The approach combines the basal crop coefficient (Kcb) derived from vegetation indices (VIs) with the daily soil water balance, as proposed in the FAO-56 paper, to estimate daily crop evapotranspiration (ETc) rates of orange trees. The reliability of the approach to detect water stress was also...

The performance of two operational models for calculating daily actual evapotranspiration (ET) was presented in this study. Both models used only climatic variables collected by standard weather stations. The analysis was performed during 2000, 2001 and 2006 on three irrigated varieties of...

The approaches for the estimation of evapotranspiration (ET) can be classified in “direct” methods, based on the original Penman–Monteith (PM) equation, in which the canopy resistance rc is modelled, and “indirect” methods, based on the preliminary calculation of ET for a well-watered...

Crop coefficients (the ratio of actual and reference evapotranspiration, ET/ETo) can be derived from vegetation indices (VIs) obtained by remote sensing. If ground meteorological stations are available to calculate ETo, then the FAO method for estimating the ET of actual crops may be applied in...

Italy is one of the most important maize producers in the EU, and the Po Valley plain in northern Italy is the largest maize area in the country, with over 1millionha planted. Water consumption for maize is very high because the crop covers almost 30% of the agricultural land of the plain and is...
