The proximate composition and sugar content of edible parts of the vegetables grown under sewage and fresh water  irrigation  were  assessed in the  present study. Sewage and fresh water irrigated vegetables such as brinjal, coriander leaves, methi leaves, palak and tomato were collected   from the farmers of   Giriyal and   Gamanagatti   villages of  Hubli taluk respectively. The results of the proximate analysis showed that the moisture, protein, fat, ash, crude fiber, carbohydrate and sugar contents of vegetables were significantly influenced by quality of irrigated water. The mean moisture content was significantly lower in sewage water irrigated vegetables. Whereas the mean protein, fat, ash, crude fibre   and sugar contents were higher in sewage water irrigated vegetables. Significant difference was observed between the vegetables irrespective of irrigation source. The highest moisture, total sugar, reducing and non reducing sugars were found in tomato followed by brinjal. The highest protein, fat, ash and crude fibre contents were observed in coriander leaves. Overall the nutritional values of vegetables irrigated with sewage water were higher than those irrigated with fresh water.
