Abstract: The use of thermal power plant wastewater (TPPW) and coal fly ash in agriculture for irrigation need specific studies to evaluate their effect on different soils, crops and agro-climatic conditions. This study was therefore conducted to observe the suitability of wastewater for irrigation, and Cicer arietinum L.cv. BG-256was used as a test crop. The experiment was conducted in the winter season of 2000–2001 to evaluate its effect together with the basal application of four doses of nitrogen (N0, N10, N20, N30 kg ha−1). Fly ash (@ 10%) selected from previous study, conducted in the year 1999 was amended with soil to make the final weight 7 Kg ha-1. Wastewater irrigation resulted in the increased growth and yield of the crop. Lower fertilizer dose of nitrogen @ 10 Kg ha−1 together with wastewaterirrigation and fly ash amended soil (FA10) proved optimum, resulting in greater leaf area, plant fresh weight, dry matter (DM) and leaf NPK content, number of pods per plant, 100 seed weight and protein content relative to control which is found to be at par with higher N doses (N20 and N30). Thus fertilizer rates could be lowered without reducing yields when using wastewater for irrigation and fly ash (FA10) as an amendment to the soil
