Wheat cv. WL 711 grown at Bichpuri, Uttar Pradesh in the 1985-86 harvest years was irrigated 2, 4 or 6 times with the best available water (2.2 dS/m) or with saline water (6 or 12 dS/m). Mean grain yield was 2.6, 3.9 and 4.1 t/ha with 2, 4 or 6 irrigations, respectively, and 4.0, 4.2 and 2.7 t/ha when irrigated with water of 2.2, 6.0 and 12.0 dS/m. Water use efficiency decreased with increasing number of irrigations and was lowest when irrigated with the most saline water. Soil salinity increased with increasing irrigation frequency and with increasing salinity of the irrigation water.
