Assessing Durum Wheat Yield through Sentinel-2 Imagery: A Machine Learning Approach
(2022)Two modeling approaches for the estimation of durum wheat yield based on Sentinel-2 data are presented for 66 fields across three growing periods. In the first approach, a previously developed multiple linear regression ... -
Crop reflectance monitoring as a tool for water stress detection in greenhouses: A review
(2016)Multisensory platforms for remote sensing measurements offer the possibility to monitor in real-time the crop health status without affecting the crop and environmental conditions. The concept of the speaking plant approach, ... -
Evaluation and cross-comparison of vegetation indices for crop monitoring from sentinel-2 and worldview-2 images
(2017)Farmers throughout the world are constantly searching for ways to maximize their returns. Remote Sensing applications are designed to provide farmers with timely crop monitoring and production information. Such information ... -
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 ... -
MONITORING CASTOR BEANS MATURITY VIA REMOTE SENSING
(2022)Castor is a crop with an evergreen habit so artificial induced ripening is an essential precondition for mechanical harvesting of new dwarf annual hybrids. Plants water content impose a determinant effect both on preharvest ... -
Potential of using satellite based vegetation indices and biophysical variables for the assessment of the water footprint of crops
(2014)Satellite remote sensing techniques play an important role in crop identification, acreage and production estimation, disease and stress detection, and soil and water resources characterization because they provide spatially ... -
The role of spatial and spectral resolution on the effectiveness of satellite-based vegetation indices
(2016)Remote Sensing applications are designed to provide farmers with timely crop monitoring and production information. Such information can be used to identify crop needs or health problems and provide solutions for a better ... -
Using laser scanner to map pruning wood in vineyards
(2013)Management zones in vineyards may be delineated by examining the spatial variability of various biophysical factors related to grapevine performance, such as vegetation indices. Among measurements of vine vigour, the ... -
Variable rate application of side-dress nitrogen on cotton in Georgia, USA
(2013)Uniform application of fertilizers is inefficient as it does not consider field variability. During the last decade, variable rate application (VRA) has become increasingly popular. The goal of this study was to asses VRA ...
