Exploiting pre- and post-harvest metabolism in sweet sorghum genotypes to promote sustainable bioenergy production
(2020)Sweet sorghum's high yielding ability, low-input demands and tolerance to stresses, render it highly suitable for syrup and bioenergy production. Exploiting its biomass, however is hampered by the seasonality of its ... -
Exploring plant diversity through soil DNA in Thai national parks for influencing land reform and agriculture planning
(2021)Background. The severe deforestation, as indicated in national forest data, is a recurring problem in many areas of Northern Thailand, including Doi Suthep-Pui National Park. Agricultural expansion in these areas, is one ... -
Field scale assessment of the tsharp technique for thermal sharpening of modis satellite images using venµs and sentinel-2-derived ndvi
(2021)Remotely sensed-based surface temperature is an important tool for crop monitoring and has great potential for improving irrigation management. However, current thermal satellite platforms do not display the fine spatial ... -
FutureFarm: Addressing the needs of the European farm of the future: Findings of the first two years
(2010)In the future, European farmers will have to effectively manage information on and off their farms to improve economic viability and to reduce environmental impact. To this end, an integrated information system is needed ... -
Health effects of genetically modified food
(2009)As genetically modified (GM) foods are starting to intrude in the diet concerns have been expressed regarding GM food safety. This is a review of these concerns, and the limitations of the procedures followed in the ... -
How extraction method affects yield, fatty acids composition and bioactive properties of cardoon seed oil?
(2018)Cardoon (Cynara cardunculus L.; Asteraceae) is a perennial species with several uses, especially in the industry of energy production, while it is classified as a non-conventional energy crop within the European Union (EU). ... -
Hybrid methodology for the estimation of crop coefficients based on satellite imagery and ground-based measurements
(2019)The objective of the current study was the investigation of specific relationships between crop coefficients and vegetation indices (VI) computed at the water-limited environment of Lake Karla Watershed, Thessaly, in central ... -
Hyperspectral machine vision as a tool for water stress severity assessment in soilless tomato crop
(2018)Early detection of water deficit stress is essential for efficient crop management. In this study, hyperspectral machine vision was used as a non-contact technique for detecting changes in spectral reflectance of a soilless ... -
The identification of several dipterocarpaceae and fagaceae trees by barcode dna coupled with high-resolution melting analysis
(2021)The loss of forests is a major environmental, social, and economic problem. The disappear-ance has been occurring to an extreme degree in many parts of Southeast Asia, including Thailand. Logging and clearing of forests ... -
Identification of the key variables that can be estimated using remote sensing data and needed for Water Footprint (WF) assessment
(2014)Accurate assessment of water use is an important issue in a globally changing climate and environment, where water is becoming a scarce but essential resource. The concept "?Water Footprint (WF) of a crop is defined as the ... -
Impacts of irrigation and nitrate fertilization scenarios on groundwater resources quantity and quality of the Almyros Basin, Greece
(2021)Irrigation and nitrate fertilization scenarios were combined and simulated for crop water irrigation demands and nitrogen applications based on experiments on crop cultivation practices. Two irrigation practices (deficit ... -
Influence of an aluminized thermal screen on greenhouse microclimate and canopy energy balance
(2003)Greenhouse microclimate, energy savings, and crop transpiration were investigated during winter in a glass-covered greenhouse cultivated with a rose crop and equipped with an aluminized thermal screen. Air temperature and ... -
