This dataset contains the model inputs, scenario configuration and NECADA XML outputs supporting the analysis of plastic mulching within the Water–Energy–Food–Ecosystem (WEFE) Nexus at the Moroccan Digital Citrus demonstrator (DS3), INRA Menzeh, Morocco. The dataset includes the four citrus varieties Gharbaouia, Mahdia, Shamssia and Valencia, four mulching-factor scenarios (MF = 1.0, 0.9, 0.8 and 0.7), and three tank-filling electricity-supply configurations (0%, 30% and 100% photovoltaic). XML outputs underpin the irrigation, electricity-demand, GHG and integrated WEFE calculations reported in the associated manuscript.
