Code and derived tables for: Closing the Irrigation Guidance Gap: Simplified Evapotranspiration-Based Drip Scheduling for Cotton in Jizzakh, Uzbekistan

Analysis code and derived tables supporting the article Closing the Irrigation Guidance Gap: Simplified Evapotranspiration-Based Drip Scheduling for Cotton in Jizzakh, Uzbekistan. The archive contains: (1) the reproduction of the field results (Phase I paired drip–furrow trials, 2021–2023; Phase II difference-in-differences farmer panel, 2022–2023) from the public field dataset, version 2.0, a copy of which is included; (2) the Phase I design-schedule analyses (design volume by phenological stage; the 2023 event-level schedule and its crop-coefficient curve); (3) the interannual stability screen of the seasonal net irrigation requirement and of FAO-56 reference evapotranspiration across 14,445 second-level administrative units of Asia and Africa (0–60°N), 1991–2023, from Copernicus AgERA5 v2.0, under three effective-rainfall conventions; (4) the table-transfer and anomaly-coherence radii; (5) the MapSPAM 2020 cotton-area mask; (6) the weighted set-cover hub network for Uzbekistan's cotton area, solved on reference evapotranspiration and on the net irrigation requirement; (7) the design schedule against the requirement of each season at the experimental grid cell; and (8) the scripts that draw the main-text figures. Raw reanalysis, MapSPAM and GADM inputs are not redistributed; README.md gives download instructions, product versions and a map from every article table and figure to its script and output. Additional analyses not reported in the article, including a single-July ERA5-Land diagnostic, are listed separately in README.md.
