Abstract: The plant heritage of the Mediterranean basin, with its wide biodiversity, offers the best conditions to pursue the objectives of the EU Green Deal, and among it, we pointed our attention to the Brassica oleracea crops, thanks to the high number of landraces and of its wild relative species widespread both in agro and ecosystems. In the framework of the European project BRESOV H2020 “Breeding for Resilient, Efficient and Sustainable Organic Vegetable Production”, we evaluated different organic growing conditions and plant characteristics to pursue a good yield and high quality of organic seed under different nutrition protocols. We took in attention the two landraces of sprouting broccoli ( Brassica oleracea var. italica Plenk) Sparaceddu and Cavolo Riccio di Messina, which well express the traditional trait of broccoli Sicilian biodiversity that is often unfortunately underestimated. The results showed that the new tools for organic plant nutrition implement the plant characteristics and the related seed yield also by using a lower level of inputs, achieving economically sustainable production by the use of the nutrition protocols evaluated. There is, therefore, a strong need to affirm the concept of “minimum dose” in order to obtain a satisfactory result in terms of production and quality. The research also focused on the characteristics of brassicas crops, highlighting the main factors that render the use of biodiversity possible and profitable.
