Assessing the impact of social grant-dependency on participation of KwaZulu-Natal rural households in farming: Application of the generalised propensity score method
(Kassel University Press, 2017-11-03)
Social grants are an important instrument of social protection in South Africa, reaching millions of the poor each month. Although social grants have been found to reduce poverty and promote human development, considerable uncertainty remains about some of their incentive effects. This study uses a sample of 984 rural households selected from KwaZulu-Natal, South Africa, to investigate the potential incentive/dis-incentive effects of social grant-dependency on rural households’ participation in farming activities. ...

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 ...

Changes in biochemical characteristics and Na and K content of caper (Capparis spinosa L.) seedlings under water and salt stress
(Kassel University Press, 2017-09-04)
In order to investigate the effect of water and salt stress on caper (Capparis spinosa L.) seedlings, a randomized complete block design with five replications was carried out in 2013 at Shiraz University, Iran. Water stress had three levels: 100 % (control), 75 %, and 5 % field capacity (FC), and five levels of salinity were applied: 0 (control), 4, 8, 12, and 18 dSm^(−1). The results indicated that salinity had a significantly negative effect on chlorophyll content of caper seedlings, while drought increased this ...

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 ...

Production and milk marketing strategies of small-scale dairy farmers in the South of Rio Grande do Sul, Brazil
(Kassel University Press, 2017-12-20)
Milk production is a socio-economically relevant activity for many small-scale family farms in southern Brazil. The objective of this study was to analyse their production and marketing strategies. A questionnaire was administered to 199 farm households in Rio Grande do Sul State to collect information on farm assets and activities, and particularly on the contribution of milk sale to farm income. Through categorical principal component analysis and two-step clustering, farmers were classified into three types: farmers ...

The role of State Forest Enterprises in the payments for Forest Environmental Services Programme in Vietnam
(Kassel University Press, 2017-12-17)
To promote pro-poor payments for environmental services, it is necessary to identify institutional options that reduce transaction costs and organisational problems associated with establishing and maintaining contracts with small-scale environmental service providers. This study examined the dual functionality of state forest enterprises (SFEs) in the implementation of the Payments for Forest Environmental Services (PFES) Program in Vietnam. We considered whether SFEs’ involvement in the programme could reduce ...

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 ...

Bionomics of the sweet potato weevil, Cylas puncticollis (Coleoptera: Brentidae) on four different sweet potato varieties in sub-Saharan Africa
(Kassel University Press, 2018-05-07)
Sweet potato (Ipomoea batatas (L.) Lam.) is an important staple food crop in sub-Saharan Africa. A limiting production factor is infestation by the sweet potato weevil Cylas puncticollis (Boheman) (Coleoptera: Brentidae). The use of host plant resistance is an essential component of Integrated Pest Management (IPM). Therefore, the bionomic parameters of C. puncticollis were studied under laboratory conditions (30 ± 1 °C and 75 ± 5 % RH) on four sweet potato varieties commonly grown in Ghana (Apumoden, Ligri, Bohye, ...
