“…These results followed a similar pattern of response to tiller population and emphasized the negative effect of severe shading on pasture in the SPS, especially in the summer. Decreases in the forage productions in shaded systems were observed by other authors (Bosi, Pezzopane, Sentelhas, Santos, & Nicodemo, ; Neel & Belesky, ; Santos et al., ). The strong restriction of PAR compromises the photosynthetic capacity of the plants, reducing the production of the components of the forage mass (Santiago‐Hernández et al., ).…”

Silvopastoral system (SPS) has been suggested to ensure sustainability in animal production systems in tropical ecosystems. The objective of this study was to evaluate the productive and nutritive value traits of Brachiaria decumbens and performance of dairy heifers in SPS and open pasture (OP) during the summer and autumn of two consecutive years in the SPS and OP (17th and 18th years after establishment). Experimental design was a randomized complete block with two treatments (SPS and OP) and three replications in subdivided plots with repeated measures in time. There was reduction in the tiller population density, total and green forage mass, and total and green forage bulk density in the SPS when compared to the OP in the summer. In the autumn, no difference was observed between the systems. Shading in SPS increased crude protein content of the grass pasture by 25% and 33% when compared to the OP during the first and second experimental years, respectively, and reduced neutral detergent fibre content. However, it did not change acid detergent fibre or lignin content. OP provided higher stocking rate and weight gain per area than the SPS. Average daily gain was higher in the OP in the second experimental year. Severe shading conditions should be avoided, because in the long‐term they may threaten the persistence and sustainability of pasture in the SPS. It is recommended to plant a low density of trees or implement management strategies of the tree component by either thinning or pruning over the years after planting.

“…Trees and shrubs can deliver forage alongside several other ecosystem services, including carbon storage, soil fertility, flood defence and biodiversity enhancement, and there has been recent research interest in quantifying the benefits of silvopastoral livestock systems (Santos et al 2016), particularly in restoring degraded pasture (Yamamoto et al 2007). Trees can provide supplementary forage, because tree foliage has different nutritional profiles to other functional groups and trees are also productive during the times of the year when other plants are scarce (Salem et al 2006).…”

Forage plants are valuable because they maintain wild and domesticated herbivores, and sustain the delivery of meat, milk and other commodities. Forage plants contain different quantities of fibre, lignin, minerals and protein, and vary in the proportion of their tissue that can be digested by herbivores. These nutritive components are important determinants of consumer growth rates, reproductive success and behaviour. A dataset was compiled to quantify variation in forage plant nutritive values within- and between-plant species, and to assess variation between plant functional groups and bioclimatic zones. 1255 geo-located records containing 3774 measurements of nutritive values for 136 forage plant species grown in 30 countries were obtained from published articles. Spatial variability in forage nutritive values indicated that climate modified plant nutritive values. Forage plants grown in arid and equatorial regions generally contained less digestible material than those grown in temperate and tundra regions; containing more fibre and lignin, and less protein. These patterns may reveal why herbivore body sizes, digestion and migration strategies are different in warmer and drier regions. This dataset also revealed the capacity for variation in the nutrition provided by forage plants, which may drive consumer species coexistence. The proportion of the plant tissue that was digestible ranged between species from 2 to 91%. The amount of fibre contained within plant material ranged by 23–90%, protein by 2–36%, lignin by 1–21% and minerals by 2–22%. On average, grasses and tree foliage contained the most fibre, whilst herbaceous legumes contained the most protein and tree foliage contained the most lignin. However, there were individual species within each functional group that were highly nutritious. This dataset may be used to identify forage plant species or mixtures of species from different functional groups with useful nutritional traits which can be cultivated to enhance livestock productivity and inform wild herbivore conservation strategies.Electronic supplementary materialThe online version of this article (10.1007/s10265-018-1024-y) contains supplementary material, which is available to authorized users.

“…This was achieved by increasing plant height, culm and leaf elongation (i.e., etiolation) (Goh et al., ; Martins et al., ; Valladares et al., ), hence increasing total plant biomass. As tree shading (Santos et al., ) and crop shading (Neves Neto, Santos, Alexandrino, & Santos, ) are known to reduce forage production in B. brizantha cv. BRS Piatã pastures, it could be inferred that co‐inoculation would be a suitable strategy to counteract limited pasture growth in integrated systems.…”

“…Integrated crop‐livestock‐forestry systems are efficient land‐management alternatives for restoring degraded pastures, increasing food security and promoting carbon sequestration (Dias‐Filho, ; Moraes, Carvalho, Lustosa, Lang, & Deiss, ; Paciullo et al., ; Santos et al., ). However, as the forage grass species planted in integrated systems may be subjected to light restriction, imposed by agricultural crops or tree species, it is necessary to know their agronomic performance under shade, to define their potential use in these systems (Dias‐Filho, ; Gomez, Guenni, & Bravo De Guenni, ; Paciullo et al., ; Pimentel et al., ).…”

This is the first report on the effect of light intensity and plant growth‐promoting rhizobacteria (PGPR) on the growth of a tropical forage grass, being a relevant study to improve pasture management in conventional farming and integrated crop‐livestock‐forestry systems. In this study, our aim was to evaluate the effects of light intensity and Burkholderia pyrrocinia and Pseudomonas fluorescens inoculation on Brachiaria brizantha cv. BRS Piatã growth, and phenotypic plasticity to shade. The experiment was conducted in a semi‐controlled environment. Seedlings of B. brizantha were allocated to full sun and shade. P. fluorescens and B. pyrrocinia were inoculated individually or co‐inoculated by soil drench, 14 days after seedling emergence. We evaluated morphogenesis, structural and growth parameters. Irrespective of the light regime, co‐inoculated plants had greater leaf area and SPAD index (chlorophyll content). Increase in total biomass production in co‐inoculated plants was over 100% and 300%, under full sun and shade respectively. Co‐inoculated P. fluorescens and B. pyrrocinia increased shade tolerance in B. brizantha, improving plant performance. Co‐inoculation promoted growth in B. brizantha under both sun and shade, indicating its potential as a bio‐fertilizer in conventional and integrated systems, especially in silvopastoral systems, where light availability to pasture growth may be limited.
