Intercropping cassava (Manihot esculenta Crantz) and maize (Zea mays L.) can alleviate weed problems. The weeds which might otherwise build up before cassava covers the ground can be replaced by the cereal. The objective of this study was to determine effects of intercropping and fertilizer appli...

The distribution of the cyanogenic potential in cassava germplasm has been found to be a continuum from very low values to high levels. Within the same genotype, the cyanogenic potential is affected by the planting season; it is low when planted at the beginning of the rainy season, and high when...

Field experiments were conducted at Ibadan and Bida in Nigeria, west Africa, to investigate the effect of mound height and cassava cultivar on cassava performance (tuber yield, top yield, tuber length, and plant height). In the Ibadan site, where the soil surface become waterlogged before cassava...

Multilocational trials were conducted in several agroecological zones in West Africa to assess the magnitude of genotype x environment (G x E) interaction and to identify stable varieties which could be used in breeding programs in the region. The reaction of the varieties to major cassava diseas...
