Analysis of relationships between production of yam [Dioscorea spp.] and its determinants in Nigeria: a cointegration approach
Understanding the resource allocation and use efficiency is essential considering the supportive role of agriculture in the advancement of other productive sectors of the economy. Technical efficiency and its determinants were investigated among smallholder cassava-farming and decision-taking uni...

Efficiency and its determinants among smallholder farming units supplying cassava to commercial starch processors in Nigeria: data envelopment analysis approach
An analysis was conducted of the productivity of smallholder farmers enrolled into an out-growers’ scheme to supply cassava to commercial starch processors under the Nestlé-IITA cassava starch value chain project. Under the project, improved cassava varieties–cloned to be high-yielding, early mat...

The browse shrub Gliricidia sepium, introduced into the subhumid zone of Nigeria to serve as a supplementary-forage source for ruminant during the dry season, has the undesirable characteristic of shedding its leaves during its flowering phase which coincides with the early dry season. This repor...

In Nigeria, researcher-managed and farmer-managed West African Dwarf goats were grazed on Stylosanthes hamata (stylo) fodder banks at stocking rates of 29, 43 and 57 goats/ha and 22-25, 42-43, 50-55 and 68-92 goats/ha, respectively. Extrusa samples were taken from oesophageally fistulated goats t...

The dry matter yield, nutritive value and persistence of three legume species (Stylosanthes hamata Taub., S. capitata Vog. and Centrosema pascuorum Mart. ex. Benth.) cut at different frequencies during the growing season or only once at the end of the growing season were compared. The shorter cut...

Investigations were conducted into the development characteristics and influence of stage of pod development on seed viability of Gliricidia sepium. The influence of sowing depth on seedling emergence of the first and last harvests was also investigated. Pods were harvested over three periods - 5...

Cassava is an important food security crop among smallholder farmers in Southern Nigeria, because it can tolerate drought, low soil fertility and its production requires minimum external inputs. In most African countries, cassava is becoming important cash crop that has high potential for use as ...
