Rice production by smallholder farmers in the savannas of Nigeria is constrained by weed competition. A field study was conducted to assess the effect of weed competition on the performance of upland rice varieties in 2005 and 2006 in the northern Guinea and Sudan savannas of Nigeria. The experim...

Reducing greenhouse gas (GHG) emissions from agriculture is needed to meet global climate policy targets. A number of low-emission development (LED) options exist in agriculture, which globally emits 10–12% of GHG emissions. In paddy rice production, alternative wetting and drying (AWD) can reduc...

With the aim to find new sources of resistance to rice hoja blanca (white leaf) disease, transmitted by the insect Tagosodes orizicolus, 660 genotypes were evaluated under greenhouse and field conditions. Seven resistant genotypes were identified, and genomic studies were performed to demonstrate...

The influence of underlying hydrology and overhead irrigation on plant parasitic nematode populations in upland and hydromorphic rice was examined during three successive seasons on a valley slope at the West Africa Rice Development Association station, Côte d’Ivoire. Nematode population densitie...
