Compared with pure chemical fertilizer topdressing (CF), BSTR further increased post-tasseling dry matter (DM) accumulation, grain-filling characteristic parameters and yield components, with the increase amplitude gradually rising as the BSTR proportion increased. BSTR had greater potential to stimulate grain yield potential, with the pure biogas slurry topdressing treatment (100%BS) being the most representative, significantly increasing yield by 26.50 % and 14.76 % compared with the CF treatment in 2022 and 2023, respectively.

Furthermore, grain filling and dehydration directly affected yield components, while yield and NP were primarily subject to direct feedback regulation by treatment, years, and DM accumulation and redistribution.

The presence of these PC in VOO can be induced by many factors, such as agricultural management approaches. To evaluate the relevance of the agronomic practices as inducers of oleocanthal and oleacein in VOO, monovarietal VOO from three cultivars were produced —‘Cobrançosa’ (COB), ‘Arbequina’ (ARB), and ‘Galega vulgar’ (GV)—by a laboratory-scale extraction method, considering two distinct agronomic systems: organic and integrated farming systems.
