Overall performances of Leucaena leucocephala and Morus alba in high-density protein banks at maturity in western Burkina Faso. Agroforestry Systems, 99:11, 11 p.

Résumé : The objective of this work was to carry out long-term monitoring of protein banks (PB) established under the real-low-input-farm conditions of Burkina Faso, characterized by a Sudano-Sahelian climate type with wide variations in rainfall. The PBs, planted in 2016–2017 with Leucaena leucocephala (LL) and Morus alba (MA) at a high density (20,000 plants/ha), were monitored from 2016/2017 to 2021 for their biomass (fodder) production, chemical composition and nutritional value of the edible fodder, and their impacts on soil carbon content. The average annual fodder production of LL for the 6 PBs (1, 2, 3, 4, 5, and 6) was 11.4 ± 2.12 t DM/ha/year, while that of MA was 3.8 ± 1.2 t DM/ha/year for the 3 PB (1, 2, and 3). Such differences are related to higher adaptive capacity for LL in such climatic conditions. Crude protein was higher in LL (19% versus 17%), but dry matter digestibility (65% versus 77%) was superior in MA. Soil carbon increased during the five monitored years, an exciting result for these poor, low-fertility soil conditions. Our results demonstrate the technical and environmental feasibility of establishing this low-input agroforestry technology in these conditions and inspire the potential of sustainable agriculture as an agroecological alternative to overcoming feed shortages for local livestock farming. However, the successful management of a PB relies on selecting the right suitable species, protecting them, and managing them during the establishment and fodder production periods with suitable cutting frequency and appropriate post-harvest management.
