In Ethiopia almost 10 million people are dependent on ensete (Ensete uentricosum (Welw) Cheesman), also known as 'false banana'. In the Gurage area in Central Ethiopia, agronomic and nutritional aspects of ensete were studied in 60 households in six villages. Ensete is propagated vegetatively and has a 6-year growing cycle during which it is transplanted three or four times. Men harvest the plants; women scrape the pseudo stem in order to separate the starchy pulp from the fibre, and pulverise the corm. The pulp is fermented and stored for up to 5-7 years in earthen pits. The yield of ensete food (ko'cho) was found to be 34 kg per plant or 9.5 tons ha-' per year. Compared with other foods grown in Ethiopia, the energy yield of ensete (6.1 MJ m-' per year) was higher than that of all cereals, Irish potato, sweet potato and banana, but lower than that of cassava. The protein yield of ensete was higher (1 1.4 g m-' per year) than all of the crops mentioned above, except for banana and Irish potato. To make ensete bread, fermented pulp is squeezed to make it drier, chopped to shorten the fibres and a 2 cm layer is baked for 15 min. Unfermented freshly harvested corm is also eaten after boiling. All foods have a low protein content (4-22 g kg-I). Bu'lla, white desiccated juice collected from the pulp, is more energy rich (8.5 MJ kg-') than ko'cho (6.5 MJ kg-'). A dietary survey, conducted in 39 households comprising 237 persons, showed that the average daily intake of 0.55 kg ensete provided 68% of total energy intake, 20% of protein, 28% of iron but no vitamin A. Energy intake from all food consumed was very low, being only 60% of requirements, while protein intake at 107% was ample. Since ensete can be stored for years, is readily available throughout the year and can withstand dry periods, its cultivation can significantly improve household food security in highland areas prone to drought and famine.
