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
