Application of check-all-that-apply (CATA) in sensory profile assessment of arabica dark roast and black pepper mixed coffee
(2021-11-29)
Black pepper coffee is one of the developing innovations in Bangka Belitung Province, Indonesia. This study aimed to assess black pepper coffee's sensory profile using the CATA (check-all-that-apply) rapid analysis method and find the formula and brewing technique most consumers liked. The study consisted of two stages: determining the sensory attributes of black pepper coffee and taking sensory data from coffee consumers with coffee and black pepper powder ratios (98:2; 96:4; and 94:6) and brewing methods (cold brew, ...

Agricultural risk assessment to enhance the food systems of the Mbororo minority community in the Northwest region of Cameroon
(2021-10-29)
Increasing population pressure, coupled with the effects of climate change manifested by longer dry seasons, wildfires, and conflicts, threatens the food systems of minority communities. In the case of the Mbororo minority community of Northwest Region of Cameroon, these threats are exacerbated by already existing problems of marginalisation. This study assesses agricultural risks in the global context of food distribution and gross domestic product that also poses a specific threat to the food system of the Mbororo ...

Variation in baobab (Adansonia digitata L.) root tuber development and leaf number among different growth conditions for five provenances in Malawi
(2020-08-21)
The baobab tree is an underutilised indigenous fruit tree in sub-Saharan Africa which, at the same time is vulnerable to overexploitation in areas close to centres of demand, as currently baobab use is limited to wild, baobab trees. Baobab seedlings are known to form root tubers, but little is known about their growth characteristics and its yield potential. This study aims to investigate the root tuber and leaf development of baobab seedlings grown from seeds of five provenances, sown at three different planting ...

Determinants of Willingness to Pay (WTP) for organic fertiliser: a case of smallholder potato farmers in KwaZulu-Natal, South Africa
(2021-12-01)
The South African smallholder sector is characterised by relatively low productivity due to persistent deterioration in soil fertility owing to declining organic matter and other essential soil nutrients. Consequently, adoption of sustainable agricultural inputs like organic fertiliser is essential. Although there is sufficient advocacy in the adoption of organic fertiliser, the economic linkage between farmers' socioeconomic factors and willingness to pay (WTP) remains under-explored. This study investigated the ...

Rainfall erosivity, soil erodibility and natural water erosion potential in the Huambo region, Angola
(2021-12-06)
The use of erosion assessment methods is critical for the sustainability of land use in tropical and subtropical regions, especially in countries lacking national information on soil erosion development, which is the case of Angola. This study aimed to evaluate the rainfall erosivity (R), soil erodibility (K), soil loss tolerance (T) and natural erosion potential (NEP) in Huambo (Angola). The R value estimated for a 25-year period was 7463 MJ·mm·ha-¹·h-¹·y-¹. K values estimated from 25 soil profiles, described in the ...

Gender differences in time-poverty among rural households in Southwest Nigeria
(2021-10-29)
This study seeks to assess gender inequality in and correlates of time poverty among 360 rural households in Southwest, Nigeria. A person is deemed to be time poor if (s)he works more than 10.5 hours per day, the internationally accepted threshold. Using the time allocation domain of the Abbreviated Women’s Empowerment in Agriculture Index, the study found that on the average, rural women and men spent about 10.3 hours and 8 hours, respectively, on work activities on a daily basis. Work activities for women were found ...

Optimising beekeeping development programs for improved productivity, income and welfare: a case study of Papua New Guinea
(2020-10-19)
Beekeeping can provide important sources of cash income for farmers in developing countries where land is unconducive to crop and livestock production systems. In many low-income countries however, attrition among beekeeping adopters remains a chronic problem, colony losses are high, support for and coordination of the sector is low, and practices, production and income from beekeeping is often inefficient. This study investigated the key drivers and practices influencing incomes from beekeeping, honey production and ...

Application of non-linear models in description of growth of dual purpose FUNAAB Alpha chickens
(2021-08-03)
Growth is explained mathematically by models that have parameters with biological interpretations. This study was conducted to compare five non-linear growth models (Gompertz, Brody, Logistics, Von Bertalanffy and Negative exponential) in order to describe growth in the three genotypes (normal feather, naked neck and frizzle feather) of the dual purpose FUNAAB Alpha chickens (n=332). Doesn’t Use Derivative iterative method of nonlinear procedure in SAS was used to estimate the model parameters. Computational difficultly, ...

Factors driving adoption and constraining the non-adoption of biofortified orange fleshed sweet potatoes (OFSP) among farmers in Abia State, Nigeria
(2020-09-22)
This study sought to determine the factors that drive the adoption and constrain the non-adoption of Orange Fleshed Sweet Potato (OFSP) varieties among farmers in Abia State, Nigeria. Multistage sampling procedure was used in selecting sixty sweet potato farmers (thirty adopters and non-adopters each). Participatory tools such as structured interview schedule, key informant interviews and personal observation were employed for quantitative and qualitative data collection. The data were analysed using descriptive ...

Determinants of households’ membership in agricultural cooperatives in Bhutan
(2021-10-05)
The Royal Government of Bhutan has been promoting agricultural cooperatives (ACs) in the country; however, the number of people joining ACs is small. This study was conducted to identify the factors influencing households' decision to join ACs in Central Bhutan. A cross-sectional survey was conducted to collect data from 384 households (192 AC members and 192 non-AC members). Trained enumerators collected data in June and July 2018 using structured questionnaires. The binary logistic regression showed that households ...
