“…Santos et al. (2020) observed reductions of 40 and 60% in CBD of a SPS with increased shade to relative full sunlight. Greater CBD observed in signalgrass growing in the SPS–mimosa is likely a function of shorter canopy height because CBD typically is greater in the lower canopy stratum (Sollenberger & Burns, 2001).…”

Tree legume enhances livestock performance in a silvopasture system

Silvopastoral systems (SPSs) can increase overall productivity and long‐term income due to the simultaneous production of trees, forage, and livestock. This 2‐yr study evaluated animal performance and herbage responses in C4–grass monoculture or in SPS in the subhumid tropical region of Brazil. The experimental design was a randomized complete block with three replications. Treatments were: Urochloa decumbens (Stapf.) R. Webster (Signalgrass) + Mimosa caesalpiniifolia Benth (SPS–mimosa), Signalgrass + Gliricidia sepium (Jacq.) Kunth ex Walp (SPS–gliricidia), and signalgrass monoculture (SM). Response variables included herbage and livestock responses. Cattle were managed under continuous stocking with variable stocking rate. There was a treatment × month interaction for herbage mass. Green herbage accumulation rate ranged from 20 to 80 kg dry matter ha−1 d−1 across months, with SPS–mimosa presenting lower rates. Average daily gain was greater in SPS–gliricidia, followed by SM and SPS–mimosa (0.77, 0.56, and 0.23 kg d−1, respectively), varying across months. Stocking rate ranged from 0.86 to 1.6 AU ha−1. Total gain per area during the experimental period was greater for SPS–gliricidia (423 kg body weight [BW] ha−1), followed by signalgrass in monoculture (347 kg BW ha−1) and SPS–mimosa (50 kg BW ha−1). Silvopasture systems using signalgrass and gliricidia enhanced livestock gains compared with signalgrass in monoculture, and mimosa trees outcompeted signalgrass, reducing livestock gains. Silvopasture systems with tree legumes have the potential to provide numerous ecosystem services and to reduce the C footprint of livestock systems in the tropics; however, the choice of tree species is key and is determined by which ecosystem service is prioritized.

“…The wide adaptation potential of these legumes, ranging from semiarid to humid areas, increases the scope for their utilization (Dubeux, Muir, et al, 2017). Most studies in Brazil with tree legumes have been conducted in an ecoregion considered a transition zone between the Atlantic rainforest and the semiarid Agreste region (average annual rainfall is approximately 1,200 mm, with an average annual temperature around of 25°C; Apolinário et al., 2015; Apolinário et al., 2016; Lima et al., 2020; Dos Santos, Dubeux et al, 2020).…”

“…In relation to forage and animal performance, the reduction of light intensity for the herbaceous component in silvopastoral systems can affect morphological and physiological aspects that are determinants for the productivity and quality of forage (Lima et al., 2020). Therefore, tree legumes may reduce grass herbage accumulation, which may result in reduced animal performance per unit area (Lima et al., 2020; Dos Santos, Dubeux et al, 2020). However, the multifunctionality of tree legumes allows the provision of other incomes, such as timber, lumber and firewood (Dos Santos, Dubeux et al, 2020).…”

Tropical forage legumes were first used on a wide scale, starting well before the 1950s in the northeasterly Australian state of Queensland (Shaw, 1961). The famous "Townsville Stylo" (Stylosanthes humilis Kunth) was introduced into thousands of ha of pastures in Queensland and made an important contribution to extensive beef production in northern Australia (Gardener, McCaskill, & McIvor, 1993; Humphreys, 1967). Many Brazilian students working on pastures and agronomy studied in Australia in the 1960s and 1970s and brought back the idea of using Stylosanthes spp. in Brazilian pastures. The Centro Internacional de Agricultura Tropical (CIAT), Cali, Colombia, starting in the 1970s, accumulated a large collection of forage legumes, listed today as 21,083 tropical legume accessions, including over 4,000 of the genus Stylosanthes alone (CIAT, 2019). A considerable effort was made to work with this germplasm in Brazil, mainly by Embrapa and CEPLAC. The first Stylosanthes materials tested were highly sensitive to the fungal disease anthracnose and resistant accessions had to be selected. In Brazil, two cultivars of Stylosanthes were released in 1983, Pioneiro and Bandeirantes, and while in trials their performance was satisfactory (Sousa, Andrade, & Thomas, 1983a, 1983b) there was
