Calibration and Testing of the FAO AquaCrop Model for Canola

Agronomy Journal, 2011
Water being a major limiting factor in crop production, prediction of the growth and yield response of crop to water is important. Field experiments were conducted in 2009 and 2010 at Wagga Wagga (Australia) to calibrate and validate a water productivity model AquaCrop for canola (Brassica napus L.). The calibrated model was able to accurately simulate

Using AquaCrop to derive deficit irrigation schedules

Agricultural Water Management, 2010
Straightforward guidelines for deficit irrigation (DI) can help in increasing crop water productivity in agriculture. To elaborate such guidelines, crop models assist in assessing the conjunctive effect of different environmental stresses on crop yield.

The AquaCrop model

FAO (the Food and Agriculture Organization of the United Nations) launched in 2009 the dynamic crop growth model “AquaCrop” to predict yield response to water of herbaceous crops. After a brief description of the calculation scheme and the input requirements, the chapter discusses the parametrization of AquaCrop for crops and the simulation of the ...

Modified AquaCrop-OpenSource tool for data-scarce regions

2022
<p>The Food and Agriculture Organization (FAO) AquaCrop model has demonstrated its ability to accurately simulate the growth of various crops. However, the quality of simulation results depends on the calibration of the model, which in turn requires field observations of model inputs and parameters.

Assimilation of Sentinel-1 Change Detection in the Aquacrop Model: Case of Sugarcane

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The “Compagnie Sucriere Senegalaise” (CSS) wanted to upscale the field-level crop simulation model AquaCrop (FAO's agro-meteorological model) for the automated monitoring and management of its ±13.000 ha of irrigated sugarcane. A recently developed changepoint detector was applied to Sentinel-1 time series to identify key phenological crop stages for ...

Evaluation of AquaCrop model of cucumber under greenhouse cultivation

The Journal of Agricultural Science, 2020
AbstractWater consumption in agriculture is impossible without considering relations between water, soil and plant. In this regard, there are various models and developed software in order to evaluate relation between soil, water and crop growth stages. These models can be used for irrigation planning if properly optimized and applied.

AquaCrop assets and regional applications

AquaCrop is a relatively simple crop model with a wide range of applications at the point, field, and regional to continental scales. Its four main assets, distributed by FAO (https://www.fao.org/aquacrop/en/), are: (i) the standard program with a graphical user interface (GUI), (ii) the open-source version-controlled Fortran90 code available on GitHub,

Irrigation Scheduling Optimization for Cotton Based on the AquaCrop Model

Water Resources Management, 2018
To improve irrigation efficiency, it is important to optimize agriculture irrigation scheduling. The objectives of this study were to evaluate the AquaCrop model for its ability to simulate cotton in the North China Plain and optimize irrigation strategies. The AquaCrop model was calibrated using 2002–2009 data and validated using 2010–2014 data.

Calibration and validation of AquaCrop for pearl millet (Pennisetum glaucum)

Crop & Pasture Science, 2016
Pearl millet (Pennisetum glaucum (L.) R.Br.) is widely grown in some of the driest regions of the world, mainly drier tropics. Although it is easy to cultivate under semi-arid and arid regions, it still responds very favourably to slight improvements in growing conditions such as supplementary irrigation.

Simulating Yield Response of Quinoa to Water Availability with AquaCrop

Agronomy Journal, 2009
The modeling of yield response to water is expected to play an increasingly important role in the optimization of crop water productivity (WP) in agriculture. During 3 yr (2004–2007), field experiments were conducted to assess the crop response to water stress of quinoa (Chenopodium quinoa Willd.) in the Bolivian Altiplano (4000 masl) under different ...
