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

open access: yesEgyptian 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 ...

Studies on Evapotranspiration from Crops

open access: yesJournal of Agricultural Meteorology, 1987
The problems are whether evapotranspiration (ET) from paddy field would be affected by growth stage and by rice varieties, and whether the radiation method and Priestley-Taylor method for estimating ET would be applicable to paddy field.ET was measured with microlysimeter (Tomar and O'Toole, 1980A) at the eight test plots (N1-N8) in which cultivar ...

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

open access: yesThe 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.
