— Inefficient and unbalanced use of fertilizer is some of the plausible reasons contributing to the significant cassava yield gaps in Sub-Saharan Africa. However, there is limited research regarding the responses of cassava to organic and inorganic fertilizers used in these agrological settings. We conducted a study in the Pissa areas with the participation of members of an agropastoral group to improve the cassava yield in rural areas of the Central African Republic. The experimental layout was a randomized complete block design (RCBD) with four treatments replicated four times and comprising 16 elementary plots of 25m² (5m by 5m). The treatments were randomly assigned from 1 to 4 (T1, T2, T3, and T4). According to the treatments, the variabilities between cassava's growth, yield, and economic productivity in pure culture were measured and quantified. The data were subjected to Analysis of Variance (ANOVA) using a linear model of R statistical software version 3.1.2. We performed Principal Component Analysis (PCA) on several parameters. This study shows that treatments T4 (cassava + NPK + cow manure) and T3 (cassava + NPK) resulted in plants that have better growth in heights and diameters, unlike T1 (control) and T2 (peasant practice), which have the lowest values. The PCA confirmed that the variability between the treatments is up to 52.12% on the two axes (1 and 2) and affirms that the yields obtained during the study show a highly significant difference. The treatment T4 (cassava + NPK + cow manure) gave the highest yield and generated a good profit compared to other treatments. There was no correlation between treatments in terms of growth and productivity parameters. The T4 treatment proposed by the International Atomic Energy Agency (IAEA) performed better on all the evaluations. Therefore, organo-mineral fertilization can contribute to the improvement of cassava production. |
