Influence of altitudes on the cultural and morphological variation of Colletotrichum kahawae isolates, the causal agent of coffee berry disease in the West Region of Cameroon
Coffee berry disease (CBD) caused by Colletotrichum kahawae, is the main disease that affects arabica coffee production in Africa. Isolates of C. kahawae were collected from different altitude in the West Region of Cameroon and characterised for cultural and morphological variations. The results showed a significant variation among C. kahawae isolates related to their morpho-cultural features with respect to altitude....

Farmers’ perceptions of fertilizer micro-dosing adoption and continued use in Burkina Faso
This study analyzes fertilizer micro-dosing adoption and focuses on farmers' perceptions. Data used are from households selected based on agroecological characteristics. The bivariate probit model estimation results show that fertilizer microdosing adoption is a process. After the first adoption, 22.67% of farmers continued to apply fertilizer micro-dosing compared to 33.25% who discontinued. In addition, analysis...

Cassava use in southern Benin: Importance and perception of actors involved in the value chain
In Benin, many families resort not only to consumption but also to the therapeutic use of cassava (Manihot esculenta). The study assessed the impact of socio-economic factors on the use of cassava, and the perception of the actors involved in the value chain in Benin. Four areas of high production and processing, with 516 producers and processors of cassava roots were surveyed. The results reveal that...

Study of the combined effect of sowing date and sowing method on vegetative development of new rice paddy (Oryza sativa) varieties in Senegal River Valley under low temperatures
Rice paddy cultivation in Senegal is subject to climatic fluctuations that affect its vegetative development. Although climatic conditions are a concern, we hypothesized that the new rice paddy ISRIZ would be better adapted to these fluctuations and would allow double cropping. We studied the vegetative behavior according to the date and mode sowing under low temperatures. An experiment was carried out in a split-split...

Differences in smallholder farmers’ compost pits in terms of production and quality across Burkina Faso: The case of Eastern Region
Sub Saharan African soils have low organic matter contents, hence applying compost is therefore instrumental to improve their fertility. This study investigated the quantity and the quality of compost produced by smallholder farmers in five provinces (Gnagna, Gourma, Komondjari, Kompienga and Tapoa) from Eastern Burkina Faso. Compost quality was determined by the main physical and chemical characteristics including bulk...

Variation of some growth, agronomical and biochemical parameters of Vigna unguiculata (L. Walp) under salinity stress
The variation of some growth, agronomical and biochemical parameters of Vigna unguiculata (L. Walp) under salinity stress were investigated in the greenhouse and farm conditions. Plants were subjected to 0, 50, 100 and 200 mM NaCl. The increases of NaCl in the culture medium significantly (P< 0.001) decreased the growth parameters (number of leaves, noose diameter, leaf area and stem height), dry biomass (roots,...

Evaluation of seventeen cowpea genotypes across years for grain yield, yield components and yield stability in Nsukka, South-east Nigeria
Fifteen improved and two local genotypes of Vigna unguiculata were evaluated for their performance in grain yield, yield components and yield stability from 2016 to 2018. Experiments were laid out in a Randomised Complete Block Design, with three replications. Data were collected on grain yield and yield components and subjected to analysis of variance (ANOVA). Stability analysis for grain yield was conducted using...

Production and utilisation of Bambaranut (Vigna subterranea (L.) Verdc.) in Northern and Eastern Uganda
Bambaranut (BN) (Vigna subterranea (L.) Verdc.) Is a nutrient rich, drought tolerant food legume that can contribute to food security and community resilience. In Uganda however, production and utilization remain in relative obscurity. A study was conducted in Northern and Eastern Uganda to determine production and utilization practices and identify challenges and opportunities for BN improvement. Primary data on...

Evaluation of a naturally ventilated solar-venturi dryer environmental effect on the quality of dried sweet-potato slices
A naturally ventilated solar-venturi dryer (NSD) was constructed using locally available materials to improve the quality of dry sweet potato slices (SPS) for small to medium scale farmers. The study investigated the efficiency of the NSD to reduce relative humidity (RH), solar radiation and temperature effect on firmness and color of dried SPS. The maximum temperature inside NSD was 44.4°C (12:00 pm) in an empty...

Views and perspectives of local farmers on crop diversification in the North-Western Free State, South Africa
The North-Western Free State is a main contributor of South Africa’s maize production which has recently been put under enormous pressure by climate change, pests, diseases, economic factors and population growth. Crop diversification, by means of crop rotation, has potential to alleviate some of the challenges faced by the farmers and communities of the North-Western Free State. Crop rotation can improve soil...
