ABSTRACT

The present study is carried out - in the area near river Ganga where water table is lying with in the vicinity of   0.76 to 15.40 meter below ground level (m.b.g.l). The study is carried out to ascertain the suitability of groundwater for irrigation purposes. The parameters used to ascertain the suitability of water for irrigation purposes are synthesized.  The parameters used for the purpose are; electrical conductivity, sodium adsorption ratio, sodium percent, residual sodium carbonate, magnesium ratio, permeability ratio and Kelly’s ratio. U.S. salinity laboratory diagram and Wilcox diagrams were also prepared. 16% of the samples show high electrical conductivity. Rest of the parameter show groundwater is suitable for irrigation purposes save magnesium ratio which shows groundwater may be toxic to plants- so crop susceptible to high magnesium content can be avoided in the area and crops requiring high Mg contentment can be grown in the area. The ionic contribution to the groundwater is not from the atmospheric precipitation but from rock – water interaction – as shown by high Na/Cl and K/Cl ratios.

Keywords: Sodium adsorption ratio, residual sodium carbonate, Kelly’s ratio, magnesium ratio.
