Use of saline-sodic water for crop production

Waters of different salinity and sodicity levels, both unamended and amended with gypsum and choline chloride, were compared with canal water for their effect on the growth of maize and properties of a garden loam soil. The low salinity water (mixture of tube-well and canal water), when amended by passing through gypsum stone or by addition of choline chloride, gave maize crop yields comparable to those obtained with canal water and had no adverse effect on soil properties. Green matter yield had a negative correlation (r=-0.79**) with soil ESP values
