Abstract
Aiming at improved knowledge on water use, productivity and irrigation scheduling of processing pea, the soil water balance model SIMDualKc was calibrated and validated using field data observed in two farmers’ fields in a wet and a dry year. The model uses the dual crop coefficient approach for partitioning crop evapotranspiration into crop transpiration and soil evaporation. Calibration was performed by minimizing differences between measured and simulated soil water content with a root mean square error representing 2% of the measured mean. The calibrated basal crop coefficients for the initial, mid-season and end-season were respectively 0.15, 1.15 and 1.10. Pea commercial yield (5084–8197kgha−1), obtained from the total yield using industry textural and quality criteria, was influenced by climatic conditions and the harvesting date. Using the global water-yield function with Ky=1.15 and the actual crop transpiration computed with SIMDualKc, the fresh and commercial yields were estimated with errors smaller than 3.5%. Water productivity relative to the commercial yield varied 1.51–2.67kgm−3, mainly depending on the yield achieved rather than on water use. Results from the economic water productivity ratio (EWPR), which compares the commercial yield value with the corresponding production costs, varied 1.07–1.82. Because irrigation costs were a small fraction of the total costs, EWPR values mainly varied with the commercial yield and less with irrigation costs. Irrigation scheduling alternatives for wet and dry years showed that water saving is achievable without considerably affecting peas’ yield and economic results. Results show that the SIMDualKc model is appropriate to support irrigation advising.

The AquaCrop model was parameterized and evaluated using data relative to supplemental irrigated vining pea for industry using observations in farmers’ fields located in the Ribatejo region, Portugal. Data refers to field observations relative to leaf area index (LAI), soil water content, biomass and final yield relative to two contrasting rainfall years, 2011 and 2012, a wet and a dry year, respectively. LAI data were used to parameterize the canopy cover (CC, %) curve. Results showed that afte...

The previously field calibrated approach of coupling the SIMDualKc soil water balance model with the Stewart’s water-yield model was used to assess the impacts of alternative sowing dates and irrigation schedules upon malting barley (Hordeum vulgare L. cv. Publican) yields. To properly support modelling, the study was based upon field observations in a farmers’ field during 2012 and 2013 crop seasons, respectively a dry and a wet year. The study aimed at assessing alternative sowing dates and ir...

Soil salinization is an increasing threat in agricultural water scarce regions, where even saline irrigation waters can be seen as an important resource. The sustainable use of these waters requires a precise knowledge of the processes involved, with modeling assuming a critical role in irrigation water management. The objective of this study was to develop and test an empirical approach for considering the effect of transient salinity stress on maize and sweet sorghum transpiration rates estima...

Various maize irrigation treatments including full and deficit irrigation were used to calibrate and validate the soil water balance and irrigation scheduling model SIMDualKc at Paysandu, western Uruguay. The model adopts the dual crop coefficient approach to partition actual evapotranspiration (ETc act) into actual transpiration (Tc act) and soil evaporation (Es). Low errors of estimation were obtained for simulating soil water content (Root mean square errors (RMSE) ≤ 0.014 cm3·cm−3 with calib...

In arid and semi-arid countries, the use of irrigation is essential to ensure agricultural production. Irrigation water use is expected to increase in the near future due to several factors such as the growing demand of food and biofuel under a probable climate change scenario. For this reason, the improvement of irrigation water use efficiency has been one of the main drivers of the upgrading process of irrigation systems in countries like Spain, where irrigation water use is around 70 % of its...

Estimation of field crop evapotranspiration (ETc) and its partitioning into evaporation and transpiration, are of great importance in hydrological modeling and agricultural water management. In this study, we used a dual crop coefficient model SIMDualKc to estimate the actual crop evapotranspiration (ETc act ) and the basal crop coefficients over a cotton field in Northwestern China. A two-year field experiment was implemented in the cotton field under mulched drip irrigation. The simulated ETc ...

The HYDRUS-1D and HYDRUS (2D/3D) computer software packages are widely used finite-element models for simulating the one- and two- or three-dimensional movement of water, heat, and multiple solutes in variably saturated media, respectively. In 2008, Simůnek et al. (2008b) described the entire history of the development of the various HYDRUS programs and related models and tools such as STANMOD, RETC, ROSETTA, UNSODA, UNSATCHEM, HP1, and others. The objective of this manuscript is to review selec...

Wheat is one of the crops occupying the largest areas in the world (218 million ha in 2013). Understanding the land–atmosphere energy exchanges over these croplands becomes important not only for agronomy but also for climatic and meteorological aspects. This study continues previous work on the estimation of actual evapotranspiration (ET) and the assessment of crop coefficients of sorghum, sunflower, or canola. Two variations of a simple two-source energy balance (STSEB) approach were used in c...

An accurate estimation of crop evapotranspiration (ETc) in greenhouses is critical for precise water resource management and effective irrigation scheduling. In this study, the SIMDualKc model was calibrated and validated with the data from a four-season experiment to estimate the ETc of hot pepper grown in a greenhouse located in Northwest China. Various indicators have shown good agreement between the simulated ETc through SIMDualKc model and observed throughout the seasons with regression coe...

Abstract In order to improve water management in Populus tomentosa plantations, the variation in the FAO-56 parameters of the basal crop coefficient ( K cb ) and soil evaporation ( E s ) in mature P . tomentosa plantations under different soil water availability treatments were investigated over two growing seasons. Empirical models for predicting E s in well-watered drip irrigated stands were constructed and validated. Changes in the relationship between K cb and leaf area index (LAI) during th...

Data relative to two soybean seasons, several irrigation scheduling treatments, including moderate and severe deficit irrigation, and rain-fed cropping were used to parameterize and assess the performance of models AquaCrop and SIMDualKc, the latter combined with the Stewart’s yield model. SIMDualKc applies the FAO56 dual crop coefficient approach for computing and partitioning evapotranspiration (ET) into actual crop transpiration (Tc act) and soil evaporation (Es), while AquaCrop uses an appro...
