Pearl millet

Characteristics

With ovoid grains of 3 – 4 mm length pearl millet has the largest kernels of all varieties of millet (not including sorghum) which can be nearly white, pale yellow, brown, grey, slate blue or purple. The 1000-seed weight can be anything from 2.5 to 14 g with a mean of 8 g.

The height of the plant ranges from 0.5 – 4 m.

Cultivation

Pearl millet is well adapted to growing areas characterized by drought, low soil fertility, and high temperature. It performs well in soils with high salinity or low pH. Because of its tolerance to difficult growing conditions, it can be grown in areas where other cereal crops, such as maize or wheat, would not survive. Pearl millet is a summer annual crop well-suited for double cropping and rotations.

Today pearl millet is grown on over 260,000 km² of land worldwide. It accounts for approximately 50% of the total world production of millets.

Common names for pearl millet

India

India is the largest producer of pearl millet. Rajasthan is the highest-producing state in India.

Africa

The second largest producer of pearl millet and the first to start cultivation,Africa has indeed been successful in bringing back this lost crop.

Sahel

Pearl millet is an important food across the Sahel region of Africa. It is a main staple (along with sorghum) in a large region of northern Nigeria, Niger, Mali and Burkina Faso. In Nigeria it is usually grown as an intercrop with sorghum and cowpea, the different growth habits, growth period and drought vulnerability of the three crops maximising total productivity and minimising the risk of total crop failure. It is often ground into a flour, rolled into large balls, parboiled, liquefied into a watery paste using fermented milk, and then consumed as a beverage. This beverage, called "fura" in Hausa, is a popular drink in northern Nigeria and southern Niger.

Namibia

In Namibia, pearl millet is locally known as "mahangu" and is grown mainly in the north of that country, where it is the staple food. In the dry, unpredictable climate of this area it grows better than alternatives such as maize.

Mahangu is usually made into a porridge called "oshifima" (or "oshithima"), or fermented to make a drink called "ontaku" or "oshikundu".

Traditionally the mahangu is pounded with heavy pieces of wood in a 'pounding area'. The floor of the pounding area is covered with a concrete-like coating made from the material of termite mounds. As a result, some sand and grit gets into the pounded mahangu, so products like oshifima are usually swallowed without chewing. After pounding, winnowing may be used to remove the chaff.

Some industrial grain processing facilities now exist, such as those operated by Namib Mills. Efforts are also being made to develop smaller scale processing using food extrusion and other methods. In a food extruder, the mahangu is milled into a paste before being forced through metal die. Products made this way include breakfast cereals, including puffed grains and porridge, pasta shapes, and "rice".

Research and development

Recently more productive varieties of pearl millet have been introduced, enabling farmers to increase production considerably.

To combat the problem of micronutrient malnutrition in Africa and Asia, a study of serving iron-biofortified pearl millets which is bred conventionally without genetic modification to a control group is proved to have higher level of iron absorbance by the group.

The most widely grown millet is pearl millet, which is an important sized crop in India and parts of Africa. Finger millet, proso millet, and foxtail millet are also important crop species. In the developed world, millets are less important. For example, in the United States the only significant crop is proso millet, which is mostly grown for bird seed.
