| Abstract |
The circular economy is based on sustainable production and consumption. In terms of circular economy, sustainable agriculture is achieved through the effective use of internal resources to self-produce and use, without waste production, green preparations for the fertilization and protection of crops. In this context, the project of a certified organic farm aims to cultivate medicinal plants to self-produce aqueous extracts of thyme and tansy, for use in crop protection, and reuse residues for composting and mulching. Regarding the environmental and economic impact, a virtuous process of cultivation and defense of agricultural crops was carried out (three-year rotation of zucchini-cabbage-chicory), to respond to market demand and to implement safety and health protection policies for farm workers and consumers. In a preliminary germination test, a stimulating effect was observed on Vicia faba seeds treated with thyme extract in which the greater elongation of the primary roots, relative to the control, was statistically significant. The effects of the extracts on the crops (weight and chlorophyll content) have always been significant. In particular, the chlorophyll content of chicory is highly significant for the remaining parameters measured for all horticultural crops in the field trial. |
