Summary
Hemp cultivation revitalizes marginal lands, with cultivars varying in suitability for seed, bioactive compounds, or multi-purpose use. Secuieni Jubileu (JUB) excels in seed production, Carmagnola Selezionata (CS) in bioactive compounds, and Futura 75 (FUT) for versatile applications.
Area of Science:
- Agronomy
- Botany
- Sustainable Agriculture
Background:
- Marginal lands face abandonment; agricultural diversification with sustainable crops like hemp offers revitalization.
- Hemp (Cannabis sativa L.) presents potential for high-value products and economic resource generation.
Purpose of the Study:
- Compare four hemp cultivars (Carmagnola Selezionata, Futura 75, Felina 32, Secuieni Jubileu) for cultivation in mountain marginal areas.
- Evaluate ecological, agronomic, and nutraceutical profiles for cultivar selection and specific end-use applications.
Main Methods:
- Field cultivation of four hemp cultivars to assess life cycle, plant size, biomass allocation, and resource-use strategies.
- Metabolomic analysis of vegetative and reproductive parts to identify nutraceutical compounds and seed nutritional profiles.
Main Results:
- Significant variations observed in ecological, agronomic behavior, and nutritional profiles among the four cultivars.
- Secuieni Jubileu (JUB) is most suitable for seed production; Carmagnola Selezionata (CS) shows highest bioactive compounds in flowers/leaves.
- Futura 75 (FUT) is best for multi-purpose cultivation, while Felina 32 (FEL) is less suitable for mountain environments.
Conclusions:
- Hemp demonstrates high potential for cultivation in marginal lands, offering economic benefits through multi-purpose use and high-added value products.
- The study provides crucial data for farmers to select optimal hemp cultivars, stimulating reintroduction in similar environments.
