Wastewater can be utilized in a variety of ways like irrigation of agricultural land, landscape, aquaculture, urban, industrial, recreational use and also for groundwater recharge. The major objective of wastewater use in agriculture is to optimize its benefits in terms of fertigation i.e., irrigation and nutrient supply with which it is loaded. In the present study, an experiment was carried out to assess the growth performance of Solanum melongena L. (Local Long) 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 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 study shows 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 are within permissible limits. The highest yield of brinjal (330.04 q ha-1 ) was recorded in T1 (Recommended dose of fertilizers =RDF) followed by 299.59 q ha-1 (T5=50% black water and 50% RDF ), 287.69 q ha-1 (T4: 50% grey water and 50%RDF), 280.62 q ha-1 (T6: 50% black water and 50% grey water), 273.48 q ha-1 (T2: 100% grey water) and least of 266.33 q ha-1 in T3 (100% black water). Quality parameters viz., TSS, ascorbic acid, Chl-a, Chl-b, total-chl, carbohydrates and protein content between various treatments exhibited different trends. This study urges upon the averment that irrigation with stabilized grey and black water does not have any adverse effects on the soil chemistry and thus there is an option for recycling of wastewater in agriculture
