up for raising ADT-39 using urine.
Reeling out the statistics, he said that last year, the per hectare yield of this crop with a duration of 110 days, was 4.625 tonnes against the usual 4.5 tonnes. Dilution of urine with water was a more efficacious fertiliser, bringing down the cost of normal input by at least 25 per cent. Efforts were being taken to conduct similar study on cultivation of banana in co-ordination with the National Research Centre for Banana, Tiruchi.
President of Musiri Special Grade Town Panchayat V. C. Sudhakar gave away the saplings to the agricultural labourers for transplantation.
Liaison Officer, SCOPE, V. Ganapathy, said that about 250 litres of urine for the fields was being collected from three community compost toilets, also constructed by the SCOPE earlier.
