Explaining technical inefficiency and the variation in income from apple adoption in highland Ethiopia: The role of unequal endowments and knowledge asymmetries
(Kassel University Press, 2017-02-28)
This paper considers the performance and quality of apple fruits and seedlings production in Chencha district of southern Ethiopia. The estimated, three-factor (labour, land and capital) production frontier reveals that the technical inefficiency is 60% and 48% for fruits and seedlings production, respectively. Endowments in land, apple plantation and manure are important production factors for both fruits and seedlings, while labour is significant only for seedlings production. We could not reject constant returns ...

Diversity of farming systems integrating fish pond aquaculture in the province of Kinshasa in the Democratic Republic of the Congo
(Kassel University Press, 2017-06-06)
Agriculture and aquaculture systems are used by many farmers in various tropical countries of Asia, America and Africa. They have proven their relevancy to increase the productivity of farms by optimising nutrient fluxes and reducing requirements for external fertilisers. This article analysed the current state of fish farming and the way it is integrated with other farm subsystems in the urban/peri-urban and rural areas of Kinshasa, Democratic Republic of Congo. More precisely, it examined the allocation of resources ...

Carcass and meat quality characteristics of Arsi-Bale goats supplemented with different levels of air-dried Moringa stenopetala leaf
(Kassel University Press, 2016-10-14)
This study was conducted to assess the effect of air-dried Moringa stenopetala leaf (MSL) supplementation on carcass components and meat quality in Arsi-Bale goats. A total of 24 yearling goats with initial body weight of 13.6+/-0.25 kg were randomly divided into four treatments with six goats each. All goats received a basal diet of natural grass hay ad libitum and 340 g head^(−1) d^(−1) concentrate. The treatment diets contain a control diet without supplementation (T1) and diets supplemented with MSL at a rate of ...

Participatory Rural Appraisal for Diagnostic Analysis of spate irrigation systems in Raya Valley, Ethiopia
(Kassel University Press, 2017-05-12)
Spate irrigation is a complex and unique form of water management, which represent the main source of irrigation water in semi-arid river catchments. Water is diverted from seasonal rivers by using diversion structures made by stones, earth and brushwood, located within the river bed. The modernisation of spate irrigation realised in Raya Valley (northern Ethiopia) resulted in disappointing performances. One of the main reasons for this failure was the poor consideration of the characteristics of seasonal catchments ...

Effects of drying and storage management on fungi (Aflatoxin B1) accumulation and rice quality in Cambodia
(Kassel University Press, 2017-06-06)
Rice postharvest practices of farmers incur losses that limit supply and affect global production. Aside from physical losses, quality can be affected, leading to a possible accumulation of aflatoxin B1 (AFB1) that is harmful to humans when ingested. This is particularly important for countries like Cambodia that aim for both food security and rice exports. The objective of the research was to determine the effects of different field drying and storage practices on AFB1 accumulation and milled rice quality in Cambodia. ...

Adoption of an improved bean seed variety and consumption of beans in rural Madagascar: Evidence from a randomised control trial
(Kassel University Press, 2017-10-20)
This paper studies access to, and adoption of improved seed, as well as the diffusion of improved seed information in a remote area of central Madagascar. The analysis is based on panel data gathered from 2012 to 2014 from 390 households in three villages. In 2013, a randomised control trial was applied. Half of the 390 households were randomly assigned to receive improved lima bean seed (Phaseolus lunatus), which were specifically bred for dry regions. Of the seed-receiving households, 50 % were randomly assigned ...

Beekeeping adoption: A case study of three smallholder farming communities in Baringo County, Kenya
(Kassel University Press, 2018-04-04)
In Kenya, beekeeping offers benefits which could make it attractive to smallholder farmers as a possible strategy for making their livelihoods more sustainable. However, its potential remains largely unexploited and the lack of new entrants is thought to be one key reason for a decline in beekeeping. This paper reports on a study that examined the factors affecting beekeeping adoption in Baringo County, Kenya with a focus on three smallholder farming communities. Semi-structured interviews were conducted with 90 ...

Technical efficiency and production potential of selected cereal crops in Senegal
(Kassel University Press, 2017-08-01)
This study focused on the production outcomes for five crops cultivated in Senegal: upland rice, lowland rice, groundnut, maize, and pearl millet. Technical efficiency (TE) of the production of each crop was estimated using data envelopment analysis, and the determinants of TEs were assessed using generalised linear regression analyses. Data were collected in face-to-face interviews with 66 farmers in the Kaolack region of Central Senegal during November 2011–February 2012. Average TEs for upland rice, lowland rice, ...

Roles and optimisation rate of potassium fertiliser for immature oil palm (Elaeis guineensis Jacq.) on an Ultisol soil in Indonesia
(Kassel University Press, 2018-04-04)
Potassium (K) is an essential macronutrient needed in large amounts by oil palm as it is directly involved in physiological processes. This research focused on the influence of K fertiliser on the vegetative growth of oil palm and determined the optimum rate of K fertiliser for immature plants (aged 1 to 3 years). The study was conducted at IPB-Cargill Oil Palm Teaching Farm, Jonggol, Bogor, Indonesia, from March 2013 to March 2016. The application rates were 0, 196, 392, 588, and 784 g K_2O plant^(−1) year^(−1) ...

Activities and influence of veterinary drug marketers on antimicrobial usage in livestock production in Oyo and Kaduna States, Nigeria
(Kassel University Press, 2017-09-06)
Antimicrobial usage in animals contributes to the emergence of antimicrobial resistant bacterial strains. Investigations were carried out on how the characteristics, knowledge, attitude and practices of antimicrobial marketers influenced antimicrobials usage in animal production in Oyo and Kaduna States, Nigeria. Focus group discussions, in-depth interviews and structured questionnaires were used to gather information about the characteristics and activities of antimicrobial marketers. Overall, 70 (56.9 %) of 123 ...
