Effect of Salinity of Irrigation Water and Soil Leaching on Wheat YieldAbstractSalinity of soil and water resources is one of the most important problems which reduceagricultural production and gradually decrease the area under cultivations One of theeffective methods of reducing the salinity hazard is the application of leaching andleaching management In this study the effect of three irrigation water qualities of 4 9and 12 dS m and four leaching levels of 0 17 29 and 37 percent in a silty clay loam soilon wheat yield and some chemical characteristics of soil and drainage water wasinvestigated The study was carried out in a greenhouse at Isfahan University ofTechnology in completely randomized design as factorial with 7 replications The resultsshowed that soil salinity sodium adsorption ratio and exchangeable sodium percentincrease with increasing in salinity of irrigation water and increase as leaching leveldecreases and these values are greater for soil depth of 0 15 cm as compared to soil depthof 15 30 cm The increase of leaching level increases soil acidity and soil acidity in thelower layer was greater than the top layer but the changes were not significant Withincrease of quality and quantity of leaching water the wheat grain and straw yield stemand spike length number of grains per spike number of seedlings percent of emergence weight of 1000 grains and harvest index increase and lower Cl and Na concentrations ofwheat decrease As salinity of irrigation water increased the salinity of drainage waterincreased and the volumes of irrigation and drainage water decreased Application ofleaching in the best and worst irrigation water qualities salinity of 4 and 12 dS m hadthe most and worst leaching efficiency respectively The most saline drainage water andthe most changes in salinities of drainage waters were belonged to the three firstirrigations at the beginning of the season In later irrigations the changes in drainagewater decreased significantly and change process became nearly consonant
