Mountain ecosystems are almost all in a state of advanced degradation due to human pressure: deforestation, inadequate plowing on steep slopes. The classification of slopes in the mountains of Tessala reveals a rather undulating topography, frequently above 25%. In order to meet the needs of farmers and predict harvests. This study, based on the results of surveys carried out on farmers’ fields and in the mountainous region of Tessala, describes the effect of the slope on the morpho-physiological parameters of the barley crop at three sites in the zone study. The results obtained from this study of the influence of the slope on the yield of the barley crop show that the soils with a steep slope have a negative effect on the behavior of the crops and their morphological parameters (height of plant, spike length, weight of spikes)  and performance component (Number of grains/spike, weight of grain/spike, number of grains/m², weight of one thousand grains). The results obtained suggest the importance of adequate and rigorous choice of land in any development strategy in the study area where the terrain is particularly pronounced and sloping land (+ 12%) occupies almost 51% of the land area.
