摘要：Irrigation of crops is an essential input for attaining high yields, but the quality of the irrigation water is also equally critical for long term achievable production goals. Poor quality water, if used for a long time will make the soil less productive or even barren depending on the amount and type texture of soil. Low or marginally saline water sometimes appears to stimulate crop growth because of the nutrient ions present. However, the excess of soluble salts in water leads to their accumulation in the surface particularly in heavy textured or in poorly drained soils. Many areas of country are facing a serious problem of not only scarcity of water but also critical poor quality of irrigation water. Tube-well and on well generally pose such problems more than surface water.
