Reference Crop Evapotranspiration Estimation Using Remote Sensing Technique

2020
Reference crop evapotranspiration (ETo) is a basic parameter for irrigation water management, and its estimation is crucial, and therefore, there exists a number of empirical and physically based approaches for its estimation. However, lack of conventional ground weather station data, required by these approaches, is a big challenge in a developing ...

Reference crop evapo-transpiration (ET0) over Bangladesh and its implication in crop planning

2005
An accurate estimate of crop water requirement is of vital importance in planning, design and operation of irrigation and water resources system. Relationships between the evapo-transpiration of a preselected crop (the reference crop), which is referred to as reference evapo-transpiration (ET0), and other crops are established by multiplying ET0 by ...

Wavelet network model for reference crop evapotranspiration forecasting

2007 International Conference on Wavelet Analysis and Pattern Recognition, 2007
Reference Crop Evapotranspiration(RCE) plays an important role in the agricultural production management. RCE characterized by its nonlinearity and multi-time scale feature, may vary with the change of time under the influence of stochastic variation of meteorological factors such as temperature, sunlight, wind speed and so on.

Crop Insurance and Statutory Reference Prices

Federal crop insurance is a farm payment program since farmers pay on average only about 38% of the total actuarially-fair premium. Not considering the resulting net insurance indemnity payments to farmers when setting statutory reference prices means reference prices could exceed the total economic cost of production.

Neural computing modeling of the reference crop evapotranspiration

Environmental Modelling & Software, 2012
Reference crop evapotranspiration (ET"o) estimation is of importance in irrigation water management for the calculation of crop water requirements and its scheduling, in rainfall-runoff modeling and in numerous other water resources studies. Due to its importance, several direct and indirect methods have been employed to determine the reference crop ...
