Objectives

The students should acquire the knowledge to quantify the water use by the crop known the climatic conditions and the management

Contents

Climate effect on water use by a crop: the reference evapotranspiration (ET0) according to the FAO Penmann-Monteith method (16 h)

Crop evapotranspiration without water limitation according to the method of dual coefficients reported in the Paper No 56 by FAO to estimate evaporation and transpiration (8 h).

Crop evapotranspiration of a crop in water limited conditions. Soil water balance and water stress coefficients (8h).

Irrigation water quality assessments. Plant salt tolerance. Leaching and root zone salinity control (8h).

Water productivity. Relationship between water applied with irrigation and crop yield. Water foot print calculation (8h).

Teaching Methods

The course includes lectures and exercises. During the exercises the student will learn how to calculate the crop water consumption on a spreadsheet, and will be introduced to the AquaCrop model. During the field exercises, the student will learn how to measure: the leaf area, the fraction of radiation intercepted by a culture, stomatic conductance, the spectrum of radiation reflection, and the temperature of the leaf cover.
