Ummbila is said to have been introduced to Africa by early explorers and traders and it has been in cultivation in southern Africa perhaps since 1500 AD. The plant originated in Central America, but the exact relationship between the cultivated crop and putative ancestral species is not clear. … Ummbila is less drought resistant than uphoko and amabele but under favourable conditions will produce much larger crops. It is not prone to bird damage, so that harvesting can be done at any time, once the crop is ripe. Yields of eight tons or more per hectare can be expected under optimum conditions of moisture and nutrition.“Ummbila is for food, amabele is for beer”. The grains are pounded or ground and then cooked or boiled. It is used for porridge or for numerous other dishes. For human use in South Africa ummbila omhlope (white maize) is far more popular than isangalane (yellow maize). Unripe cobs are delicious when boiled or roasted and are commonly sold along roadsides in both green (fresh) or roasted form. Ummbila is similar to other cereals in energy value, but is somewhat less nutritious because of lower levels of essential animo acids, particularly lysine and tryptophane. PEOPLE’S PLANTS (16)
