Postharvest physiological deterioration (PPD) is an unresolved major stress in cassava (Manihot esculenta Crantz), which constrains the crop suitability for commercial and industrial purposes. The present study sourced for PPD tolerance from different genetic resources available within a cassava ...

Late root bulking is a major factor leading to rejection and abandoning of improved cassava genotypes in sub-Saharan Africa. Early bulking (EB) varieties shorten the growth period from planting to harvesting, better fit into environments with short rainy season, and reduce exposure to biotic and ...

New seed yam systems from minisetts, minitubers and vine cuttings have been developed for yam production to supplant the traditional systems, which have proven inefficient and costly. The new techniques provide producers in tropical countries with the opportunity to minimize production costs, red...

The unavailability of good quality seed yams (Dioscorea rotundata Poir) is frequently cited to be responsible for the slow rate of growth or decline in yam production. Current production and storage practices, as well as quality of seed yams in 35 villages of Oyo North, Asaba, Lokoja, and Lafia a...

Tuber of most varieties of white Guinea yam, Dioscorea rotundata Poir., produce a single sprout in the proximal region after the break dormancy. The location and pattern of sprout formation on intact tubers of a multiple sprouting variety, Pepa were studied. Only 0.4% of the tubers had a single s...

The overall system for supplying plantable stems of improved cassava varieties from the International Institute of Tropical Agriculture (IITA) was surveyed for Oyo State where IITA is situated. This study examined the relation of spread of adoption of these varieties during the period of 1976 thr...
