Evapotranspiration and Crop Coefficient of Sorghum ( L.) at Melkassa Farmland, Semi-Arid Area of Ethiopia

Air, Soil and Water Research, 2023
Sorghum has an enormous role in the economy of sorghum-growing nations. Supplying a precise amount of water to a crop based on crop needs is the main agenda in implementing water-saving agriculture.

Crop coefficient determination and evapotranspiration estimation of watermelon under water deficit in a cold and arid environment. [PDF]

Front Plant Sci, 2023
To investigate the evapotranspiration and crop coefficient of oasis watermelon under water deficit (WD), mild (60%–70% field capacity, FC)and moderate (50%–60% FC) WD levels were set up at the various growth stages of watermelon, including seedling stage

Development of Smart Weighing Lysimeter for Measuring Evapotranspiration and Developing Crop Coefficient for Greenhouse Chrysanthemum. [PDF]

Sensors (Basel), 2022
The management of water resources is a priority problem in agriculture, especially in areas with a limited water supply. The determination of crop water requirements and crop coefficient (Kc) of agricultural crops helps to create an appropriate ...

A remote sensing approach to estimate variable crop coefficient and evapotranspiration for improved water productivity in the Ethiopian highlands

Applied Water Science, 2023
Proper and reasonable estimation of actual evapotranspiration is critical for the design, operation, and management of irrigation systems. However, the density of climatic stations is low in many parts of Ethiopia to estimate spatially reasonable ...

Comparing Methods to Extract Crop Height and Estimate Crop Coefficient from UAV Imagery Using Structure from Motion

Remote Sensing, 2022
Although it is common to consider crop height in agricultural management, variation in plant height within the field is seldom addressed because it is challenging to assess from discrete field measurements.

Estimation of Actual Evapotranspiration and Crop Coefficient of Transplanted Puddled Rice Using a Modified Non-Weighing Paddy Lysimeter

Agronomy, 2022
Lysimetric and eddy covariance techniques are commonly used to directly estimate actual crop evapotranspiration (ETa). However, these technologies are costly, laborious, and require skills which make in situ ET estimation difficult, particularly in ...
