Abstract
Research was carried out on 0.4 ha field of nonsaline non-sodic loam soil involving four water salinity levels of 736,1056, 1408 and 2000 ppm IDS with wheatrice crop rotation. There was significant increase in the infiltration rate of soil from 1979-80 to 1982-83 in at) the treatments. Hundred percent increase in the infiltration rate was observed where water of 736 ppm TDS salinity was used and this increase reduced to S6.7, 50.0 and 35.5% where waters of 1056, 1408 and 2000 ppm TDS salinity were used. On an average the ECe of soil was significantly decreased from 3.13 to 1.13 and 2.96 to 1.27 mmhos/cm in 0-15 and 0-30cm soil depths respectively during the same period of time. No significant effect of water salinity levels on the SAR. of soil was observed. There was no significant effect of water salinity levels on the yield of wheat and rice, however, the yearly differences were significant, There w« 7, 5, 13 percent decrease in wheat and 8,11 and 17% decrease in paddy yield with the increase of water salinity levels from 736 ppm, TDS to 1056,1408 and 2000 ppm, TDS respectively.
