Winter wheat is a vital grain crop in Xinjiang and severe water scarcity this arid region necessitates efficient irrigation strategies for sustainable production. A two-year field experiment (2022-2023) northern was conducted to evaluate the effects of sowing patterns drip levels on winter growth yield. Two were tested: uniform row spacing (CK1, 15 cm) wide-narrow spacing, comprising 13.3 cm + 20 (M1), 10 30 (M2), (M3). Four applied: 4500 mm2/hm2 CK), 3600 m³/hm² (D1), 2700 (D2), 0 m2/hm2 (D3). The results indicate that increased single-plant dry matter weight, with stem sheath spike allocation ratios at maturity increasing by 15.31% 6.59%, respectively. Wide-narrow rows improved traits, particularly outer rows, length number per 0.46% 0.68%, respectively, reducing sterile spikelets 1.35%. Compared CK1D1 treatment, M2D1 treatment significantly spikes unit area, grains spike, yield 19.15%, 5.92%, 19.10%, no significant difference thousand-kernel weight. These findings demonstrated optimized water-saving efficiency, providing critical guidance production regions.
