Proceedings...  aCassava is one of the most useful plants around the equator with a crop area of about 14 million ha. Because of its high yield potential and needs that it meets locally, a further expansion of cassava utilization is expected. The methods of cultivation, harvesting, and processing barely meets the demands of the market and teh developing industry. The Institute of Tropical Agriculture in Leipzig started in the early 1980s to search for technical solutions to difficulties in cassava harvest. As a result of its activities, a machine has been developed, which goes under the cluster of roots, raises them up, and lays them down on the soil surface. The above ground plant part is cut off at a height of about 30 cm before the machine enters the plot to harvest roots. Such harvesting machines are efficient; they prevent root damage and meet other demands for effective harvesting operations.  aAlimentação  aColheita  aConsumo  aManihot Esculenta  aCongresso1 aMAHNERT, E.1 aNEUMANN, R.  tWageninger, Netherlands: ISTRC, 1994.
