Dietary protein and energy requirements of Venda village chickens
(Kassel University Press, 2018-06-27)
The objective of this study was to determine the dietary protein and apparent metabolisable energy (AME) requirements of local chickens. Freshly laid eggs of scavenging chickens collected in rural villages were hatched and randomly distributed to 27 floor pens, 10 chicks per pen. Chicks were fed 9 experimental diets that were combinations of three CP levels (140, 170 and 190 g kg−1 DM) and three AME levels (11.0, 11.7 and 12 MJ kg−1) during the starter phase (0–6 weeks) and combinations of three CP levels (120, 150 ...

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 ...

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) ...

The role of trust and networks in developing Nicaraguan farmers’ agribusiness capacities
(Kassel University Press, 2018-06-11)
The main focus of most programmes in developing countries carried out by NGOs is to develop small-scale farmers’ capacities. One approach hereby is to use multi-stakeholder innovation systems, such as the ‘Nicaraguan Learning Alliance’ (NLA). However, tools for the evaluation of multi-stakeholder innovation systems are rare. This paper reports on the implementation of a conceptual framework to carry out an impact evaluation of multi-stakeholder innovation systems using the NLA as the object of study. The assessment ...
