In this study, some engineering properties of cassava tuber samples were determined experimentally under five moisture content levels of 70 %, 65 %, 60%, 55 %, and 50 %wet basis. The properties measured were tensile strength, compressive strength and elasticity. Three experimental tools were desi...
Management of harvested (senescent) banana pseudostems has implications for efficiency of nutrient use for sole cropped as well as intercropped bananas. Two studies were conducted on aspects of nutrient flows from senescent pseudostems. Sixty one and 55% of the initial N and P, respectively, in s...

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...

The herbicides dalapon, glyphosate, paraquat, MSMA, and diuron were evaluated for their postemergence selectivity in cassava (Manihot esculenta Crantz). Four methods of application were also tested: with a shield, directed without a shield, and hitting the lower 25 or 50 percent of the plant. In ...

This study examined the dynamics of fresh yam tuber prices and applied a hedonic pricing model to estimate the market values of tuber characteristics in two consumption centers in Togo. Real prices were modeled as a function of variables measuring yam species, physical attributes of tuber, origin...

Effect of time of harvest of yam tubers on selected food quality characteristics was investigated to determine when yam tuber is due for harvesting. Setts from five land race varieties of white yam (Dioscorea rotundata) at their post-dormant stage were planted at the beginning of the rainy season...

Seed viability and emergence is one of the most important problems affecting soybean production in West Africa. Results from the multi-location yield trials indicated that introduced cultivars such as Bossier, Jupiter and Improved Pelican showed excellent adaptation and high yields provided seedl...
