African cereal demand and supply analysis: Past trends and future prospect
Africa per capita cereal harvesting land cereal yield
2011/1/12
For the past four decades there has been an overwhelming dependence on cereals for daily direct human food energy in Africa. Most of these demands were largely met through domestic production, althoug...
Interspecific Differences in the Mechanism of Drought Tolerance among Four Cereal Crops
Drought tolerance Interspecific difference Japanese millet Maize Osmotic adjustment Pearl millet Sorghum Water stress
2009/8/4
Interspecific differences in drought tolerance were studied by two solution- and one field-culture experiments in a glasshouse using Japanese millet, sorghum, pearl millet and maize. Water stress trea...
