The impact of irrigation distribution uniformity and mulching soil on vegetative growth and yield of sweet fennel and squash plants
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-03-31)
Water shortage under climate change impacts performed the driving forces to enhance the agricultural practices to maximize the food production. Improve the distribution of irrigation water with mulching soil to satisfy the plants needs and provide optimum conditions for production consider the main objective of the current study. Two experiments of the study were conducted out at Central Laboratory for Agriculture Climate (CLAC), Agriculture Research Center, Egypt during winter and spring seasons of 2016/2017 and ...

Was steht dem Wissenstransfer zur Tiergesundheit in der landwirtschaftlichen Nutztierhaltung entgegen?
(2021-09)
Produktionskrankheiten sind (auch in der ökologischen) Nutztierhaltung weit verbreitet und werden in der Gesellschaft zunehmend als negativer externer Effekt wahrgenommen. Sie führen zum Einsatz von Antibiotika, sind Ausdruck eines beeinträchtigten Tierwohls und verursachen den landwirtschaftlichen Betrieben Ausfallkosten. Obwohl zu den Ursachen und der Vorbeugung viel geforscht wurde sind Produktionskrankheiten weit verbreitet. Ziel der vorliegenden Arbeit war es, den mit dem Begriff Wissenstransfer beschriebenen ...

Fine-scale grassland monitoring using unmanned aerial vehicle borne remote sensing
(2020-04)
RS is widely employed as a non-destructive methodology to monitor grasslands. Usage of UAV as the RS platform benefits to provide high spatial (fine-grain) and temporal resolution, unclouded data over small grassland extent. Therefore, this thesis evaluated the applications of UAV-borne RS for fine-scale grassland monitoring along with practical farm condition. Grass biomass estimation, predicting forage quality of grass and mapping invasive lupine in grasslands are considered as applications of UAVborne RS.

Investigation of drying behavior and color development of beef slices for development of non-invasive monitoring approaches
(2021)
Meat drying has a long tradition worldwide and technically dried meat is increasingly valued as a low-fat snack or high-protein food product. Convection drying is widely used in industrial food preservation and has to provide high process efficiency and high product qualities, which can be contradictory. Therefore, it is important to understand the changes that occur in the product in order to develop drying strategies that consider process and product efficiency each at an acceptable level. The objective of this ...

Income Diversification trough Animal Husbandry for Smallholder Vanilla Farmers in Madagascar
(2020-05-07)
The SAVA region in northeastern Madagascar is the largest vanilla producing area globally. Here, we investigated the role of animal husbandry (AH) for income diversification of small-scale vanilla farmers. To do this, 300 household heads were interviewed about livestock ownership, management and marketing. This information was complemented by data from 1800 households (HHs) on involvement in vanilla production (VP) and AH. Throughout the region, 83 % of HHs produced vanilla and 84 % kept livestock. Chicken-keeping ...

Does the non-farm sector affect production efficiency of the Vietnamese agricultural sector? A stochastic frontier production approach
(2020-12-24)
This study examines the impact of the non-farm sector on farm value-added and production efficiency in the Vietnamese agricultural sector by using data from the Vietnam Household Living Standard Survey 2012. Production function and stochastic frontier production analysis is used to determine the impact, and the instrumental variables method is applied to address endogeneity. We find that the Vietnamese non-farm sector has a positive effect on both farm value-added and efficiency. This result indicates that income ...

Competitiveness of sea buckthorn farming in Mongolia: A policy analysis matrix
(2020-05-09)
Sea buckthorn (Hippophae rhamnoides L.) provides multiple products that are beneficial to human health. In addition, the plant is also used to combat desertification. In contrast to the vast ecological, agronomic and nutritional literature on this species, little is known about its economic and marketing aspects, particularly in Central Asia. We therefore analysed the private and social competitiveness of sea buckthorn farming in 21 households of Bulgan county of Khovd province in Mongolia. The results show that half ...

Spatial variation of nutritional content in Enhalus acoroides (L.f.) royle seeds and seed pods
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-04-14)
Coastal and small islands communities generally have limited access to fresh vegetables. The tropical seagrass Enhalus acoroides tends to fruit during the rainy season, when sea conditions often prevent fishing. Coastal communities in several countries, including Indonesia, traditionally collect seagrass fruits for food and traditional remedies. This study measured levels of 6 key nutrients in Enhalus acoroides fruit (seeds and seedpods). Samples were collected from two sites where E. acoroides fruits are harvested ...

The diversity and contribution of indigenous edible fruit plants to the rural community in the Gayo Highlands, Indonesia
(2020-05-15)
The Gayo Highlands offer different indigenous edible fruit species (IEFs) used by the rural community, essentially to provide products such as fruits, oil, medicine, nuts, and fodder. In recent times, these IEFs are being threatened by over-exploitation and biodiversity loss. This study, therefore, aimed to explore the diversity of IEFs and evaluate its contribution to the enhancement of the rural community income in the Gayo Highlands region. The plant materials were randomly collected from nine villages in three ...

Influence of stage of ripening and dietary concentration of Noni (Morinda citrifolia L.) powder on broiler performance
(2020-04-08)
Phyto-additives in poultry diets enhance growth, feed eciency and product quality and minimise the possible risk of residues from chemical additives. There are reports on the use of noni (Morinda citrifolia) fruit powder as phytoadditive in poultry diets but information on the eect of fruit ripening is scanty. Hence, this study compared the eect of unripe and ripe noni fruit owder on broiler performance. A control diet without and 4 diets containing two levels (0.25 and 0.5 %) unripe and ripe fruit powder were fed ...
