Suitability of Groundwater Quality for Irrigational use between Silkanth and Kundgaon, North of River Narmada in the Upper Alluvial Plains of Narmada Valley, District Sehore and Dewas, M.P., India

Groundwater is one of the earth’s most widely distributed resources and is consistently catering to the requirement of the agricultural irrigation. In the present study, an attempt has been made to understand the hydrochemistry and its agricultural water quality of groundwater between Silkhanth and Kundgaon, North of river Narmada, Madhya Pradesh. During the course of water quality studies of the area,17 groundwater samples were collected and chemically analysed. Results obtained from water chemistry were used in the determination of different irrigational specifications to appraise the agricultural quality of groundwater. Important specifications like Sodium Adsorption Ratio (SAR) Residual Sodium Carbonate (RSC), Soluble Sodium Percentage (SSP) and Kelly’s Ratio (KR) are used for decisive the appropriateness of groundwater for the agricultural purposes. Result shows that the majority of groundwater belongs to Medium to -High Saline and Low sodium water. As per the magnesium ratio classification, the ground waters of the study area has no magnesium hazards. Kelly’s ratio shows that majority of groundwater belongs to suitable class. As per the classification based on RSC the groundwater belongs to Safe class. As per the guidelines of Ayers and Westcot, majority of water have slight to moderate toxicity with respect to Nitrate and their use is restricted for semitolerant crops.
