Abstract: the Guinea –savannah of the Adamawa region of Cameroon, a study was carried out to see the effect of organic manure, mycorrhizae and chemical fertilizer on the growth performance of Jatropha curcas in the locality of Dang (Ngaoundere). The experimental design was a split plot with two factors, the first being the origin or accession at two levels (Chad and Cameroon), the second being 4 treatments (organic manure, mycorrhizae, positive control=chemical fertilizer (NPK-20 10 10) and negative control) in three replicates. Data was collected on growth parameters as influenced by the different treatments, total biomass yields, carbon sequestration and root mycorrhizal colonization. Results indicate that fertilizers used have a highly significant effect (P <0.001) on the growth, development and dry biomass produced at 180 days after sowing, as well as on the level of carbon sequestration. Accessions of local origin (Cameroon) adapted well in the Ngaoundere environment. Organic manure was the most effective in the improvement of growth and development of plants, followed by chemical fertilizers and mycorrhizae. Chemical fertilizer had a negative effect on root mycorrhizal colonization. Organic fertilizers followed by mycorrhizae are seemingly advantageous for the promotion of Jatropha curcas cultivation in the Ngaoundere locality |
