TLDR
In this paper, an updated procedure for calculating reference and crop evapotranspiration from meteorological data and crop coefficients is presented, based on the FAO Penman-Monteith method.Abstract:
(First edition: 1998, this reprint: 2004). This publication presents an updated procedure for calculating reference and crop evapotranspiration from meteorological data and crop coefficients. The procedure, first presented in FAO Irrigation and Drainage Paper No. 24, Crop water requirements, in 1977, allows estimation of the amount of water used by a crop, taking into account the effect of the climate and the crop characteristics. The publication incorporates advances in research and more accurate procedures for determining crop water use as recommended by a panel of high-level experts organised by FAO in May 1990. The first part of the guidelines includes procedures for determining reference crop evapotranspiration according to the FAO Penman-Monteith method. These are followed by updated procedures for estimating the evapotranspiration of different crops for different growth stages and ecological conditions.read more

Structural Factorization of Plants to Compute Their Functional and Architectural Growth
Paul-Henry Cournède,Mengzhen Kang,Amélie Mathieu,Jean-François Barczi,Hong-Pin Yan,Bao-Gang Hu,Philippe de Reffye +6 more
TL;DR: A new mathematical model for plant growth, GreenLab, is presented, based on a powerful factorization of the plant structure, which finds applications to build trees very efficiently and to compute biomass production and distribution, in the context of functional structural models.

The water footprint of sweeteners and bio-ethanol
TL;DR: In this article, the green, blue and grey water footprint (WF) of sugar cane, sugar beet and maize in the main producing countries was assessed, based on the crop type that is used as a source and by agricultural practices and agro-climatic conditions; process water footprints are relatively small.
Water use by drip irrigated late season peaches.
TL;DR: In this paper, a 4-year experiment was conducted using a large weighing lysimeter to determine the crop coefficient and crop water use of a late-season peach cultivar (Prunus persica (L.) Batsch, cultivar O'Henry) irrigated with a surface drip system.

Natural evaporation from open water, bare soil and grass
TL;DR: It is shown that a satisfactory account can be given of open water evaporation at four widely spaced sites in America and Europe, the results for bare soil receive a reasonable check in India, and application of theresults for turf shows good agreement with estimates of evapolation from catchment areas in the British Isles.

C. H. B. Priestley,R. J. Taylor +1 more
TL;DR: In this article, the large-scale parameterization of the surface fluxes of sensible and latent heat is properly expressed in terms of energetic considerations over land while formulas of the bulk aerodynamic type are most suitahle over the sea.

The Interpretation of the Variations in Leaf Water Potential and Stomatal Conductance Found in Canopies in the Field
TL;DR: In this paper, the stomatal conductance of illuminated leaves is a function of current levels of temperature, vapour pressure deficit, leaf water potential (really turgor pressure) and ambient CO $_2$ concentration and when plotted against any one of these variables a scatter diagram results.

Yield response to water
TL;DR: In this paper, a methodology to quantify yield response to water through aggregate components which form the "handles" to assess crop yields under both adequate and limited water supply is presented, which takes into account maximum and actual crop yields as influenced by water deficits using yield response functions relating relative yield decrease and evapotranspiration deficits.
