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 ...

Farmers’ Supply Response and Perception of Rice Procurement Program in Bangladesh
(2020-10-18)
Rice farmers in Bangladesh do not get proper returns due to lower market prices and many unexpected situations that may affect the supply of rice production. To protect the farmers, the government introduced the rice procurement program. This study tried to analyse the supply response to rice production and assess the farmers’ perception of government procurement program including their financial risk of rice production. Vector autoregressive (VAR) model was employed to analyse the supply response of rice using ...

Does backyard-keeping of native sows by smallholders in Quezon, Philippines, offer sustainability benefits compared to more intensive management of exotic sow breeds?
(2020-04-03)
The present study in Quezon, Philippines, assessed the sustainability of small-scale production systems, based either on native or on exotic sow breeds, using different survey tools in a socio-economic approach. In two research periods, data sets with 49 households and 68 households, respectively, all smallholder farmers keeping ≤5 sows, were compiled. In 2016, four municipalities were purposively selected, each representing one of Quezon’s four districts. In 2017, two municipalities, both with larger populations of ...

Are farmer perceptions among significant determinants of adoption of agricultural diversity in Malawi? A case of Lilongwe district
(2020-12-14)
Agricultural diversity can strengthen resilience of livelihood of farmers to climate change and market uncertainties while, potentially at the same time, o ering better dietary and nutritional prospects for households. Adoption of agricultural diversity in Malawi is low. Policy-makers, researchers, non-governmental organisations (NGOs), and extension staff need to understand dynamics of adoption of agricultural diversity in order to develop appropriate policies and interventions to promote agricultural diversification. ...

Effect of Village Savings and Loan Associations on adoption of index-based crop insurance under limited liabilities
(2020-03-26)
A household survey and focus group discussions were conducted to quantify the general determinants of an index-based crop insurance adoption under limited liabilities in Burundi, and specifically the effect of existing Village Savings and Loan Associations (VSLAs). The survey sample comprised of 40 crop insurance adopters, 40 non-adopters and 40 drop-outs in Bukirasazi and Makebuko communes of Gitega province.
The results indicated that saving money (by VSLAs) for upcoming premium payments and regularly VSLA meetings ...

Development of a new methodology in sensory science to detect the intention-behaviour gap in organic food consumption and investigate the effect of this gap on consumer’s subjective wellbeing
(2020-08)
Aktuelle Umweltherausforderungen wie die globale Erwärmung, der Klimawandel und der Verlust der biologischen Vielfalt und der natürlichen Ressourcen hängen mit dem Verhalten der Menschen zusammen. Nicht nachhaltige Produktion und Konsum erklären die meisten dieser Herausforderungen. Daher interessieren sich immer mehr Verbraucher für Bio-Lebensmittel, um ihr Engagement für ein nachhaltigeres Lebensmittelverhalten zu demonstrieren. Infolgedessen ist der Markt für Bio-Lebensmittel in letzter Zeit gewachsen. Verbraucher ...

Occurrence, distribution and alternative hosts of Wheat streak mosaic virus infecting ginger in Kaduna State, Nigeria
(2020-06-29)
A field survey was conducted during the 2018 rainy season (June – October) in three major ginger producing Local Government Areas (LGAs) of Kaduna State, Nigeria to determine the occurrence and spread of wheat streak mosaic virus (WSMV) infecting ginger. Symptomatic and asymptomatic ginger leaf samples (n=180) and weed samples (n=45) were collected from the surveyed fields and indexed against WSMV using Double Antibody Sandwich Enzyme-linked Immunosorbent Assay (DAS-ELISA). The results obtained showed that WSMV ...

Typology of smallholder’s pig production systems in South Kivu, Democratic Republic of Congo: Challenges and opportunities
(2020-06-30)
Pig farming plays an important role in farmers’ livelihoods in many tropical countries. It contributes to food security of the poorest as well as the development of rural economy through multiplier effects. In the South Kivu province, pig farms are almost exclusively owned by smallholders. A few studies have attempted to describe thoroughly pig farming systems in this province. This study was undertaken to characterise pig production systems, in order to better understand their current situation, namely constraints ...
