Three systems of irrigation water quality assessment are evaluated in terms of the ratings obtained for 50' irrigation water samples of Delhi villages. It is shown that the U.S.D.A. rating system has limited applicability to Indian conditions whereas the other two methods proposed by Kanwar and Ramamoorthy have wider scope of applicability and agree very well with the field performance of irrigated crops.
