“…In view of this, upcoming no‐till reintroductions of stylosanthes in Brachiaria pastures can be an alternative to maintain the positive effect of legume on animal performance in the long term. For this, it is also necessary to determine the magnitude of the residual effect of stylosanthes on pasture after its disappearance (Menezes et al, 2015). Although the legume plant population has decreased to almost zero, it is reasonable to assume that legumes have a residual effect due to remaining plant parts and their effects on soil nutrient recycling.…”

The use of stylosanthes in mixed grass‐legume pastures may minimize the decline in forage quality and quantity that occurs in monoculture grass pastures, even though the availability of commercial cultivars in Brazil is still limited. The objective of the study was to evaluate the liveweight (LW) gain of young Nellore bulls in a mixed pasture of Brachiaria brizantha (cv. Paiaguás) with the latest release Stylosanthes guianensis cv. Bela. The study was conducted in Planaltina, FD, Brazil, from September to August in two consecutive years, right after seeding. The experimental design was a randomized complete block design with two treatments (mixed or monoculture Paiaguás pastures) and three replicates. The average daily gain (ADG) was on average greater in mixed pastures (0.436 vs. 0.350 kg head−1 day−1 in mixed and grass pastures respectively), particularly in the dry period (0.344 vs. 0.183 kg head−1 day−1). The benefit of mixed over monoculture grass pastures throughout the year was 22 kg LW/head and 55 kg LW/ha. The presence of stylosanthes increased the crude protein (CP) concentration in mixed pastures (120 g/kg) when compared to monoculture grass pastures (109 g/kg), probably influencing the ADG of bulls. The increase of liveweight gain, predominantly in the dry season, makes the high‐protein stylosanthes cv. Bela an alternative to buffer the seasonal deficit of forage quality in newly seeded grass pastures.

“…Nevertheless, the presence of Stylosanthes improves pasture in the first year of implementation, when the highest values of botanical composition are observed (Paciullo et al., ). In addition, more than 34% of legume presence leave a positive residual effect in the production of forage up to 1 year after their disappearance (Menezes et al., ).…”

Forage legumes from the genus Stylosanthes are frequently used as pasture cover crops with positive effects in controlling weeds, soil fertility and crop yield while providing livestock feed and additional income for farmers through seed production. Stylosanthes guianensis is native to South America and extensively grown worldwide. Therefore, efforts to improve this species may help the sustainability of livestock production in pasture areas managed with this legume. We evaluated 12 sister lines spread through seeds under clippings in the western Amazon region, Brazil. The results were analysed using the methodology of mixed models. Five sister lines mixed with the grass Brachiaria brizantha were evaluated under continuous grazing for two consecutive years. We estimated the genetic and phenotypic parameters of the forage legume and then identified and validated, under grazing, the sister lines most promising to be used in an area of the western Brazilian Amazon. Total dry‐matter yield, soil coverage, height before clipping, height after clipping and seed production showed low‐to‐moderate broad‐sense heritability (0.1–0.5), contrasting with reduced genetic variability for the characters associated with nutritive value. The S. guianensis lines had, on average, 278 g/kg of crude protein in the dry matter of the leaves and 200 g/kg in the stems, suggesting that the use of this species may help to overcome the low protein content of tropical pastures. There are promising stylo lines that can be used in mixed pastures in humid tropical regions.

“…According to Menezes et al (2015) would be necessary from 130 to 150 kg/ha of N to maintain the pasture productivity in areas with Xaraes palisadegrass two years after the disappearance of Brazilian stylo that exists in that pasture before, at the ratio of 34 and 52%. Also in this research Alves et al (2016) evaluated the production and morphogenic characteristics of Xaraes grass and concluded that there was a residual effect from the incorporated nitrogen to the system by the legumes.…”

. In this context, the introduction of forage legumes in the pasture system is fundamental to fix nitrogen from the atmosphere and supply it to grasses, increasing its production and persistence, enhancing animal nutrition as it grazes, at the same time. Still, the use of plant mixes in the system brings further benefits to it, such as better utilization of fertilizers as well as enhances the nutrient cycle and soil coverage. However, there are still many gaps in our knowledge regarding intercropping legumes and grasses, especially the use of tropical legumes. The purpose of this review is compiles data about forage legumes as well as analyses them to find new tendencies and gaps on the knowledge to shed some lights on researches in this area. We also expect that this review will help researchers and producers to understand the role of forage legumes in a pasture system and that there will be an increase in its utilization worldwide, especially in the tropics, where nitrogen is easily leached and lost from the pastures. With emphasis on description of promising tropical legumes but still little used Arachis pintoi, Macrotyloma and Neonotonia whightii.
