This research determined the effects of conservation tillage practices on the soil quality parameters and productivity of winter wheat (WW) followed by soybean (SB) under a conventionally irrigated arid environment. The field experiments were conducted over 2020-2023 in a split-plot design with the following four land management practices: conventional tillage (CT: mouldboard plow + disk + harrow), RT1 (chisel + harrow + disk), RT2 (chiseldisk + harrow), and NT (no-till -without tillage). After three experiment cycles, the soil humus content increased by 10, 12, and 15% (P < 0.05) in the CT, RT1 and RT2 plots, respectively, while the highest soil humus was detected in the NT plot. The soil bulk density decreased from 1.6 g/cm 3 to 1.33, 1.42, and 1.34 g/cm 3 (P < 0.05) in the CT, RT1 and RT2 plots, respectively. A significant increase was found at the NT plot in terms of soil quality indicators such as total N and P, available N-NO3, P2O5 and K2O. The application of NT increased the yield components by 20% and 12% of WW and SB, respectively, compared to CT. This study showed that the highest WW (6.84 Mg ha -1 ) and SB (2.12 Mg ha -1 ) grain yields were produced under the NT plot, most likely because more moisture and nutrient conservation were explored due to the high amount of crop residues on the soil surface. The implemented NT method combined with the legumebased cropping system appears to be a more sustainable and environmentally friendly land management system for achieving a favorable soil environment, which generated higher crop yield in this the arid ecosystem.
