Comparison of different reference evapotranspiration (ET0) models and determination of crop-coefficients of french bean (Phesiolus vulgaris.) in mid hill region of Meghalaya

Journal of Agrometeorology, 2017
The water requirement and crop evapotranspiration (ETc)is determined using reference evapotranspiration (ET0) and crop-coefficient (kc). Numerous models are available for estimation of ET0,among which Penman-Monteith (FAO-56) model is considered to be ...

Reference crop evapotranspiration over Greece

Agricultural Water Management, 1991
Abstract Monthly evapotranspiration (ET) estimates for 31 locations in Greece are calculated by the Penman, Priestley-Taylor and Thornthwaite methods. The analysis of 27 years of routine meteorological data indicates that annual amounts of ET obtained by Priestley-Taylor or Thornthwaite methods do not generally agree very well with Penman ET (ETPEN ...

Reference evapotranspiration (ETo) and irrigation water requirement of different crops in Bihar

Journal of Agrometeorology, 2017
For irrigation scheduling and better management of the water, estimation of irrigation water requirement of the crop is essentially required. The study was conducted for estimation of daily reference evapotranspiration (ETo) by FAO Penman-Monteith ...

Applicability and Improvement of Different Evapotranspiration Methods of Reference Crops in Jiangxi Province [PDF]

Theoretical and Applied Climatology, 2021
Abstract To achieve accurate evaluation of evapotranspiration of reference crops (ET0) in Jiangxi, China in the absence of systematic climatological data, with reference to the FAO-56 Penman-Monteith (P-M) equation, the Pristley-Taylor (P-T) method, the Makkink method, the Hargreaves-Samani (H-S) method, the Irmak-Allen (I-A) method, the ...

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 ...

Evaluation of crop water demand for sustainable crop production using geospatial tools in a canal command of West Bengal

Journal of Agrometeorology, 2019
The agricultural sector is the primary consumer of water resources around the world, and the need for additional food production for growing population further exerts more pressure on water resources.

Estimation of Actual Evapotranspiration in Panam Canal Command Using Remote Sensing and Geographical Information System (GIS)

International Journal of Environment and Geoinformatics, 2021
Estimation of reference evapotranspiration (ET0 ) and actual evapotranspiration (ETc ) is a key factor for estimation of crop water requirement, water balance and irrigation scheduling. The FAO-56 Penman–Monteith equation has been accepted universally

Shoot water content and reference evapotranspiration for determination of crop evapotranspiration

African Crop Science Journal, 2017
Determination of water requirement for crops in resource limited areas is  challenging, yet worsened by the common assumption that all crop varieties within a species have similar water requirements. The objective of the study was to  indirectly determine crop evapotranspiration of soybean varieties, using reference evapotranspiration and shoot water ...

Regional estimation of daily to annual regional evapotranspiration with MODIS data in the Yellow River Delta wetland [PDF]

, 2009
Evapotranspiration (ET) from the wetland of the Yellow River Delta (YRD) is one of the important components in the water cycle, which represents the water consumption by the plants and evaporation from the water and the non-vegetated surfaces.
