Abstract
The use of sewage water for commercial crop like potato (Solanum tuberosum) has gained importance throughout India due to limited water resources, high cost of fertilizers and expensive technology for the treatment of waste water. The present investigation was conducted to analyze the physico-chemical characteristics of sewage water and its effects on parameters of soil and S. tuberosum. Certified seed tubers of potato, S. tuberosum Linn. var. Kufri Chandramukhi (Solanaceae), sown in three sets of pots, were treated with different fertilizer doses of N, P and K (0,50 and 100%) and 0, 25, 50, 75 and 100% sewage water concentrations to study morphological and biochemical parameters. The analysis of sewage water and soil revealed that these were rich in major nutrients. The effects on growth, morphology and yield using 50% sewage water with 50% recommended fertilizer (N, P and K) dose gave the best results in all the cases. Therefore, the combination can be used for commercial potato crop irrespective of the effects of heavy metals present in sewage water on potato crop.

Key words.Sewage water, Solanum tuberosum, Physico-chemical analysis, Soil parameters.
