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.
