The study aimed to establish the nexus among biological efficiency and forage production by analyzing the canopy structure and light interception potential in orchard grass (Dactylis glomerata), alfalfa (Medicago sativa), and white clover (Trifolium repens). The measurements were performed in Gherghita Plain, at Pucheni village on large plots in 2023 by using the Delta-T Devices Sunscan Analysis system. The leaf area index (LAI), light parameters, and microclimate indicators were retrieved in each canopy of the studied species at various layers of 10 cm from the bottom to the top of the canopy. Consequently, a close relationship was observed between the biological efficiency, the leaf area distribution, and potential forage production for both grass species and legumes. The results are useful for planning biometrical parameters when developing new performant cultivars.
