Abstract
The study focuses on the use of Waste Stabilization Ponds (WSP) effluent for irrigation and also aims to compare the efficiency of effluent with the Hoagland solution. Results revealed that the number of flowers, size of flower and the petals per flower increased by the use of both Hoagland solution and treated effluent while the height of plant and the fresh weight of flowers were increased significantly by the Hoagland solution only. Moreover, the leaves showed high concentration of reducing and non-reducing sugars as compared to flowers whereas, only the leaves of plants which were treated by the ponds effluent had low content of reducing sugars as compared to leaves of untreated plants serving as controls. The variation in chlorophyll content was similar to that of reducing and non-reducing sugars. In addition, leaves of plants that were treated by pond’s effluent showed highest concentration of total phenol content. It is concluded that treated effluent is as effective as Hoagland for the irrigation of rose. Additionally, the use of treated effluent for irrigation reduces the demand of fresh water and the use of inorganic fertilizers for the commercial production of roses.
