Clay pot irrigation for tomato (Lycopersicon esculentum Mill) production in the north east semiarid region of Ethiopia
(Kassel University Press, 2011)
Water shortage is one of the major constraints for production of horticultural crops in arid and semiarid regions. A field experiment was conducted to determine irrigation water and fertilizer use efficiency, growth and yield of tomato under clay pot irrigation at the experimental site of Sekota Dryland Agricultural Research Center, Lalibela, Ethiopia in 2009/10. The experiment comprised of five treatments including furrow irrigated control and clay pot irrigation with different plant population and fertilization ...

Varying the dietary supply of C and N to manipulate the manure composition of water buffalo heifers in Oman
(Kassel University Press, 2012)
Optimizing the composition of manure has the potential to reduce nutrient losses to the environment and to increase crop yields. In this study the effect of dietary ratios of carbon (C) to nitrogen (N) and neutral detergent fibre (NDF) to soluble carbohydrates (SC) on faeces composition of water buffalo heifers was assessed. Two digestibility trials were conducted with 12 animals each, fed one control and four test diets composed to achieve (1) high C/N and high NDF/SC ratios (HH), (2) low C/N and low NDF/SC ratios ...

Strategies for coping with feed scarcity among urban and peri-urban livestock farmers in Kampala, Uganda
(Kassel University Press, 2012)
Livestock keeping is increasingly becoming more popular in Kampala, the capital city of Uganda. However, lack of feed is a real challenge. Inadequate feed supply in urban areas is due to many interacting factors, which include among others land shortage, high cost of feeds, climate risks and poor quality of feeds. The objective of this study was to identify and examine the effectiveness of the strategies adopted by livestock farmers in urban and peri-urban areas of Kampala, Uganda to cope with feed scarcity. A total ...

Swamp buffalo keeping – an out-dated farming activity? A case study in smallholder farming systems in Xishuangbanna, Yunnan Province, PR China
(Kassel University Press, 2012)
Expansion of rubber tree plantations and agricultural mechanization caused a decline of swamp buffalo numbers in the Naban River National Nature Reserve (NRNNR), Yunnan Province, China. We analysed current use of buffaloes for field work and the recent development of the regional buffalo population, based on interviews with 184 farmers in 2007/2008 and discussions with 62 buffalo keepers in 2009. Three types of NRNNR farms were distinguished, differing mainly in altitude, area under rubber, and involvement in livestock ...

Pesticide-handling practices of smallholder coffee farmers in Eastern Jamaica
(Kassel University Press, 2013)
Pesticide use among smallholder coffee producers in Jamaica has been associated with significant occupational health effects. Research on pesticide handling practices, however, has been scarce, especially in eastern Jamaica. This explorative study aims at filling this gap and provides a first basis to develop effective interventions to promote a safer pesticide use. A random sample of 81 coffee farmers was surveyed. The majority of farmers reported to suffer from at least one health symptom associated with pesticide ...

Characteristics, socioeconomic benefits and household livelihoods of beef buffalo and beef cattle farming in Northeast Thailand
(Kassel University Press, 2012)
Since the Thai economy experiences rapid growth, agricultural systems, i.e. crop-livestock systems, are changing rapidly. On account of these changes, buffalo and cattle production has to be re-examined in terms of performance characteristics and roles of livestock for farm households in order to initiate suitable development programmes. Therefore, this study aimed to investigate the present characteristics of beef buffalo and beef cattle farms in Northeast Thailand. Using a semi-structured questionnaire, 121 randomly ...

Successful rescue and field establishment of native banana varieties severely affected by rhizome rot
(Kassel University Press, 2012)
Rhizome rot disease caused by Erwinia spp. is emerging as a major problem in banana nurseries and young plantations worldwide. Management of the disease is possible only in the initial stages of development. Currently no method is available for rescuing plant material already infected with this pathogen. A total of 95 Nanjanagud Rasabale and 212 Elakki Bale suckers were collected from different growing regions of Karnataka, India. During nursery maintenance of these lines, severe Erwinia infection was noticed. We ...

Management practices and challenges in smallholder indigenous chicken production in Western Kenya
(Kassel University Press, 2013)
The potential benefit of indigenous chicken (Gallus domesticus) production is still under-exploited in Kenya despite the efforts by different stakeholders to mainstream this production system as a pathway to rural development. The production system is often characterized by low input-low output productivity and low commercialization of the enterprise. This study which dwells on the current management practices and challenges faced by smallholder indigenous chicken farmers was conducted to gain insights into the ...

Climate change and hunger as the challenges in the global food system
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2013-04-25)
In the last decades, there has been a growing tendency towards international trade and globalisation, particularly leading to a significant increase in flows of agricultural commodities worldwide. From a macroeconomic perspective, the commodity projections are more optimistic than the previous years and the long run tendency shows an increasing demand for feedstock. However, the strong shifts of shocks and fluctuations (in terms of prices and volumes) are a concern to global food security, with the number of hungry ...

Documenting the social and environmental consequences of oil palm plantations in Nicaragua
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2017-12-29)
Palm oil production is expanding in many tropical areas worldwide. The implications for the landscape, social relations and living conditions in the respective areas are the subject of a controversial debate. This article explores the social, economic, and environmental impacts caused by palm oil production in two places in south-eastern Nicaragua: Kukra Hill and Boca de Sábalos. From a theoretical perspective of political ecology, this article reflects on the opportunities and limitations of non-governmental ...
