First report and population dynamics of the Tobacco Thrips, Thrips parvispinus (Karny) (Thysanoptera: Thripidae) on ridged gourd, Luffa acutangula (L.) Roxy in selected export fields in southern Ghana
(2022-12-07)
Thrips attack several crops causing considerable economic damage. To prevent this damage, sticky traps can be used to monitor their population for the timely execution of management interventions. Ridged gourd or turia (Luffa acutangula (L.) Roxy) is an important Asian vegetable exported regularly to the European Union market from Ghana. However, this vegetable has been intercepted severally at the point of entry because of thrips infestation. The current study is aimed at identifying and monitoring thrips population ...

Morphological characterisation of three indigenous Mozambican cattle populations
(2022-12-06)
Information on phenotypic and morphometric variation is important in the characterisation of indigenous cattle breeds. The objective of this study was to assess the morphological variation of the indigenous Angone, Landim, and Tete cattle populations of Mozambique, kept under traditional management systems. These cattle are farmed mainly for meat and draught power, although they can produce some milk, especially the Landim. Data were collected through a survey of twenty-three villages in Maputo, Gaza, Inhambane ...

Prevalence of bovine mastitis and antimicrobial sensitivities of the bacterial causes in smallholder farms of Kisumu County, Kenya
(2022-12-20)
Prevalence of bovine mastitis in Kisumu County, risk factors and antibiotic sensitivities of the causative bacteria were determined in this cross-sectional study. Sub-clinical mastitis (SCM) was diagnosed using California Mastitis Test (CMT). Risk factors were identified through the administration of 64 questionnaires and assessment of 134 lactating cows. Bacteria were identified by culturing 72 CMT-positive udder quarter milk samples and their sensitivities to antibiotics investigated using Kirby-Bauer disc diffusion ...

Rural alternatives for local development: an intercultural analysis (cases from northern Ecuador)
(2022-12-31)
This study takes a historical and analytical tour of the experiences, ways of life and community knowledge oriented towards the construction of alternatives to achieve development in the communities of Cotacachi and Yunguilla, Ecuador. Rural development has been an extremely neglected issue by the Ecuadorian government and local authorities. In the 21st century, this neglect continues to impact peasants and indigenous people, manifesting itself in all kinds of inequalities that a ect the quality of life of their ...

The ‘fine balance’ of West African savannah parklands: biomass generation versus firewood consumption
(2022-03-15)
In sub-Saharan Africa, the long-awaited fuelwood gap, resulting of the unbalance between a declining supply of firewood and the increasing demand of households, remains a latent social-ecological challenge. As its quantitative basis remains elusive, we have assessed agroforestry parklands, assumedly main providers of firewood, and firewood consumption in Dassari, Benin and Dano, Burkina Faso, both in the West African savannah. Data collected included botanical inventories, tree biomass estimations, householders’ ...

Effects of Petiveria alliacea (guinea hen weed) leaf extract on fermentation parameters, nutrient digestibility and faecal worm egg count in growing West African dwarf goats
(2022-03-21)
Medicinal plants are used in animal feeding as natural antimicrobial to improve nutrient utilisation and health status of animals. This study assessed the effects of varying concentration of Petiveria alliacea leaf extract (PLE) on fermentation parameters, nutrient digestibility, nitrogen utilisation and faecal worm egg count of growing West African dwarf goats. Twenty- four (24) growing West African dwarf bucks with average body weight of 8.50 ± 0.55 kg were divided into four treatment groups with six bucks each ...

Influencing factors of performance of agricultural cooperatives in the Vietnamese Mekong Delta
(2022-03-22)
The study identifies the influencing factors of the performance of agricultural cooperatives (ACs) in the Mekong Delta (MD) of Vietnam. The study used a disproportionate stratified sampling method, with 308 valid samples collected from the Department of Agriculture and Rural Development in the districts and the Management Boards of ACs in 9 provinces in MD. Performance of AC is measured against five indicators, namely return on sales (ROS), return on assets (ROA), return on equity (ROE), responsiveness to cooperative ...

Determinants of sustainable agricultural intensification adoption and impacts on household productivity and consumption in Rwanda
(2022-01-31)
Sustainable agricultural intensification (SAI) involves those farming systems that produce in ways that improve or maintain productivity with minimal e ects on the environment so that critical farm resources can endure. The objective of this paper is to investigate the determinants and impacts of the adoption of three interdependent sustainable agricultural intensification practices (crop residue retention, minimum tillage, and maize-legume diversification) and their combinations on household productivity and consumption ...

Comparison of linear discriminant analysis, support vector machine and artificial neural network in classifying Nigerian local turkeys based on plumage colours using biometric traits
(2022-10-18)
The ability of linear discriminant analysis (LDA), support vector machine (SVM), and artificial neural network (ANN) models to differentiate biometric traits of Nigerian local turkeys was investigated in this study. The biometric traits (bodyweight, body length, breast girth, thigh length, shank length, keel length, wing length, and wingspan) in 200 (20-week-old) turkeys were measured. Seventy percent of the datasets were used to train the three models, with the remaining 30% being used to test their performance. All ...

Use of corncob biochar and urea for pakchoi (Brassica rapa L.) cultivation: Short-term impact of pyrolysis temperature and fertiliser dose on plant growth and yield
(2022-10-18)
This study aimed to evaluate the effect of pyrolysis temperature of corncob biochar as a soil amendment and urea fertiliser on the growth and yield of pakchoi. Pakchoi was cultivated in pots
(13 cm height, 19 cm upper diameter, and 13.5 cm bottom diameter). Two factors including pyrolysis temperature of biochar and urea dose were combined with four levels each. Pyrolysis temperature factor consisted of B0 (no biochar), B1 (250 °C), B2 (300 °C), and B3 (350 °C). Urea dose consisted of F0 (no urea), F1 (0.6 g pot-¹), ...
