Special Issue Information

Dear Colleagues,

The urgent need to ensure global food security while preserving environmental integrity has placed sustainable agriculture at the center of scientific and policy discussions. This Special Issue aims to explore innovative strategies, technologies, and policies that contribute to the development of sustainable agricultural systems that are capable of addressing current and future challenges. Topics of interest include, but are not limited to, the following: climate-smart agriculture, soil and water conservation, agroecology, bio-based inputs, precision farming, renewable energy integration, and circular economy practices in agrifood systems. We particularly seek papers focused on interdisciplinary approaches and scalable solutions that promote environmental resilience, economic viability, and social inclusion. Contributions may include original research, case studies, reviews, and policy analyses addressing sustainability in both crop and livestock systems across diverse agroecosystems. This Special Issue additionally welcomes insights into emerging tools such as artificial intelligence, biotechnology, and digital agriculture that hold promise in providing a more sustainable and productive agricultural future. By gathering scientific knowledge and applied innovations, this collection of papers hopes to enable the transition towards productive and regenerative agriculture, aligning with the principles of sustainability.

White clover (Trifolium repens L.) is a major legume in Mediterranean agroecosystems. This study systematically evaluates 15 autochthonous white clover populations from the Trikala region of Greece, focusing on chemical composition and derived nutritional indices relevant for germplasm characterization and breeding. Fifteen local populations were evaluated under controlled pot cultivation over two consecutive years. Clonal plants were harvested at the early flowering stage. Key traits—crude protein (CP), Ash, Fat, crude fibre (FIBRE), acid detergent fibre (ADF), neutral detergent fibre (NDF), digestible dry matter (DDM), dry matter intake (DMI), and relative feed value (RFV)—were measured. Combined ANOVA revealed significant differences among populations for all traits (p ≤ 0.001), while genotype × year interactions were present but generally minor compared to genotypic effects. Broad-sense heritability was high across most traits (H2 = 90.8–99.4%), demonstrating strong genetic control. CP showed positive correlations with DDM, DMI, and RFV, whereas ADF and NDF were negatively correlated with intake and digestibility. Canonical and discriminant analyses showed that a reduced set of traits (CP, Ash, FIBRE, RFV) contributed strongly to differentiation among populations. Hierarchical clustering (heatmap) confirmed these groupings based on fibre and digestibility-related traits. Populations such as Dendrochori and Gorgogyri consistently showed favorable chemical and nutritional profiles, while Fiki and Dendrochori showed the highest stability across years. The present study highlights substantial genetic variability among local white clover populations and identifies trait structures of relevance for germplasm characterization. These findings enhance the characterization of genetic diversity in Trifolium repens and support its potential use in future breeding research under Mediterranean environments. Full article

Castor (Ricinus communis) is a toxic seed used to extract oil for the chemical industry, with castor meal as a by-product. A recently developed industrial method allows its detoxification, enabling its use as a protein-rich feed for ruminants. This study evaluated the safety of detoxified castor meal based on intake, digestibility, and performance of sheep fed sugarcane silage containing increasing levels of this ingredient. The detoxified castor meal, supplied by an oil extraction industry, underwent no additional detoxification treatment. Twenty-four intact male sheep were randomly assigned to diets containing 0%, 10%, 20% or 40% fresh matter castor meal in sugarcane silage. Diets were balanced with soybean meal and ground corn. After 60 days of feeding, no signs of intoxication were observed. Crude protein (CP) intake decreased from 0.157 to 0.128 kg/day (p = 0.03) and ether extract (EE) intake from 0.068 to 0.044 kg/day (p = 0.04). Crude protein digestibility declined from 754 to 473 g/kg (p < 0.01), and EE digestibility from 813 to 725 g/kg (p = 0.02). All other intake, digestibility, and performance variables were not significantly affected (p ≥ 0.05). Industrially detoxified castor meal was shown to be a safe additive in sugarcane silage up to 40% by fresh matter, with no adverse effects on sheep performance. Full article
