The objective of this study is to determine the perception of corn producers on soil quality based on sustainable land management practices in the Okpara watershed. To do this, 280 heads of maize producers were surveyed in the municipalities of Pèrèrè, N’Dali, Tchaourou and Ouessè. The Fisher test made it possible to compare the soil quality score according to the municipalities, the farming practices of the Okpara watershed; the score of soil types according to farming practices and municipalities. This test showed that the municipalities of Pèrèrè and N’Dali have better soil quality scores than the municipalities of Tchaourou and Ouessè regardless of the type of soil. Multiple linear regression has shown that factors such as: the probability of predicting improved seed practices, the probability of ridging practices, the municipality of Tchaourou, the municipality of Ouessè, and the number of years of experience in agriculture in general significantly determine the quality of the soil in the Okpara watershed. Thus, it is therefore necessary to take into account the endogenous knowledge available to producers in the study area for a better assessment of the quality of the soil in future studies.
