The mechanization of field operations like seeding, spraying and harvesting in continuous zero-tillage may lead to a severe compaction of the surface layer of coarse textured tropical soils, especially when mulch is sparse or missing. Therefore, a 2 year (1982–1984) field experiment was initiated...
The long‐term effects of land clearing methods (manual, shear blade, tree‐pusher/root‐rake combination, traditional), tillage systems (disc ploughing, mechanized no‐tillage, traditional) and cropping systems (annual cropping, alley cropping, graxed pasture) on surface soil physical and chemical p...
The effects of three seedbed preparation methods: mounds, minimum (handhoe) tillage and zero tillage; and two residue management methods: application of 4 Mg ha- ' of rice straw mulch and no mulch on soil physical properties and yield of cowpea ( Vigna unguiculata (L.) Walp.) were studied in a ri...
Cassava is traditionally grown on tilled soils. Interest in reduced-tillage systems is increasing in the humid tropics due to erosion problems. A field study was conducted on a sandy clay loam Ultisol to compare cassava performance in three tillage systems effects on soil water and organic carbon...
Land use and management affects runoff and soil loss from a catchment. The present study investigated the effects of land use on runoff and suspended sediment concentration and yield in the northwestern Ethiopia. We selected two small catchments: cultivated land and grassland dominated catchments...
Since 1987 cassava agronomy research has been conducted by scientists from national cassava programs in Asia in collaboration and with small financial assistance from the CIAT cassava program. This paper summarizes and pulls together the results obtained, mainly corresponding to the period of 149...
In Democratic Republic of Congo (DRC), cassava covers more than half of the area under cultivation and is permanently consumed by more than 70% of the population for its roots and about 80% for its leaves, which are one of the main vegetables in the country. National cassava production suffered a...
