Assessing Crop Coefficients for Natural Vegetated Areas Using Satellite Data and Eddy Covariance Stations

open access: yesSensors, 2017
The Food and Agricultural Organization (FAO) method for potential evapotranspiration assessment is based on the crop coefficient, which allows one to relate the reference evapotranspiration of well irrigated grass to the potential evapotranspiration of ...

Modifying the Dual Crop Coefficients with Leaf Area Index and Meteorological Factors to Improve the Estimated Evapotranspiration from Maize Fields

open access: yesGuan'gai paishui xuebao, 2023
【Objective】 Evapotranspiration consists of plant transpiration (Tr) and soil surface evaporation (Es); It is a critical component in the hydrological cycle, often estimated using meteorological and plant data.

Climate variability impact on crop evapotranspiration in the upper East region of Ghana

open access: yesEnvironmental Challenges
Ghana's agriculture is primarily rain-fed, making it vulnerable to the impact of climate variability and climate change. This study examined the trends and impact of climatic variability and evapotranspiration on the crop evapotranspiration of selected ...

Measuring Crop Evapotranspiration Over Hilly Areas

open access: yes, 2018
Agricultural production systems around the Mediterranean basin rely mostly on rainfed agriculture in hilly watersheds, although some irrigation is sustained downstream of water reservoirs. With climate change and increasing demand for water, most commonly cultivated species, particularly cereals, are exposed to high risks of water shortages during the ...

Tomato and cowpea crop evapotranspiration in an unheated greenhouse

open access: yesWater Science and Engineering, 2008
With the development of protected cultivation of vegetables in China, it is necessary to study the water requirements of crops in greenhouses. Lysimeter experiments were carried out to investigate tomato (2001) and cowpea (2004) crop evapotranspiration ...
