ABSTRACT

An assessment of the performance of the Bongor rice-growing area in the Mayo-Kebbi East province of Chad over two growing seasons (dry season and rainy season) was conducted in 2025. Three methods were used: soil surveys and analysis to assess the fertility level of plot B, diagnostic analysis based on farmers’ perceptions within the plot, and finally, evaluation of performance indicators for plot B based on a set of indicators derived from the diagnostic phase. The results show that upon its creation in 1964, the area used technical guidelines disseminated by the National Office for Rural Development (ONDR) under the supervision of Chinese cooperation. Thus, the judicious use of fertilizers and pesticides, irrigation management, and the introduction of high-yield fertilizers have enabled agricultural yields to reach up to 8 t/ha in 1978, compared to 4 t/ha in 2024. Soil analyses confirm a deficiency in phosphorus (P < 30 ppm) and nitrogen (N < 5%). The high average C/N ratio (13) suggests low organic matter mineralization in these soils and necessitates corrective action to increase mineral nutrient uptake.

KEYWORDS
