Abstract:
This study evaluates the agronomic and physiological response of coriander (Coriandrum sativum L.) to periodic shading induced by a Mobile Agrivoltaic Installation (MIA) under field conditions in north-central Poland. The experiment was conducted in Minikowo during the 2024–2025 growing seasons using a bifacial photovoltaic system mounted on a mobile 4×4 platform. In 2025, the MIA functionality was extended with the integration of an automated drip irrigation system. The effects of transient shading on plant density, canopy height, seed yield, Thousand Seed Weight (TSW), photosynthetic performance (Leaf Area Index (LAI), Chlorophyll Content Index (CCI), and PSII), and chlorophyll fluorescence were assessed. Results showed that MIA shading reduced plant height and seed yield slightly (−4.7%), but significantly increased seed size (TSW +28%) and number of lateral branches (+40%) compared to the control. Despite lower plant density and number of seeds per plant, the shaded coriander showed signs of morphological adaptation and photosynthetic resilience, including high PSII efficiency (0.826) and increased CCI index values. The mobile shading system also contributed to more stable soil moisture and light diffusion without negatively affecting post-harvest regrowth. These findings suggest that coriander tolerates intermittent shading well and can be cultivated under mobile agrivoltaic systems without major productivity losses. This study supports the feasibility of integrating MIA in medicinal plant cultivation as a dual land-use strategy for energy and crop production in temperate zones.
