Interpretive Summary:

Technical Abstract: Determining accurate crop irrigation requirements is crucial towards managing water efficiently and optimizing water productivity. This presentation summarizes important considerations in deterimining crop water requirements for use in scheduling irrigation. The major topics covered include (i) the transpiration, evapotranspiration and the accumulation of biomass (ii) calculation of reference evpotranspiration (iii) calculation of crop evapotranspiration and (iv) estimation of crop evapotranspiration under water stress and limitations of the methodology.
