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...

CIAT has developed a new intercropping technology (cassava/grain legume associations) that tries to solve the numerous problems that arise in traditional intercropping systems. High-yielding cassava cv. with an erect, late-branching growth habit are recommended to minimize intercrop competition. ...
The different alternatives for disease control in cassava, reported as efficient and that could be taken into account when designing technological packages for cassava production, are summarized. These are cultu-ral control (crop rotation, planting on furrows, elimination of crop resi-dues, dista...
The low cassava yields obtained in L.A. at present are the result of a complex of problems: 1) deficient quality of planting material, which results in low sprouting, poor rooting and little initial vigor; 2) inadequate land preparation and planting systems; 3) control systems for pests and disea...

Nigeria is presently the largest cassava producing country in the world. Cassava production is primarily at the smallholder level relying heavily on the hoe and cutlass and driven by human physical effort. Agricultural farm labour is a critical factor as Nigeria strives to utilise cassava as an i...
