Assessing automatic data processing algorithms for RGB-D cameras to predict fruit size and weight in apples
(Elsevier, 2023-10-07)
Data acquired using an RGB-D Azure Kinect DK camera were used to assess different automatic algorithms to estimate the size, and predict the weight of non-occluded and occluded apples. The programming ...
Influence of wind direction on the surface roughness of vineyards
(Springer Verlag, 2018-11-27)
Remote sensing-based models are the most viable means of collecting the high-resolution spatially distributed estimates of evaporative water loss needed to manage irrigation and ensure the effective use ...
Influence of Regulated Deficit Irrigation on Arbequina’s Crop Yield and EVOOs Quality and Sensory Profile
(MDPI, 2022-12-22)
Regulated deficit irrigation in super-high-density (SHD) olive orchards is a well-known strategy to save water and control plant vigor, without decreasing fruit or oil yield. As there is controversial ...
Determining a robust indirect measurement of leaf area index in California vineyards for validating remote sensing-based retrievals
(Springer Verlag, 2018-12-05)
Accurate ground-based measurements of leaf area index (LAI) are needed for validation of remote sensing-based retrievals used in models estimating plant water use, stress, carbon assimilation and other ...
Global transpiration data from sap flow measurements: the SAPFLUXNET database
(Copernicus Publications, 2021-06-14)
Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy, and carbon budgets at the land–atmosphere interface. However, despite being the main ...
Utility of the two-source energy balance (TSEB) model in vine and interrow flux partitioning over the growing season
(Springer Verlag, 2018-09-14)
For monitoring water use in vineyards, it becomes important to evaluate the evapotranspiration (ET) contributions from the two distinct management zones: the vines and the interrow. Often the interrow ...
Evaluation of carbon balance and carbohydrate reserves from forced (Vitis vinifera L.) cv. Tempranillo vines
(Frontiers Media, 2022-11-22)
Elevated temperatures during berry ripening have been shown to affect grape quality. The crop forcing technique (summer pruning that ‘force’ the vine to start a new cycle) has been shown to improve berry ...
Accurate estimates of land surface energy fluxes and irrigation requirements from UAV-based thermal and multispectral sensors
(Elsevier, 2023-03-28)
The two-source energy balance model estimates canopy transpiration (Tr) and soil evaporation (E) traditionally from satellite partitions of remotely sensed land surface temperature (LST) and the ...
Water stress during the post-harvest period affects new root formation but not starch concentration and content in Chardonnay grapevine (Vitis vinifera L.) perennial organs
(Elsevier, 2019-02-15)
Water stress responses during the post-harvest period were evaluated in a Chardonnay container-grown grapevines grafted onto 1103 Paulsen rootstock. The irrigation treatments were: a control treatment ...
Evaluation of transpiration in different almond production systems with two-source energy balance models from UAV thermal and multispectral imagery
(Springer, 2023-10-31)
A growing number of intensive irrigated production systems of the almond crop have been established in recent years. However, there is little information regarding the crop water requirements. Remote ...
