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