Ground water quality plays a key role in sustainable crop production. It is the quality of ground water that decides possibility and choice of crops for a particular area. So characterisation of ground water is necessary to use for agricultural purposes. So ground water quality parameters of Rania block in Sirsa district in Haryana were assessed to have an idea of suitability of tubewell water for irrigation purpose. A total of 180 samples received in soil testing laboratory of Krishi Vigyan Kendra, Sirsa were analysed for pH, EC, cations, anions. Subsequently RSC and SAR were calculated by standard procedures. EC ranged from 0.3 dSm^-1 to 16.0 dSm^-1 with mean values of 3.88 dSm^-1 whereas pH ranged from 4 to 8.6 with a mean value of 7.7. Among the cations Na⁺ was dominant with mean value 27.83 meL^-1 whereas Cl^- was dominant anion. Of all the samples, 31 per cent water samples were in the good category in which almost all the crops could be grown. 36 percent water is saline which should be used in combination with canal water in cyclic mode. 19 per cent water samples were marginally saline, 4 percent water was alkali and there is need to neutralise it with gypsum application. 10 percent of the water samples were marginally alkali which can cause problem in the soils where silt and loam content are more.
