Irrigation is one of the most important inputs for an efficient and sustainable agricultural production. The evaluation of agricultural suitability is essential for identifying which crops can be cultivated properly in a particular area as well as the methods and practices that must be used to have the maximum production and sustainability. Being an agro-based economy it is necessary to have a good quality of water for irrigation. About 89% India’s groundwater is used for irrigation, 9% for residential use and 2% for irrigation purposes. This study was conducted to evaluate the Irrigation Suitability of Safidon tehsil in Jind District, Haryana. Total 76 samples were collected from the Safidon tehsil. The water samples were analysed for major cations: Na + , Ca 2+ , K + and Mg 2+ . The Irrigational suitability will be calculated by using Sodium Adsorption Ratio (SAR), Magnessium Adsorption Ratio (MAR), Sodium Percent (Na %), Kelley’s Ratio (KR), Electrical Conductivity (EC) and Soluble Sodium Percent (SSP). The values obtained from the study area shows that 96% samples of SAR values came under excellent category and remaining 4% lies under good category, the value of EC lies between 605μS to 5540μS, the values of SSP shows that 64% were suitable and 36% were unsuitable, KR values shows that 64% samples were suitable and 36% were unsuitable and for MAR only 18% samples were suitable and 82% samples were unsuitable for irrigation purposes and these values shows the magnessium hazard in the study area, and Sodium Percent values lie between 17.20 to 79.15%. Key words: Irrigational Suitability, Sodium adsorption ratio, Magnessium Adsorption Ratio, Sodium Percent, Soluble sodium percent, Kelley’s Ratio. Introduction India contributes around 14% of country’s gross domestic product (GDP) in agriculture sector. If the suitability of water for irrigation purposes is good of any region it will result in the maximum crop yield under the water and soil management practices. Now a days farmers using varies type of fertilizers in their fields to have a high crop production which has a negative impact on the water suitability it de- creases the quality of soil. An area-specific water quality index (WQI) must be developed since the quality of water used for ir- rigation purposes varies from region to region and it can be affected by several factors such as plant char- acteristics, soil quality, and climatic and local condi- tions. When evaluating water quality, physical and chemical parameters are important factors to con- sider but analyzing these factors individually doesn’t provide a clear picture of the water quality
