1 paź 2021 · The eastern wave has pearl millet cultivation dating from at least 2000 BCE, deriving from the Tilemsi Valley, a remaining Saharan water channel at a time of increasing desiccation (Manning and Fuller, 2014). Millet cultivation spread south of the Niger river bend into the Douentza region shortly thereafter (MacDonald et al., 2017). The western ...
Pearl millet (Cenchrus americanus, commonly known as the synonym Pennisetum glaucum) is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The center of diversity, and suggested area of domestication, for the crop is in the Sahel zone of West Africa. [2] Recent archaeobotanical ...
24 lis 2023 · This review shows that increased temperature has a negative impact on millet yield and growth parameters. Other climatic factors significantly affecting millet production in the Central Sahel include drought, desertification, dry spells, rainfall variability, and wind.
The Sahel is home to cowpeas, pigeon peas, groundnut, green grams and chick peas but millet and sorghum are the two most vital food crops of the Sahel. Millet is a group of annual grasses that are mainly found in arid or semi-arid regions in the world, normally found growing in places that barley and wheat are unable to thrive.
The markets of the Sahel, made possible by the surplus production of hardy dryland grains such as millet, provided the site of convergence for all these varied goods. Western Africa from the 1st to the 15th century was shaped by the mutually beneficial exchange of goods gathered or produced in the different ecoclimatic zones.
10 lis 2018 · Both domesticated cereals, pearl millet and sorghum, appear to have been grown together in the far eastern Sahel, certainly by the start of the second millennium BC (Mahal Teglinos) and possibly even earlier (Shaqadud Cave?), prior to being transferred to India via emerging Arabian Sea maritime connections.
We found that the high spatial variability of millet yield is due to two main edaphic factors: soil fertility properties and water availability. It is still unknown whether the spatial variability of the two main factors is inherent to Sahelian soils.
