A field experiment was carried out in the Badia of Al-Muthanna, Faidat Umm Al-Shih, for the 2018-2019 season, to determine the effect of adding levels of agricultural polymer and levels of irrigation on some chemical and physical properties of the soil and the production of wheat crop (Triticum aestivum L.). The experiment included three levels of Absorption Sup super (ASP Polymers (0, 40 and 80) kg ha (P0, P1 and P2) and four levels of irrigation (W3, W4, W5 and W6). Three seasons, four seasons, five seasons, and six seasons, the soil was divided into three replicates to find out the best number of irrigations with the best amount of polymer added in production and the characteristics of the studied soil. The results showed the effect on the soil properties, the addition of the agricultural polymer at a level of 80kg ha and the irrigation level W6 showed a significant decrease in the electrical conductivity of the soil, reaching 1.9 decimens, the CEC values ​​also increased to 13.80 cmol, which is the highest level, and the bulk density values ​​decreased to the level of 1.39 gm cm3, which was the lowest level in the experimental treatments. As for the soil reaction, it reached the lowest level (7.60 pH) against the level of polymer P1, as for the effect on wheat production, it was significant, as the biological yield reached the polymer level 80 kg ha, 11.95 megagrams ha-3, which was the highest production achieved by the experimental treatments, while the yield of the wheat crop was 5.55 megagrams ha-3, which was the highest. The effect of irrigation levels on biological production and productivity reached the highest irrigation level (W6), where it was respectively 11.40 and 4.51 mg ha-3 as an average, as the study showed that the addition of 80 kg/ha agricultural polymer with six irrigations per season gave good productivity and significantly affected Positive on soil physical and chemical properties in desert soils
