The ever increasing population imposes continuous pressure on limited water resources. Treated wastewater appears to be a visible and viable option as other sources are windling. In the present study treated tannery effluent mixed with domestic wastewater was used as irrigation source as it provides valuable nutrients. Germination studies and pot culture studies were conducted to assess the impact of treated tannery effluent, mixed with domestic wastewater on the growth of flower crops viz., Calendula offcinalis, Cosmos bipinnatus, Dahlia apiculata, Belli perennis, Dianthus alpines, Hibbertia humifusa, Gomphrena globosa and Tagetes erecta. Highest germination percentage (96%) as well as vigour index (1872) was observed with 25 % treated tannery effluent mixed with 75% domestic wastewater irrigation when compared to other mixing ratios.
