Irrigation is the science of artificial application of water to the land in accordance with the crop requirements throughout the crop period for the full nourishment of the crops. The water resources for irrigation can be divided into two types, 1.Surface water, 2.Ground water. The ground water is twice as efficient in terms of agricultural productivity as surface water. While using ground water resources for irrigation, a thorough knowledge of its chemistry to assess its quality is essential. This could be very useful for a sound agricultural planning, soil and water management. The main criterion that is usually considered in the evaluation of irrigation is total dissolved salts and Sodium content in relation to the other cations. To study this, Ground waters from 10 bore wells in Andhra Pradesh were collected and analyzed for Sodium, Potassium, Carbonates, Bi-carbonates and Chlorides. The analysis is based on Electrical Conductivity (E.C), Total Dissolved Salts (TDS) and pH of the water. Based on Electrical Conductivity, and Total dissolved salts, 90% samples found to be suitable for irrigation.
