Challenges and opportunities for improving N use efficiency for rice production in sub-Saharan Africa
ABSTRACT In sub-Saharan Africa (SSA), rice production from smallholder farms is
challenged because of a lack of fertilizer inputs and nutrient-poor soils. Therefore, improving …

[HTML][HTML] Thirty years of water management research for rice in sub-Saharan Africa: Achievement and perspectives
Rice is one of the major staple foods in sub-Saharan Africa (SSA) and is mainly grown in
three environments: rainfed upland and rainfed and irrigated lowlands. In all rice-growing …

Impacts of climate change on rice production in Africa and causes of simulated yield changes
This study is the first of its kind to quantify possible effects of climate change on rice
production in Africa. We simulated impacts on rice in irrigated systems (dry season and wet …

Intensifying rice production to reduce imports and land conversion in Africa
Africa produces around 60% of the rice the continent consumes, relying heavily on rice
imports to fulfill the rest of the domestic demand. Over the past 10 years, the rice-agricultural …

Greenhouse gas emissions in irrigated paddy rice as influenced by crop management practices and nitrogen fertilization rates in eastern Tanzania
In rice production greenhouse gas emission (GHG) reduction is an important task for many
countries, Tanzania included. Of global agricultural GHG emitted from rice fields, about 30 …

Variability and determinants of yields in rice production systems of West Africa
Rice (Oryza spp.) is the major staple food for most countries in West Africa, but local
production does not meet demand. Rice is grown mainly by smallholder farmers, and yields …

Yield-limiting macronutrients for rice in sub-Saharan Africa
Nutrient deficiencies are considered major constraints to rice production in sub-Saharan
Africa (SSA), but a systematic, continent-wide analysis of these constraints is lacking. The …

Rice breeding for yield under drought has selected for longer flag leaves and lower stomatal density
Direct selection for yield under drought has resulted in the release of a number of drought-
tolerant rice varieties across Asia. In this study, we characterized the physiological traits that …

Decomposing rice yield gaps into efficiency, resource and technology yield gaps in sub-Saharan Africa
Meeting current rice demand in sub-Saharan Africa (SSA) requires narrowing yield gaps on
currently available agricultural land. The objectives of this study were to decompose rice …
