Use of wastewater for a variety of purposes is gaining increased popularity as a means of preserving scarce freshwater resources and nutrient recycling particularly in developing countries A field experiment was carried out to evaluate the growth and yield of Capsicum annum var. Nishat-1 under irrigation with different concentrations of domestic wastewater (grey and black water) in combination with recommended dose of fertilizers(RDF). This field experiment was carried out for two consecutive years Kharief 2012-2013 and involved 6 treatments (T1–T6) with three replications in RCBD. Before being utilized, wastewater was stabilized for 20-25 days in open containers. The highest yield (288.12 q ha-1 ) was recorded in T1 (Recommended dose of fertilizers =RDF) followed by 283.49 q ha-1 in T4 (50% grey water and 50% RDF ), 275.92 q ha-1 in T5 (50% black water 50% RDF) , 270.03 q ha-1 in T2 (100% grey water), 260 q ha-1 in T6 (50% black water and 50% grey water) and least of 251.96 q ha-1 in T3 (100% black water) . The data also reveals that the concentrations of the various physico-chemical parameters (viz., pH, EC, OC, N, P, K, Ca, Mg, Cu, Fe, Mn, Zn, Cd, Ni, Cr, Pb) of waste water and pre and post experiment soil samples were within permissible limits. Quality parameters viz total soluble salts, ascorbic acid, chl-a, chl-b, total-chl, carbohydrates and protein content between various treatments exhibited different trends. This study shows that there is an option for recycling of stabilized waste water in agriculture.
