Effect of Chemical Correction of Irrigation Water on a Barley Crop

The lack of fresh water for irrigation in the world, especially arid and semi-arid areas is often posed as a major problem agriculture, which requires research to valorize saline water. This work aims study impact chemical correction quality on barley. corrected waters were prepared from raw by applying doses calcium represented Ca(NO3)2 4H2O according their soluble sodium content, whose aim balance two contents. treatments are five types different salinity S1, S2, S3, S4 S5 well S1C, S2C, S3C, S4C S5C. parameters studied are: length stems, spike, number grains per grain yield, straw yield weight 1000 grains. results obtained show that has positive effect yield. Calcium reduces harmful alleviates aggressiveness salinity.
