The oldest record of finger millet comes from an archaeological site in Africa dating to the 3rd millennium B.C. 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

Climate requirements

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 above sea level (e.g. in the 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

''Striga'' can be controlled with limited success by hand weeding, herbicide application, crop rotations, improved soil fertility, intercropping and biological control. The most economically feasible and environmentally friendly control measure would be to develop and use ''Striga''-resistant cultivars. ''Striga'' resistant genes have not been identified yet in cultivated finger millet but could be found in crop wild relatives of finger millet.

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

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.
