Effect of different treatments to reduce the salinity of irrigation water on the growth and yield of wheat

Abstract

A field experiment was conducted under the conditions of Muthanna Governorate during the 2022-2023 agricultural season in one of the fields belonging to a farmer in the Al-Bandar area (3 km from the center of Samawah city), which is located at longitude 45.18 east and latitude 31.19 north. The experiment aimed to study the effect of different treatments in reducing the impact of irrigation water salinity on the growth and yield of wheat (Triticum aestivum L.). Variety Abaa 99 The experiment was conducted using a split-plot design with complete randomized blocks with three replications. The main plots included levels of irrigation water salinity with concentrations of (6, 9 and 12) dS m -1 in addition to the control treatment of normal river water (3) dSm-1 . The secondary plots included some salinity reduction treatments, namely (Kamasol, Clean Salt, magnetic irrigation water). The results of the experiment showed that the Clean Salt treatment significantly outperformed the control treatment in terms of plant height (95.50 cm), flag leaf area (34.07 cm2 ), number of tillers (412.50 tillers m2 ), and grain yield (6.210 t ha-1 ). While salinity levels significantly affected some of the studied traits, the irrigation water treatment (control) was superior in the flag leaf area, recording 35.61 cm2 . The 6 dS m treatment, on the other hand, outperformed the other treatments in terms of biological yield, recording the highest yield of 13.458 t ha-1 . The interaction between the factors of the experiment had a significant effect on some of the studied traits.
