The Functionality Of Legume-Grass Swards In A Long-Term Pasture: Productivity And Stability, Žydrė Kadžiulienė, Lina Šarūnaitė, Leonas Kadžiulis

IGC Proceedings (1977-2023)

Combinations of various plant species or functional groups can enhance sward structure, the function and stability of an ecosystem, supplement forage production and mitigate negative environmental impacts. Climatic variation, rising temperatures, changing precipitation and other extreme climatic events may lead to changes in plant diversity (Soussana and Lüscher 2007). At the same time it is very important to optimise functional diversity by combining species with different properties that are well adapted to the local environments (Huyghe et al. 2012). Successful selection and management of legumes influences the herbage production, nutritional quality and sustainability of grazing systems. Therefore, their role …

Mixed Species Seeding: A Means To Increase Production In Temperate Pastures, Michael P. Schellenberg, Bili Biligetu, Valentin Picasso

IGC Proceedings (1977-2023)

Seeding mixed species for forage production has been suggested as a means of increasing productivity and stabilizing yields under a changing climate. Forages have traditionally been sown as monocultures or binary mixtures only, with the emphasis being on species and not necessarily their function or compatibility. While natural plant communities typically may be dominated by a single species, they are comprised of several species and function-al groups.

This paper provides the results of sowing multiple species at semiarid sites within the North American Great Plains and identifies a similar result from a more humid region reported within the literature.

Management Options That Increase Herbage Production In Grassland-Based Livestock Production Systems, Masahiko Hirata, Manabu Tobisa, Sachiko Idota

IGC Proceedings (1977-2023)

Herbage production is the most important measure of performance of grassland systems. Understanding how herbage production responds to various managements is crucial to the success of grassland systems, whether or not maximization of production is pursued. Most of the records of grassland production in the literature are taken as acceptable approximations of net herbage production. Analysis of these production records and accompanying quality data can generalize the response of grassland productivity and quality to individual managements, and can characterize the managements in terms of their efficiency and potential in increasing productivity and quality. Overall, maximum production response is ranked irrigation …

Response Of Selected Cultivars Of Sheep Fescue To Management Strategy In Extensive Lawn Utilization, Barbara Golińska, Piotr Goliński

IGC Proceedings (1977-2023)

Sheep fescue (Festuca ovina L. sensu lato) is distinguished for its ability to form sods on difficult sites (Dernoeden et al. 1994). This species is a persistent bunch grass that mixes well with wildflowers, without dominating them. For this reason sheep fescue can play an important role in the creation of landscape lawns. In the adaptation of this grass to extremely difficult sites, specific biological features of this grass are very important, especially water efficiency, drought tolerance, and low fertilizer requirements (Aronson et al. 1987; Brar and Palazzo, 1995).

The aim of this work was to …
