The experiment was conducted in the field on a normal soil. Brackish tube well water was used for irrigating wheat and rice crops without any amendment and with gypsum (equal to sodium contents of irrigation water; and two times its sodium contents). Wheat and rice crops were grown from Rabi 1995-96 to Rabi 1998-99. Grain and paddy yield along with Electrical Conductivity (EC), Sodium Adsorption Ratio (SAR) and pH of the soils were recorded. Use of brackish water without any amendment resulted in an increase in EC and SAR of the soil and caused a decrease in crop yield. Use of the same water in combination with two times its sodium contents resulted in normal yield of both the crops without any harmful effect on the soil. Gypsum equal to sodium contents of the irrigation water proved comparatively less effective.
