TLDR
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.Abstract:
This publication presents 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. The method presented in part A takes into account maximum and actual crop yields as influenced by water deficits using yield response functions relating relative yield decrease and evapotranspiration deficits. Part B gives an account of water-related crop yield and quality information for 26 cropsread more

Crop evapotranspiration : guidelines for computing crop water requirements
TL;DR: 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.

The green, blue and grey water footprint of crops and derived crop products
TL;DR: In this article, the authors used a grid-based dynamic water balance model to estimate the green, blue and grey water footprint of global crop production in a spatially-explicit way for the period 1996-2005.

Deficit irrigation for reducing agricultural water use
TL;DR: Several cases on the successful use of regulated deficit irrigation (RDI) in fruit trees and vines are reviewed, showing that RDI not only increases water productivity, but also farmers' profits.

AquaCrop-The FAO Crop Model to Simulate Yield Response to Water: I. Concepts and Underlying Principles
TL;DR: The FAO crop model AquaCrop as mentioned in this paper is a water-driven growth engine, in which transpiration is calculated first and translated into biomass using a conservative, crop-specific parameter: the biomass water productivity, normalized for atmospheric evaporative demand and air CO 2 concentration.

Advances in Soil Science
TL;DR: The topics addressed in this volume of a continuing series on the soil sciences are soil-water repellency, nutrient transformations in soils amended by green manures, and the physical fractionation of soil and organic matter in primary particle size and density separates as discussed by the authors.

Photosynthesis of leaf canopies
TL;DR: The development of a procedure to calculate the effect of certain environmental factors on the rate of photo-synthesis imposed mainly geometrical problems, which were solved in such a way that the actual calculation could be carried out by means of a computer.

Evaluation of simplified water-crop yield models
TL;DR: In this paper, three simplified water-crop yield models are given, which are subsequently used for the analysis of a large number of reported irrigation trials on alfalfa, sorghum and maize.
