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.

The study was conducted on the water quality of Tigris River in upstream of AL-Kut Barrage during the period of August 2018 to June 2019. Six vertical sections have been selected upstream of Al-Kut Barrage. The distance between one section to another was 100 m, the first section begins at 350 m from the origin of Barrage. The result showed that the values of cadmium ion were 0.0346 ug/L to 0.0707 ug/L. The Lead values of the Tigris River water samples were 4.29 ug /L to 8.33 ug /L. The values of nickel ion have been ranged between 7.59 ug/L to 9.75 ug/L. Zinc ions have been recorded 53.5 ug /L to 72.1 ug /L. The concentration of above ions was situated within Iraqi and world Health organization (WHO) criterions that relating with propriety of water of Tigris River for drinking and irrigation.

An experiment has been conducted to study the effect of the quality of irrigation water quality and festination with Potassium and KSC in wheat (Triticum aestivum) cv Moelhu growth productivity. Eight treatments were applied ; irrigation with river water , drainage water , river water plus Potassium humate , river water plus KSC , river water plus Potassium humate plus KSC , drainage water plus Potassium humate , drainage water plus KSC , drainage water plus Potassium humate plus KSC . The treatments are put in completely randomized design with three replications . The parameters measured included ; plant height , spike length , total chlorophyll in SPAD , biological yield , grain yield , harwst index and NPK leaves content .
The results show outweigh the treatment of river, the added organic matter type Slphoric acid and type Potassium humate as compared with the other proportion like the rate of chlorophyll in the leaves, while not it's significantly different from the treatment by drainage water that added organic matter to both previous properties, but it's significantly different as compared with it by plant height feature . and the drainage water excelled with added two types of organic matter in the character of the length of the tufts compared with the comparison treatment and treatment of river water that the added matter of both two types of organic material that are used in the experiment.

The study was designed to determine the physical and chemical properties of some water sources and investigate their suitability in irrigation. The samples are taken from stored and stagnant water in a pool (20x10x2 m) to irrigate agricultural fields in the College of Agriculture, University of Qadisiya, it is compared with sewage and tap water also water reverse osmosis was used as a control. The water samples are categorized depending on the values of electrical conductivity and sodium adsorption ratio according to US Salinity Laboratory. The effect of four types of water also is studied in plant of tomatoes Lycopersicum esculntum conditions under the canopy by some external morphological characteristics and physiological as stressed indicators.
Electrical conductivity values are ranged between (0.066- 1.856 ds.m-1). The pH values are between (3.7 - 3.8) and the total suspended solid are ranged from (0.01- 87.85 mg / L, while the results have been recorded between (103.4- 1120) mg /l of total solids of the treated water and wastewater respectively. The results of chemical analyses show that total alkalinity and hardness of wastewater samples are very high (445.35 mg/l and 603.16 mg/l), while decreases to (27.6 mg/l and 41.65 mg/l) for RO treated water respectively. The concentrations of cations (Na, Ca2, Mg2, K) are between (- 37.9 - 77.3) and (8.5-37.57) and (15.3- 179.56) and (66.6-255.7) mg/l for each element in the treated water and wastewater respectively. While anions (, PO4, Cl, NO2, NO3, SO4 record high ranges for wastewater between (47.9- 477.81) and (6.8-465.28) and (0.16- 59.41) and (7.59-234.96) mg/l respectively. The study also shows that the soluble sodium percentage records the highest value in the treated water (54.5%) and the lowest value is detected in the pond water (38.32%). The sodium adsorption ratio is ranged between (2/1- 4/30) for RO water and wastewater respectively, While the exchangeable sodium percentage is ranged between (0.45-87.16) for both types of water respectively.
The results shows the total chlorophyll values were reduced in plant of tomatoes irrigated with wastewater to (3.2 mg/g fresh weight) while the highest value is recorded 5.2 in irrigated plants with RO water. However, chlorophyll a values are ranged between (0.94-1.37) mg/g in irrigated plants with wastewater and RO water treatment respectively, while chlorophyll b values are ranged from (0.39-0.52) and the ratio of Chl. a / Chl. b. was 2.33-2.64 in the pond water and treated water respectively. The total content of carotenoid is decreased to (0.08) mg/g of fresh weight in the wastewater treatment to 0.56 mg/g in RO water treatment, the chlorophyll stability index was between (90.4-62.7%) in irrigated plants with tap water and sewage water respectively. The percentage of permeability to electrolytes increase to (49.8%) in irrigated plants with pond water.
