Title : Effect of different cropping associations based on maize legumes and mineral fertilizers on the productivity of manihot esculenta crantz in the forest zone (commune of pissa) central african republic


The objective of the study, conducted under integrated management in a forest zone with the participation of members of an agro-pastoral group, is to improve the agricultural yield of cassava in rural Central Africa. The design chosen for this work is a completely randomized block design (BCR) with sixteen treatments (from 0 to 15) and four random replications, comprising 64 elementary plots of 25m². The variabilities between the growth and yield parameters are evaluated. The software ® version 4.0.3 and XLSTAT 2016 version 4.2.1 were used to analyze the data. Analyses of variance (ANOVA) and Principal Component Analysis (PCA) were used to discriminate between parameters consistent with the treatments. Treatments T13 (cassava + groundnut + NPK), and T9 (cassava + cowpea + PK) have plants with better growth in height and diameter. A weak linear correlation was observed between plant diameters and heights. Principal component analysis (PCA) confirmed that fresh root yields showed a highly significant difference; T13 (cassava +arachid +NPK) gave the highest yield compared to the other treatments. The T13 treatment proposed by the International Atomic Energy Agency (IAEA) showed better performance on all evaluations. Mineral fertilization associated with legumes can contribute to the improvement of cassava production.

Key words : Cassava, Fertilizers, Yield, Peanut, cowpea.

What will audience learn from your presentation?
This study provides results that can be built upon by other researchers in helping farmers improve their practices to enhance cassava production. The results are technical and can be applied to solve the problem of cassava food in producing countries and will improve the economic situation of the producers.


Ephrem Kosh-Komba is a full professor of plant biology. He did his thesis and Developmental Biology, option: Agronomic Sciences at the Faculty of Sciences of the University of Lome (Togo) in collaboration with CIRAD in Montpellier, France. He is currently a lecturer at CAMES and is in charge of a project for the restoration of soil fertility for agriculture in the Central African Republic. He is also the counterpart of a regional project (RAF 5081) on soil fertility for cassava production.
