this study analyzed the effectiveness of cassava women processors in value addition technologies in abia state, nigeria. purposive and simple random sampling techniques were used to select ninety (90) women. data for the study were collected through a structured questionnaire and analyzed with descriptive statistics such as: frequency, mean scores and percentages and inferential statistics (tob...

Cassava polyploid breeding has drastically improved our knowledge on increasing root yield and its significant tolerance to stresses. In polyploid cassava plants, increases in DNA content highly affect cell volumes and anatomical structures. However, the mechanism of this effect is poorly understood. The purpose of the present study was to compare and validate the changes between cassava cultiv...

Neosilba perezi (romero & ruppel) is known as the cassava shoot fly or shoot fly, because, unlike other species of its genus, its larvae feed exclusively on shoots of cassava (Manihot esculenta crantz). these larvae kill the affected cassava shoots. natural parasitism by a braconid, phaenocarpa neosilba arouca & Penteado-Dias, 2006, on shoot fly larvae was studied at 3 locations in the southwes...

Every innovation is targeted towards adoption; a process which involves several levels of risks. Bio-fortified Vitamin A cassava variety is an innovation targeted not only to solve the yield of farmers but to increase the nutritional intake of Nigerian household. The research specifically seeks to investigate; the risks involved in the adoption of vitamin A cassava variety; the risk attitude of...

Cassava brown streak disease (CBSD) is arguably the most dangerous current threat to cassava, which is Africa's most important food security crop. CBSD is caused by two RNA viruses: Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV). The roles of the whitefly Bemisia tabaci (Gennadius) and farmer practices in the spread of CBSD were investigated in a set of field a...

Transposable elements contribute to the size, structure, variation, and diversity of the genome and have major effects on gene function. Sequencing projects have revealed the diversity of transposable elements in many organisms and have shown that they constitute a high percentage of the genome. PCR-based techniques using degenerate primers designed from conserved enzyme domains of transposable...

Natural microbial consortia from hot spring samples were used to developed thermophilic mixed cultures for biohydrogen production from cassava starch processing wastewater (CSPW). Significant hydrogen production potentials were obtained from three thermophilic mixedculturesnamelyPK,SWandPRwithmaximumhydrogenproductionyieldsof249.3, 180 and 124.9 mL H2/g starch, respectively from raw cassava sta...

Cassava (Manihot esculenta) is the most important root crop in the tropics, but rapid postharvest physiological deterioration (PPD) of the root is a major constraint to commercial cassava production. We established a reliable method for image-based PPD symptom quantification and used label-free quantitative proteomics to generate an extensive cassava root and PPD proteome. Over 2600 unique prot...

Early storage root bulking (ESRB) in cassava has increasingly become important in the national cassava breeding programmes in Africa. To assess farmers' perceptions on ESRB in cassava and identify their cultivar selection criteria, a study was conducted in east and central Uganda. One hundred and twenty cassava farmers were sampled and interviewed following structured questionnaires, and their ...

In Mozambique, epidemics of the cassava-associated paralytic disease, konzo, have been reported in association with drought or war: over 1100 cases in 1981, over 600 cases in 1992-1993, and over 100 cases in 2005. Smaller epidemics and sporadic cases have also been reported. Large epidemics have occurred at times of agricultural crisis, during the cassava harvest, when the population has been d...
