Due to rapid industrial development activities and increasing population, the resources are declining throughout the world. So, there is a need to adopt recycle and reuse strategy. Due to increasing population high volume of wastewater is being produced in the cities. As the sewage water serves as the important source of nutrients and trace elements it can be utilized for the irrigation purpose. Sewage water supplying large amount of nitrogen and phosphorus and their beneficial effect on improving and maintaining good soil structure is well established. The present research was conducted to record the effect of sewage water on growth yield and quality parameter of marigold over a period of year 2020 – 2021 at College of Horticulture, Kolar during rabi season in the pots under polyhouse condition. The experiment laid out in Factorial Randomized Complete Block Design (FRCBD) with 2 factors and 10 treatments with three replications. The standard protocol was followed for recording the observation. It was observed that all the quality parameters viz., highest flower diameter (6.69 cm), maximum number of petals (239.63), maximum shelf life of flowers (4.01 days), flower weight (7.38g) and highest carotene content (25.26 g kg-1) were significantly higher in the plants treated with 100% untreated sewage water (T2).
