EFFECTS OF DIFFERENT SALINITY LEVELS WATER ON TRICKLE-IRRIGATED CORN YIELDS

摘要

The present study was carried out to evaluate the corn yield, yield loss, salt accumulation in the soil profile and water use efficiency in relation to the salt concentration levels of irrigation water applied with a trickle system on a clay-textured soil in the Mediterranean Region of Turkey. Saline irrigation water with electrical conductivities of 3.0, 6.0, 9.0, and 12.0 dS/m along with canal water of 0.5 dS/m was used. In addition, three treatments were included in the study by applying 10% leaching fraction to 0.5, 6.0, and 12.0 dS/m treatments after flowering. The amount of water applied to each treatment plot was based on cumulative evaporation from Class A pan within the irrigation interval of 7 days.
