Abstract: One of the national agricultural priorities is rice cultivation which is more and more attracting
Beninese government attention and private economic operators, at the same time as it is a driving
force for structuring the rural environment. The present study is interested in the production of
lowland rice in relation to development in the municipality of Adja-Ouèrè in Benin. The data
used here are inter alia the agricultural statistics relating to the evolution of the area sown, the
yields and the production of rice, the climatological data (rains and temperatures on a monthly
and / or annual scale) of the agro-agricultural station. Pobè climatology, socio-economic
information and on rice production systems collected from stakeholders during fieldwork. These
different data are subject to processing using the descriptive statistics method. Likewise, the
Economic Profitability Analysis of rice production was made. An analysis of the results shows
that the municipality of Adja-Ouèrè has enormous physical potential for the production of
lowland rice. The yield of lowland rice has changed in the municipality of Adja-Ouèrè in recent
years, going from 2,500 kg / ha in 2009 to 7,500 kg / ha in 2017, i.e. an increase in productivity
of 158.52%. In fact, the production system generates a gross margin of CFAF 303,250 / ha. The
average return on capital is therefore around 161%. Thus, 100 francs invested in the production
of rice in the commune generate an income of 161 francs for a production cycle of five months.
Rice production in the municipality of Adja-Ouèrè therefore appears profitable. But for the
sustainability of these achievements a reorganization of the rice sector is essential
