| Summary: | Land Suitability and Risk of Erosion of an Andosol with Irrigated Garden Peas (Pisum sativum) in Western Highlands of Cameroon. In order to help increase the productivity of Pisum sativum (garden peas) as green beans and to minimize soil degradation, a trial was carried out on irrigated farms in the western highlands of Cameroon during the off - season (January - March). This study showed that : An andosol at an altitude of 1285 m cultivated with large ridges at 2 % slope was moderately suitable for this irrigated crop from November to March. However, the crop cycle between November and January would be preferable so as to take advantage of the last rains. Erosion measured under three cultural systems (terraces, large and small ridges) indicated that the magnitude was comparable and acceptable between terraces and large ridges while that of small ridges was considerably higher. These results indicate that, the large ridges perpendicular to the slope, commonly used by the local farmers of the area, are not necessarily inferior to terraces and small ridges which were considered for introduction in the irrigation of this crop.
