A modified STIC model for estimating crop evapotranspiration

, 2021
A novel application of the STIC model (Mallick et al. 2014, 2015a) was developed by the author to estimate crop evapotranspiration, E, at a field or sub-field scale without recourse to any remote sensing (RS), i.e.

Determination of water requirement and crop coefficient for strawberry using lysimeter experiment in a semi-arid climate

H2Open Journal, 2022
This research is aimed at measuring the water requirement, crop coefficient, and strawberry canopy coverage for efficient water consumption management. Two volumetric lysimeters were installed during the growing season of 2018 and 2019 at an agricultural

Temporal Downscaling of Crop Coefficient and Crop Water Requirement from Growing Stage to Substage Scales

The Scientific World Journal, 2012
Crop water requirement is essential for agricultural water management, which is usually available for crop growing stages. However, crop water requirement values of monthly or weekly scales are more useful for water management.

Estimation of Evapotranspiration ETc and Crop Coefficient Kc of Wheat, in south Nile Delta of Egypt Using integrated FAO-56 approach and remote sensing data

Egyptian Journal of Remote Sensing and Space Sciences, 2012
Crop water requirements are represented by the actual crop evapotranspiration. Estimation of crop evapotranspiration (ETc) and crop coefficient using remote-sensing data is essential for planning the irrigation water use in arid and semiarid regions ...

Reference crop evapotranspiration derived from geo-stationary satellite imagery: a case study for the Fogera flood plain, NW-Ethiopia and the Jordan Valley, Jordan

, 2010
First results are shown of a project aiming to estimate daily values of reference crop evapotranspiration ET0 from geo-stationary satellite imagery. In particular, for Woreta, a site in the Ethiopian highland at an elevation of about 1800 m, we tested a ...

Water requirement and crop coefficients of sorghum in Apodi Plateau

Revista Brasileira de Engenharia Agrícola e Ambiental, 2021
Sorghum is of significant economic importance for Northeastern Brazil, since it exhibits high growth rates in regions with irregular rainfall distribution and high temperatures, and is an alternative to corn, which has greater water requirements. Despite

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

Environmental 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 ...

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

Sensors, 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 ...
