We determined the structures of Nod factors produced by six different Bradyrhizobium sp. strains nodulating the legume tree Acacia albida (syn. Faidherbia albida). Compounds from all strains were found to be similar, i.e., O-carbamoylated and substituted by an often sulfated methyl fucose and different from compounds produced by Rhizobium-Mesorhizobium-Sinorhizobium strains nodulating other spe...

This study aimed to investigate the Guddiri people’s belief system in unusual phenology, agroforestry function, medicinal value, environmental protection, and weird function of Apple-Ring Tree (Faidherbia albida) as a measure their scientific literacy. Faidherbia albida is type tree species that thrives very well, specifically Sudan Sahel Savannah Northern Nigeria. The design was descriptive su...

On fertile alluvial soils on the lakeshore plain of Malawi, maize (Zea mays L.) yields beneath canopies of large F aidherbia albida (syn Acacia albida) trees greatly exceed those found beyond tree canopies, yet there is little difference in soil nutrients or organic matter. To investigate the possibility that soil nutrient dynamics contribute to increased maize yields, this study focused on the...

Trees within farmers’ fields can enhance systems’ longer-term productivity, for example, via nutrient amelioration, which is indispensable to attain sustainable agroecosystems. While arbuscular mycorrhizal fungi (AMF) are known improve plant access soil nutrients, the potential of AMF mediate uptake tree-derived nitrogen (N) by crops from beyond crops’ rooting zones unclear. We hypothesized tha...

DNA-DNA hybridizations were performed between Bradyrhizobium strains, isolated mainly from Faidherbia albida and Aeschynomene species, as well as Bradyrhizobium reference strains. Results indicated that the genus Bradyrhizobium consists of at least 11 genospecies, I to XI. The genospecies formed four subgeneric groups that were more closely related to each other (>40% DNA hybridization) than to...

Multi-purpose Faidherbia albida trees represent a vital component of agroforestry parklands in West Africa as they provide resources (fodder for livestock, fruits and firewood) support water lifting nutrient recycling cropping. are characterized by their inverse phenology, growing leaf flowers pods during the dry season, thereby providing fodder shedding leaves wet which minimizes competition w...
