Herbage accumulation dynamics in mixed pastures composed of kikuyugrass and tall fescue as affected by grazing management

Abstract

In many subtropical regions, the annual thermal amplitude and the absence of a well-defined dry season allow the cultivation of forage grass species in both the cool and warm seasons, allowing pasturebased animal production year-round. Generally, this is achieved by sod-seeding annual cool-season species such as annual ryegrass (Lolium multiflorum) or oats (Avena strigosa) into annual/perennial C4 species. A similar (but much less explored) alternative to animal production models in subtropics is the mixture of perennial cool-and warm-season forage grasses. One of the warm-season perennial grasses well adapted to regions with a temperate oceanic climate (Cfb), where mean air temperature in the hottest month is below 22℃ (Alvares et al., 2013), is kikuyugrass (Pennisetum clandestinum; Bell et al., 2013;García et al., 2014). When growing in such environments, most forage of this species is produced during the summer/

“…Forage production is the base of animal husbandry, and prataculture development is the guarantee to meet people's requirement for meat and milk (Bernardon et al, 2021). Regrowth following defoliation is a forage grass growth strategy to overcome herbivory and environmental stress‐induced damage (Wang et al, 2012).…”
