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...

Over the last decade, bamboo plantations have started to be used as vegetation filters for wastewater treatment. This treatment system can be useful in reducing wastewater discharge into the environment, thus contributing to the preservation of water resources by using the plantation's...

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...

To improve irrigation water-use efficiency, plant transpiration and soil evaporation in a maize (Zea mays L.) field in the Bulang sub-catchment of the Hailiutu River catchment in Northwest China were determined using in situ measurements. Crop transpiration (Tp) rates from Jul 15 to Oct 1, 2011...

A study was conducted to determine the effects of implementing different irrigation scheduling methods on heterogeneous container hardy ornamental nursery stocks. Four ornamental shrub species were grown in the same irrigation sector during the summer of four consecutive years (2007–2010):...

A new technique for the local adjustments in crop coefficients is presented. This is an alternative to conventional lysimeter measurements traditionally used for improved irrigation scheduling. The method is based on the combination of a two-source energy balance model and local measurements of...

Water management at different decision levels may be supported by the assessment of evapotranspiration (ET) on large spatial scales. In this study, a previously validated approach to estimating unstressed ET, based on the ability of vegetation indices to trace crop growth and thus to derive...
