“…Agroforestry systems with trees or shrub alleys within annual crop fields can be an option to reduce the fragility of certain agricultural production systems (Wick & Tiessen, 2008;Foroughbakhch et al, 2009;Li et al, 2009;Kurppa et al, 2010;Sousa et al, 2010;Lima et al, 2011). Those systems produce a considerable amount of biomass that can be incorporated into the soil, transferring nutrients from the trees to the crops (Bertalot et al, 2010;Munroe & Isaac, 2014).…”

-The objective of this work was to estimate the amounts of N fixed by cowpea in a traditional system and by cowpea and gliricidia in an agroforestry system in the Brazilian Northeast semiarid. The experiment was carried out in a randomized complete block design, in a split-plot arrangement, with four replicates, in the semiarid region of the state of Paraíba, Brazil. Plots consisted of agroforestry and traditional systems (no trees), and split-plots of the three crops planted between the tree rows in the agroforestry system. To estimate N fixation, plant samples were collected in the fourth growth cycle of the perennial species and in the fourth planting cycle of the annual species. In the agroforestry system with buffel grass and prickly-pear cactus, gliricidia plants symbiotically fix high proportions of N (>50%) and contribute with higher N amounts (40 kg ha -1 in leaves) than in the traditional system (11 kg ha -1 in grain and 18 kg ha -1 in straw). In the agroforestry system with maize and cowpea, gliricidia plants do not fix nitrogen, and N input is limited to the fixation by cowpea (2.7 kg ha -1 ), which is lower than in the traditional system due to its lower biomass production.Index terms: Gliricidia sepium, Vigna unguiculata, biological nitrogen fixation, natural abundance, 15 N. Nitrogênio fixado simbioticamente por feijão-caupi e gliricídia em sistemas tradicional e agroflorestal sob condições semiáridasResumo -O objetivo deste trabalho foi estimar as quantidades de N fixadas em feijão-caupi em sistema tradicional e em feijão-caupi e gliricídia em sistema agroflorestal, sob condições semiáridas do Nordeste brasileiro. O experimento foi conduzido em blocos ao acaso, em arranjo em parcelas subdivididas, com quatro repetições, no semiárido da Paraíba. As parcelas consistiram dos sistemas agroflorestal e tradicional (sem árvores), e as subparcelas, dos três cultivos entre as linhas das árvores, no sistema agroflorestal. Para estimar a fixação de N, amostras das plantas foram coletadas no quarto ciclo de crescimento das espécies perenes e no quarto ciclo de cultivo das espécies anuais. No sistema agroflorestal com capim-buffel e palma forrageira, a gliricídia fixa simbioticamente altas proporções de N (>50%) e adiciona quantidades maiores de N (40 kg ha -1 nas folhas) que no sistema tradicional (11 kg ha -1 nos grãos e 18 kg ha -1 na palhada). No sistema agroflorestal com milho e feijão-caupi, a gliricídia não fixa N e a adição de N é limitada à fixação no feijão-caupi (2,7 kg ha -1 ), que é menor que no sistema tradicional em razão da sua baixa produção de biomassa.Termos para indexação: Gliricidia sepium, Vigna unguiculata, fixação biológica do nitrogênio, abundância natural, 15 N.

“…Many of them are important in forestry and silvipastoral production (timber, posts, firewood, forage, etc. ), which constitute the most common land use in the region (Foroughbakhch et al 2009). During the last 350 years, extensive grazing has been practiced in these areas , resulting in the loss of both quality and quantity of forage plant species followed by a reduction in the plant layer which covers and protects the soil (Eviner & Chapin 2003, Fahring 2003).…”

Foliar biomass production and litterfall pattern of five timber species in forest plantations of semi-arid lands of the northeastern Mexico

et al. 2017

Background: Fodder shrubs and trees have both economic as well as ecological values in most extensive systems of arid and semiarid regions. Hypothesis: The litterfall represents an important way in maintaining the productivity of these ecosystems, and we hypothesized that its production pattern is related to the foliar biomass production, associated with seasons and species. Studied species: Acacia berlandieri, Acacia wrightii, Ebenopsis ebano, Havardia pallens and Helietta parvifolia. Study site and years of study: The foliar biomass was evaluated seasonally, from the dry weight of a representative branch of each species. The litterfall was collected every 15 days through litter traps installed under tree canopies, in experimental plantations of 30 years old, in the semi-arid zone of northeastern Mexico. Results: The foliar biomass values showed highly significant differences (P < 0.01) among species as well as seasons, whereas leaf litter values presented highly significant differences (P < 0.01) among seasons but not (P > 0.05) among species. The maximum foliar biomass production was registered in summer by E. ebano (9,029 kg ha ). A significant linear correlation (R 2 = 68,79 %) was determined between accumulation of leaf litter and foliar biomass production in autumn. Concluisions: As conclusion, the leaf litter pattern can be related to the foliar biomass production, depending on the seasons and species. That constitutes a practical tool for the management of the forest ecosystems in semiarid areas.

“…The cattle's ranching was practiced for 350 years in some areas of Tamaulipan scrubland from Northeastern Mexico. Long-term consequences of grazing were quality and quantity losses in forage species (Foroughbakhch et al, 2009). Currently, shrub species of the Fabaceae family, particularly A. amentacea and P. texana, are part of the dominant species of this area in Northeastern Mexico (Estrada and Jurado, 2005).…”

In order to evaluate the nutritional value of Parkinsonia texana and Acacia amentacea, two leguminosae species of the Tamaulipan scrubland, Northeastern Mexico, two experiments were carried out: the first tested the effects of season and browse species on chemical composition as nutritional variable to small ruminants; the second tested the effect of the addition of polyethylene glycol (PEG) on fermentation parameters. Foliage samples were collected from three sites. Data of chemical composition were analysed using analysis of variance for a bi-factorial arrangement, whereas the effect of PEG was analysed by a strip plot design. Results of chemical composition were affected by interacting factors season*species as individually they were significantly different (P<0.001). Addition of PEG affected (P<0.001) fermentation parameters. Significantly higher values of neutral detergent fibre (42%), condensed tannins (19%), purines (9 mol), partitioning factor (PF) (6.1) and gross energy losses (GEL=6.7%) were found in A. amentacea, while P. texana gave higher crude protein (18%), in vitro true organic matter digestibility (82%), metabolisable energy (ME) [2.1 Mcal/kg dry matter (DM)], A (183 mL), c (0.07/h) and L (0.86 h). Addition of PEG increased ME, and affected (P<0.001) fermentation parameters A and c, while purines and PF decreased. Results indicate that chemical composition and fermentation parameters vary according to seasons and species. PEG addition increases the fermentation parameters, which indicates that PEG counteracts the detrimental effects of secondary components of samples. Data suggest that using both species combined could supply necessary nutritional requirements to small ruminants in the Tamaulipan scrubland.
