英文摘要	Eight on-farm trials were conducted during 2008-2011 to investigate the effect of various levels of gypsum application (100, 50, 25 and 0 % of GR) on soil properties and yield of wheat grown on Typic Haplocambids soils irrigated with high residual sodium carbonate (RSC) water. Gypsum requirement (GR) was calculated on the basis of soil gypsum requirement plus quantity of gypsum required to neutralize RSC of irrigation water in excess of 3 me/l. The present study indicated that gypsum application at the rate of 100 % GR decreased soil pH by 0.3-1.0 units and SAR by 10.9-13.1 over control at 0-15 cm soil depth. The grain yield of wheat increased by 600-1700 kg/ha with the gypsum application at the rate of 100 % GR.
