Wheat Irrigation Management Using Multispectral Crop Coefficients: I. Crop Evapotranspiration Prediction

Transactions of the ASABE, 2007
A method widely used for irrigation management determines crop evapotranspiration (ETc) from reference evapotranspiration (ETo) calculations and estimated crop coefficients. However, standard time-based crop coefficients may fail to represent the actual crop water use, for example, when deviations in weather or agronomic constraints appreciably change ...

Climate effect on crop coefficients

2014
Crop coefficient (Kc) values are commonly used by agronomists and engineers to estimate well-watered crop evapotranspiration (ETc) as: Kc=EToKc, where ETo is a measure of evaporative demand that is estimated from weather data collected over a large grass field using the standardized reference evapotranspiration for short canopies (ETo) equation.

CROP EVAPOTRANSPIRATION AND CROP COEFFICIENTS OF VIBURNUM ODORATISSIMUM (KER.-GAWL)

Applied Engineering in Agriculture, 2005
Determination of irrigation requirements of nursery plants is becoming more important as the nursery growers are being challenged to conserve water and minimize runoff while meeting plant water needs. Historically, not enough attention has been given to the measurement of crop evapotranspiration (ETc) and crop coefficients (Kc) of ornamental plants ...

Development of crop coefficient models of castor and maize crops

European Journal of Agronomy, 2015
Abstract Castor and maize are the most commonly cultivated crops in the Rajendranagar region of Andhra Pradesh, India. The study aims to develop a crop coefficient ( K c ) models for these crops, using Lysimeter measured daily crop evapotranspiration (ET c ) data and daily reference evapotranspiration (ET 0 ) computed using FAO-56 Penman-Monteith ...

Tomato crop coefficient grown under mediterranean climate conditions. [PDF]

, 2011
The measurements of the main weather parameters for tomato crop data were collected in 2002. at experimental meteorological station "E. Pantenelli" of Bari University and CNR-Bari near Policoro (Southern Italy) to investigate the influence of weather and management on crop growth and development parameters which can contribute in difference of Kc ...
