Table 1_Water–fertilizer coupling balances yield and the input-related carbon footprint in double-cropping greenhouse Hami melon.docx Zhenliang Song (25152291) Ming Hong (240203) Quanjiu Wang (822044) Han Guo (228654) Fanfeng Dang (25152294) Guangning Wang (2541544) Zhaoxin Liu (3798190) Liang Ma (37793) Plant Biology carbon concentration carbon dilution effect carbon footprint Hami melon structural equation model water–fertilizer coupling <p>Water–fertilizer management is central to balancing productivity and environmental performance in greenhouse agriculture. Methods: In a spring–autumn greenhouse Hami melon system in Xinjiang, five irrigation (W1–W5) and three fertilization (F1–F3) levels were combined. Life cycle assessment quantified the input-related carbon footprint, plant carbon storage was measured, and structural equation modeling (SEM) evaluated associations among inputs, biomass, yield and carbon-footprint intensity. Results: Production inputs generated 12.77 t CO₂-eq ha^-1, with fertilizers (54.52%) and plastic film (23.16%) as the main sources. W4F3 achieved the highest yields (75.74 and 52.79 t ha^-1 in spring and autumn, respectively) and plant carbon storage (up to 35.78 g C plant^-1). In the fitted SEM, yield was strongly negatively associated with product carbon-footprint intensity (β = −1.253, P < 0.001), whereas area-based emissions were positively associated with it (β = 0.729). Under low irrigation, increasing fertilization did not consistently increase yield, while adequate water enabled fertilizer inputs to be converted more effectively into biomass and yield. Conclusion: Under the tested sandy-soil, cultivar and one-year greenhouse conditions, W4F3 (approximately 3420 m³ ha^-1 irrigation and 863 kg ha^-1 fertilizer) provided the most favorable balance between yield and product carbon-footprint intensity.</p> 2026-10-01T04:42:32Z Dataset Dataset 10.3389/fpls.2026.1917283.s001 https://figshare.com/articles/dataset/Table_1_Water_fertilizer_coupling_balances_yield_and_the_input-related_carbon_footprint_in_double-cropping_greenhouse_Hami_melon_docx/34038840 CC BY 4.0
