Nutrient utilisation and blood chemistry of Red Sokoto bucks fed on diets with different inclusion levels of raw and soaked roselle (Hibiscus sabdariffa L.) seeds
(Kassel University Press, 2018-04-11)
This study evaluated nutrient utilisation and blood chemistry of Red Sokoto bucks fed a 10 and 20 % inclusion level of raw, water- and lime-soaked Hibiscus sabdariffa L. seeds in rice bran based diets. 21 Red Sokoto bucks aged 8–10 months and weighing 9–13 kg were randomly allotted into six treatments with three bucks each, while a seventh dietary treatment with zero inclusion of seeds served as control in a 2 × 3 factorial arrangement using a complete randomised design. The results indicated that increase in dietary ...

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 ...

The Suppressive Nature of Compost against Pythium spp: evaluation of compost-based applications in two host pathogen systems using bioassays and molecular fingerprinting
(2018-08-14)
The suppressive effect of composts on soil-borne plant pathogens has been widely reported in the scientific literature. However, the role of the compost microbiome, in this respect, is still not well understood. The general goal of this research was the molecular-biological characterisation of the microbiomes of two compost types within the host-pathogen system Pythium ultimum and cucumber, thereby contributing to understanding the role of the microbial structure of the chosen composts in this specific system. An ...

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 ...

The ‘forma specialis’ issue in Fusarium: A case study in Fusarium solani f. sp. pisi
(2018-01-19)
The Fusarium solani species complex (FSSC) has been studied intensively but its association with legumes, particularly under European agro-climatic conditions, is still poorly understood. In the present study, we investigated phylogenetic relationships and aggressiveness of 79 isolates of the FSSC collected from pea, subterranean clover, white clover and winter vetch grown under diverse agro-climatic and soil conditions within Temperate and Mediterranean Europe. The isolates were characterized by sequencing tef1 and ...

Roots of symptom-free leguminous cover crop and living mulch species harbor diverse Fusarium communities that show highly variable aggressiveness on pea (Pisum sativum)
(2018-02-14)
Leguminous cover crop and living mulch species show not only great potential for providing multiple beneficial services to agro-ecosystems, but may also present pathological risks for other crops in rotations through shared pathogens, especially those of the genus Fusarium. Disease severity on roots of subterranean clover, white clover, winter and summer vetch grown as cover crop and living mulch species across five European sites as well as the frequency, distribution and aggressiveness to pea of Fusarium spp. ...

Post-harvest handling practices and associated food losses in sweetpotato and cassava value chains of southern Ethiopia
(2018-02-12)
In dieser Studie wurden die Nachernte-Ketten von Süßkartoffel und Maniok in Südäthiopien untersucht. Schlüsselfaktoren, die für Nahrungsmittelverluste verantwortlich sind, wurden identifiziert und mögliche Verbesserungsmaßnahmen vorgeschlagen.
Es wurden innerhalb der Süßkartoffel-Wertschöpfungskette die landwirtschaftlichen Betriebe und der Einzelhandel mit einem Ausschuss von bis zu 20% bzw. 25% als "hot-spots"
