MACHADO, F.A. et al. Production and quality of litter of three leguminous tree native of the northeastern Brazil. Arch. zootec. [online]. 2012, vol.61, n.235, pp.323-334. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922012000300001.

The objective of this work was to study the production and litter quality of three native trees legumes of northeast of Brazil, the faveira (Parkia platycephala Benth.), the pau-ferro (Caesalpinea ferrea Mart. ex Tul.) and bordão-de-velho (Samanea saman (Jack.)Merr.) aiming the inclusion of these species in silvipastoral systems. Samples were taken from material deposited in collectors installed under the canopy of individuals; the samples were separates in folioles, miscellaneous and pods. The average productions were: bordãode-velho, 542; faveira, 311 and pau-ferro, 594 g/m². The three species presented seasonal production, with the bordão-de-velho concentrating the production in August, the faveira from July to October, and the pau-ferro from April to August. The P contents in the three species had been low, with exceptions for pods of bordão-develho (0.21%) and miscellaneus and pods of pau-ferro (0.14 and 0.16%, respectively). The contents of K varied from 0.16%, in miscellaneus of faveira to 0.65% in pods of the bordão-de-velho. The contents of N varied from 0.85%, in miscellaneus of faveira to 2.13% in folioles of bordão-de-velho. The three species showed potential for soil conservation through the deposition of its litter, and for integration in silvipastoral systems.
