Assessment of AquaCrop Model on Potato Crop in Uruguay

Agrociencia, 2015
The potato crop (Solanum tuberosum L.) is a high important crop in Uruguay. The Southern region is the most important production area of potato there. It is considered that in this region, irrigation should be supplementary since summer rainfall rarely reach crop requirements.

Evaluating Reference Evapotranspiration (ETo) Calculation Methods and Quantifying Climate‐Driven Change in Irrigation Demand Across Nepal's Terai

International Journal of Climatology, EarlyView.
Framework illustrating the comparison of different reference evapotranspiration (ETo) estimation methods and the integration of baseline ETo, crop water requirement (CWR), and irrigation water requirement (IWR) calculations with downscaled CMIP6 climate projections under SSP245 and SSP585 scenarios for the mid‐century and late‐century periods across ...

Modelling the impacts of in-field soil and irrigation variability on onion yield [PDF]

, 2013
Globally, onion (Allium cepa L.) represents an extremely important crop in terms of production, value and consumption. Similarly, in the UK onion production is considered to be one of the most important high-value field vegetables, with ca.

AquaCrop simulation for weed-infested fields

, 2016
Weed infestation is a major yield reducing factor that also decreases crop water productivity. Yet, weeds are often neglected in crop productivity simulation studies, because existing empirical equations and mechanistic models are not widely applicable ...

Intra‐Seasonal Crop Management and the Potential Benefit of Seasonal Precipitation Forecasts: Farm‐Level Embedded Risk Analysis in Ethiopia

Journal of Agricultural Economics, EarlyView.
ABSTRACT How large is the potential benefit for farmers from obtaining forecasts of total rainfall in the upcoming season? This critically depends on the local farm system and the crop management actions available to farmers to respond to the forecasts issued. Studies assessing the financial value of seasonal precipitation forecasts have so far focused

Modeling Irrigation Efficiency Paradox From Farmers' Behaviors

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Agricultural irrigation accounts for 70% of global freshwater withdrawals, highlighting its critical role in water conservation. However, numerous studies have presented the irrigation efficiency paradox, whereby increased efficiency rarely reduces water consumption.

Calibration and testing of AquaCrop for selected sorghum genotypes

Water SA, 2017
Predicting yield response to water is important in rainfed agriculture. The objective of this study was to calibrate and test AquaCrop for simulating yield of 3 sorghum genotypes (PAN8816, a hybrid; Macia, an open-pollinated variety; and Ujiba, a landrace) grown during the 2013/14 and 2014/15 planting seasons (early, optimal and late planting dates ...

Fielding Floods for Flourishing Farms: A Framework for Assessing the Reuse of Small Flood Reservoirs as Irrigation Reservoirs

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Due to the increased intensity and frequency of droughts under a warming world, agricultural irrigation demand (AID) is likely to increase in many regions of the world—not just in semi‐arid and arid regions, but also in temperate regions. Small reservoirs have often been touted as a decentralized solution to increase water supply resilience ...

Assessing Response of Water Footprint of Maize Production to Drought in China: Different Climate Scenarios and Irrigation Strategies

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Climate change impacts on water resources and drought characteristics will significantly affect regional agricultural water security. To clarify the response mechanism of water consumption and drought, this study coupled meteorological data from CMIP6 under two shared socioeconomic pathways in China.

A Regional Version of the Aquacrop Model Evaluated with Satellite Retrievals and Backscatter Data

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The current intensive use of agricultural land forces a shift to more sustainable methods of crop production. Future crop demands are expected to rise due to a strong increase in population and prosperity, and the uncertainty in crop yields is expected to increase because of changing climatic conditions.
