Abstract: Effect of irrigation with wastewater (Treated and Untreated) from Sargasan and
Jaspur STP plant station on wheat crop as enrichment factor of nutrients in soil
and wheat plant in Gandhinagar district, Gujarat was selected. The sampling was
divided in four phases –I (STP outlet), II (Agricultural fields irrigated with three
sources of water), III (irrigated Soil with three sources) and IV (Crop parameter
analysis). The use of wastewater is seen in eight villages of Gandhinagar district
that included- Sargasan, Adalaj, Tarapur near Sargasan STP plant and other five
villages as Jaspur, Sabaspur, Karoli, Moti Bhoyan and Ishwarpura. The analysis
of results have been analysed on the basis of water quality parameter of
agricultural fields showing treated wastewater quality equivalent to the
groundwater quality when compared with irrigation water quality standards. The
effects of untreated and treated wastewaters and groundwater irrigation on soil
was analysed by nutrient analysis in soil. Great changes in soil properties due to
USW and TSW were observed. Lastly, mineral content of wheat crop was
analysed which showed very less uptake of nutrients from soil due to
environmental factor and chemical composition of soil.
Keywords- STP, Sewage, untreated, treated, wheat, groundwater, soil.
