Challenges to ecosystem services of sustainable agriculture in West Africa
(2020)
Food security is still sub-optimal in many parts of West Africa calling for more efficient agricultural practices in mitigating food insecurity. Some of the problems faced in West African agricultural systems are bottlenecks in ruminant livestock supply, inefficiency in commercial poultry production, and loss of arthropod diversity. These issues require proper integration of farming systems, demand the closing of nutrient cycles, need diversi cation of production, and require enhancement of ecosystem services. To ...

Entwicklung einer Robotik-Lösung zur Schneckenbekämpfung in der Landwirtschaft
(2020)
Schnecken sind bedeutende Schädlinge in der Landwirtschaft. Die Ausbringung von Schneckenkorn zur Schneckenbekämpfung als Verfahren nach dem Stand der Technik hat jedoch erhebliche Nachteile. Der Erfolg ist abhängig von der vorherrschenden Witterung und damit unsicher, zudem schadet es auch Nützlingen. Eine Robotik-Lösung zu Schneckenbekämpfung arbeitet wetterunabhängig und ist in der Lage, zwischen Schädlingen und Nützlingen zu unterscheiden.
Durch einen Feldversuch konnte gezeigt werden, dass Überfahrten eines ...

Development of Energy use Profiles, Reduction Concepts, and Implementation of Renewable Energies in the Central Ugandan Pineapple Processing Chains
(2020-02)
Pineapples, like all fruits, are highly perishable and require either immediate consumption or preservation. To make them more stable and add value, four major processing methods are being employed in Uganda, i.e. drying, munaanansi (local drink), wine, and juice making. Energy is one of the main inputs required to achieve any of the processing methods. The aim of this research was to develop energy use profiles, gain insights into energy use reduction options, and to evaluate the applicability of renewable energies ...

Bacteriological quality and safety of four fluid dairy products sold in El Fayoum governorate, Egypt
(2020-11-29)
The study was designed to assess the safety and bacteriological quality of one hundred and twenty samples including (small scale fluid cream, large scale Laban rayeb, Pasteurized milk and UHT milk) (30 of each). The samples were collected randomly in their retail packages from different localities in Fayoum province, Egypt. Samples were analyzed for total bacterial count (TBC), total coliforms, fecal coliforms, Escherichia coli and Staphylococcus aureus. The mean value of TBC in small scale fluid cream and pasteurized ...

Awareness creation of smallholder farmers on and adoption of push-pull technology reduces fall armyworm (Spodoptera frugiperda) infestation on maize in Hawzien Woreda, Northern Ethiopia
(2020-11-28)
Recently, maize (Zea mays L.) production by smallholder farmers in Ethiopia has been threatened by an exotic pest called fall armyworm (FAW) (Spodoptera frugiperda J.E. Smith; Lepidoptera, Noctuidae). Devising or adopting sustainable, effective, affordable and smallholder farmers-friendly management strategies for the control of this pest are, therefore, vital. Push-Pull Technology (PPT) is considered one of the management methods for the control of FAW in East Africa. Therefore, the aim of this study is to determine ...

The potential of UAV-based remote sensing for the prediction of aboveground biomass and N fixation in legume-grass mixtures
(2020-07)
The world population is growing steadily and with it the demand for meat and animal protein. A major source of feed for livestock is grassland, which serves as high quality and protein rich forage. In addition to permanent grassland, temporary grassland is a valuable crop rotation element, especially in organic farming, since legumes in legume-grass mixtures can fix atmospheric nitrogen (NFix). To further increase the intensification in agriculture, reliable non-destructive measurement techniques are needed as an ...

Evaluation of antioxidant activity of the phenolic composition of Syrian Arbutus andrachne L.
(2020-10-18)
Arbutus andrachne L. (Grecian Strawberry tree) is widespread in the Mediterranean and the Black Sea Regions. This study aimed at determining total phenolic content and antioxidant activity of Arbutus andrachne parts (flowers, leaves, bark and fruit) collected from different parts of the Latakia Province (Syria). Our work is the first to conduct this experiment on the selected plants in Syria.
The fresh samples were extracted using ethanol 50% as an extraction solution, then the total contents of the phenolic compounds ...

Food traceability system awareness and agricultural operation: A Study of tea farms in Fujian, China
(2020-10-18)
China is establishing a Food Traceability System (FTS), but the policy implementation is behind most developed countries. The lack of FTS awareness may be a factor contributing to farming practices that are not consistent with FTS policies. Furthermore, the structure of an agri-food supply chain is a factor influencing farms’ compliance with FTS. The present study focuses on pesticide residue control and traceability issues in one of the largest tea production areas in China. It aims to examine the effect of FTS ...
