Abstract: This study evaluated fertilizer contribution of municipal wastewater on potato (Solanum tuberosum L.) cultivation in a split-plot experiment having two factors: water quality with 5 levels and fertilizer with 2 levels. Irrigation by raw wastewater supplied 16, 13, 13, 23, 1.7 and 83% of nitrogen (N), phosphorus (P), potassium (K), sulphur (S), zinc (Zn) and boron (B) requirement of potato, respectively. Wastewater,Wastewater compared to freshwater, improved plant height, vigority, area coverage, leaf area index (LAI), stem per plant, number and weight of tuber per plant, above-ground dry matter (ADM) and tuber yield of potato. On average over three years, irrigation by 75 and 100% (raw) wastewater recommendedwith recommended standard fertilizers produced the maximum, but identical, tuber yield. Wastewater raised N, P and K contents in potato plants and tubers. Irrigation by wastewater could save 10-15% fertilizer requirement of potato. It however caused high accumulation of total coliform (TC) and faecal coliform (FC) on potato skin, with a restriction of using the produce.
