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.

Abstract Green peas (cv.‘Victory Freezer’) were grown at five plant densities (52, 90, 105, 182, 358 plants/m2) and three soil moisture treatments: natural rainfall, irrigation at flowering and pod swelling, and water stress at these periods. Both total green yield and green pea yield increased with increasing density, although green pea yield dropped slightly below 182 plants/m2. No significant differences occurred between natural rainfall and water stress treatments. Irrigation gave an 87% inc...

The objective of this study was to evaluate the potential use of dual crop coefficient method in FAO-56 (FAO dual-Kc) and Shuttleworth–Wallace (S–W) model in estimating evapotranspiration (ET) and its components (plant transpiration and soil evaporation) of a vineyard in arid region of northwest China. Continuous measurements of ET with eddy covariance, plant transpiration (T) with sap flow system and soil evaporation (E) with micro-lysimeter in 2013 and 2014, were used to validate the performan...

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...

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...

Two contrasting rainfall barley seasons, dry (2012) and wet (2013), were used to parameterize and assess the performance of the SIMDualKc and AquaCrop models. Field data were obtained from malt barley cropped in a farmer’s field in Ribatejo, Portugal. SIMDualKc applies the dual crop coefficient approach for computing and partitioning crop evapotranspiration (ET), while AquaCrop uses an empirical approach to estimate potential crop transpiration (Tc) and soil evaporation (Es) depending upon the c...

Abstract Heat units, expressed in growing degree-days (GDD), are frequently used to describe the timing of biological processes. The basic equation used is GDD = [ (T MAX + T MIN ) 2 ]−T BASE , where T MAX and T MIN are daily maximum and minimum air temperature, respectively, and T BASE is the base temperature. Two methods of interpreting this equation for calculating GDD are: (1) if the daily mean temperature is less than the base, it is set equal to the base temperature, or (2) if T MAX or T M...

Abstract Irrigation planning and scheduling require the availability of modeling tools that are accurate, quick and easy to use. The crop coefficient ( K c )-reference evapotranspiration (ET) method is a traditional method for estimating ET, but has become relatively complicated with the introduction of the dual K c procedure. The dual crop coefficient approach ( K cb + K e ) gives a better estimation of daily crop evapotranspiration because it separately considers soil evaporation and crop tran...

The dual crop coefficient (Kc) approach to estimate crop evapotranspiration (ETc) separately considers soil evaporation (E) and plant transpiration (T) by computing a soil evaporation coefficient (Ke) and a basal crop coefficient (Kcb), respectively, with Kc=Ke+Kcb. This approach may be more precise than the single Kc approach particularly when the crops incompletely cover the ground. The SIMDualKc model, which is adopted in this study, is an irrigation scheduling simulation model that uses a da...

A generic agricultural drought index, called Agricultural Reference Index for Drought (ARID), was designed recently to quantify water stress for use in predicting crop yield loss from drought. This study evaluated ARID in terms of its ability to predict crop yields. Daily historical weather data and yields of cotton, maize, peanut and soybean were obtained for several locations and years in the south-eastern USA. Daily values of ARID were computed for each location and converted to monthly avera...

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...

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...
