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).
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 ...
10 lis 2018 · Pennisetum glaucum may have been undergoing domestication shortly thereafter in the western Sahel, as finds of fully domesticated pearl millet are present in southeastern Mali by the second half of the third millennium BC, and present in eastern Sudan by the early second millennium BC.
If today the Sahel appears to be at the margins of the flow of goods shipped in and out of ports along the Atlantic coast, for over two millennia the Sahel was effectively the “coast” of the Sahara and its cities major “ports” in the trans-Saharan trade.
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.
1 lut 2022 · In 2015, the total rainfall was 373 mm (22 days of rain) in the Sahel zone compare to 973 mm (54 days of rain) in the Sudan zone. This clearly explains why farmer in the Sahel zone prefer early maturing varieties and they systematically reject late maturing pearl millet varieties.
We found that the high spatial vari-ability of millet yield is due to two main edaphic factors: soil fertility properties and water availability. It is still unknown whether the...
