Special Issue Information

Dear Colleagues,

Grasslands represent a benefit for agro-ecosystems that Europe is committed to the preservation, protection, and promotion due to their economic, social, cultural, landscape, and environmental roles. These goals can be achieved only through the active and sustainable management of such resources, based on an accurate and careful analysis of grassland-based farming systems, especially the complex and diverse vegetation that characterises grassland environments. Therefore, the interaction among grassland species and human activities warrants in depth study, especially in the context of the current extreme situations of agriculture abandonment and intensification, both affecting grassland environments.

This Special Issue focuses on the role that management could play in preserving and enhancing grassland species richness and in the importance of such species within agricultural production systems. For this reason, we welcome high-quality interdisciplinary studies from various research fields, including agriculture, agro-environmental policies, applied botany, environmental sciences, genetics, grassland restoration and improvement, innovation technologies, landscaping, and soil–plant interactions. Original research articles and reviews are accepted.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agriculture is an international peer-reviewed open access monthly journal published by MDPI.

Tangolagrass (Brachiaria arrecta × Brachiaria mutica) is a stoloniferous warm-season grass considered as an alternative to forming permanent grasslands in waterlogged tropical regions. However, information about grazing management targets for such species is still scarce. This two-year study aimed to identify pre-grazing canopy heights that do not compromise both leaf lamina production and nutritive value of tangolagrass pastures, and to test whether lower canopy height could decrease stolon elongation process. To this end, three pre-grazing canopy heights (20, 30, or 40 cm, all lowered in 40% of their initial heights) were assigned to nine 390-m2 plots grazed by cattle. Herbage, leaf, and stem accumulation rates were not different among treatments (57, 23, and 27 kg DM ha−1 d−1, respectively; p > 0.05). Also, neutral detergent fiber (NDF) and acid detergent fiber (ADF) were similar among treatments (56 and 24% DM, respectively; p > 0.05), but crude protein (CP) was greater (p = 0.0180) in pastures managed with 30 cm (24.7% DM × 22.5% DM). Thus, pre-grazing canopy heights between 20–40 cm combined with low levels of defoliation (up to 40% of the initial height) provide the same primary productivity in tangolagrass pastures. However, stolon elongation could not be reduced within such canopy height targets. Full article
