It was claimed to have been found in an Indian archaeological site dated to 1800 BCE (Late Bronze Age); however, this was subsequently demonstrated to be incorrectly identified cleaned grains of hulled millets. The oldest record of finger millet comes from an archaeological site in Africa dating to the 8th century AD. By 1996, cultivation of finger millet in Africa was declining rapidly because of the large amount of labor it required, with farmers preferring to grow nutritionally-inferior but less labor-intensive crops such as

Taxonomy and botanical description of finger millet

There are ten species under the genus ''Eleusine'' Gaertn, seven diploid (2n=16, 18 and 20) and three tetraploid taxa (2n=36 or 38). Eleusine a''fricana'' (Kenn.-O'Bryne), ''Eleusine coracana'' (L.) Gaertn, ''Eleusine floccifolia'' (Spreng), ''Eleusine indica'' (L.) ''Gaertn'', ''Eleusine intermedia'' (Chiov.) (S.M.Phillips), ''Eleusine jaegeri'' (Pilg.), ''Eleusine kigeziensis'' (S.M.Phillips), ''Eleusine multiflora'' (Hochst. ex A.Rich), ''Eleusine'' ''semisterilis'' (S.M.Phillips) and ''Eleusine tristachya'' (Lam.) Lam''.'' Different studies confirmed that ''Eleusine coracana'' was originated from ''E. indica'' and ''E. floccifolia'' genomes and selected for cultivation from its wild type ''E. Africana.''

Finger millet is a short-day plant with a growing optimum 12 hours of daylight for most varieties. Its main growing area ranges from 20°N to 20°S, meaning mainly the semiarid to arid tropics. Nevertheless, finger millet is found to be grown at 30°N in the

, it prefers moderate rainfall ( annually). The majority of worldwide finger millet farmers grow it rainfed, although yields often can be significantly improved when irrigation is applied. In India, finger millet is a typical'' rabi'' (dry-winter season) crop. Heat tolerance of finger millet is high. For Ugandan finger millet varieties, for instance, the optimal average growth temperature ranges at about 27 °C, while the minimal temperatures should not be lower than 18 °C. Relative to other species (pearl millet and sorghum), finger millet has a higher tolerance to cool temperatures. It is grown from about 500 to about 2400 m above sea level (e.g. in Himalaya region). Hence, it can be cultivated on higher elevations than most tropical crops. Finger millet can grow on various soils, including highly weathered tropical

This makes finger millet a weak competitor for light, water, and nutrients compared with weeds. In East and Southern Africa, the closely related species ''

Finger millet blast can also infest finger millet weeds such as the closely related ''E. indica'', ''E. africana'', '' Digitaria ''spp., '' Setaria'' spp., and '' Doctylocterium spp''. Finger millet blast can be controlled with cultural measures, chemical treatments, and the use of resistant varieties. Researchers in Kenya have screened wild relatives of finger millet and landraces for resistance to blast. Cultural measures to control finger millet blast suggested by ICRISAT for Eastern Africa include crop rotations with nonhost crops such as

Insects

The pink stem borer ('' Sesamia inferens'') and the finger millet shoot fly ('' Atherigona miliaceae'') are considered as the most relevant insect pests in finger millet cultivation.

Propagation and sowing

Propagation in finger millet farming is done mainly by seeds. In rainfed cropping, four sowing methods are used: *Broadcasting: Seeds are directly sown in the field. This is the common method because it is the easiest way and no special machinery is required. The organic weed management with this method is a problem, because it is difficult to distinguish between weed and crop. *Line Sowing: Improved sowing compared to broadcasting. Facilitates organic weed management due to better distinction of weed and crop. In this method, spacing of 22 cm to 30 cm between lines and 8 cm to 10 cm within lines should be maintained. The seeds should be sown about 3 cm deep in the soil. *Drilling in rows: Seeds are sown directly in the untreated soil by using a direct-seed drill. This method is used in conservation agriculture. *Transplanting the seedlings: Raising the seedlings in nursery beds and transplant to the main field. Leveling and watering of beds is required during transplanting. Seedlings with 4 weeks age should be transplanted in the field. For early Rabi and Kharif season, seedlings should be transplanted at 25 cm x 10 cm and for late Kharif season at 30 cm x 10 cm. Planting should be done 3 cm depth in the soil

Harvest

A handful of hope in Gulu, northern Uganda (6721454911)

Crop does not mature uniformly and hence the harvest is to be taken up in two stages. When the earhead on the main shoot and 50% of the earheads on the crop turn brown, the crop is ready for the first harvest. At the first harvest, all earheads that have turned brown should be cut. After this drying, threshing and cleaning the grains by winnowing. The second harvest is around seven days after the first. All earheads, including the green ones, should be cut. The grains should then be cured to obtain maturity by heaping the harvested earheads in shade for one day without drying, so that the humidity and temperature increase and the grains get cured. After this drying, threshing and cleaning as after the first harvesting.

. Furthermore, the delicate seed can get crushed during the milling. The development of commercial mechanical milling systems for finger millet is challenging. Therefore, the main product of finger millet is whole grain flour. This has disadvantages, such as reduced storage time of the flour due to the high oil content. Furthermore, the industrial use of whole grain finger millet flour is limited. Moistening the millet seeds prior to grinding helps to remove the bran mechanically without causing damage to the rest of the seed. The mini millet mill can also be used to process other grains such as
