Use of models to simulate crop production has become important in optimizing irrigation management in arid and semiarid regions. However, applicability and performance of these models differ across regions, due to differences in environmental and management factors. The AquaCrop model was used to simulate soil water content (SWC), evapotranspiration (ET), and yield for grain sorghum under different irrigation regimes and dryland conditions at two sites in Central and Southern High Plains. Prediction error (Pe), estimated as the difference between simulated and measured divided by measured, for SWC ranged from −17% to 4% in fully irrigated, −3% to −10% in limited irrigated, and −16% to 25% in dryland treatments. The Pe within ±4%, −5%, and −17% to 24% were attained for seasonal ET under fully irrigated, limited irrigated, and dryland conditions, respectively. Pe values for grain yield were within those previously reported and ranged from −10% to 12%, −12% to 7%, and 9% to 17% for fully irrigated, limited irrigated and dryland conditions, respectively. Overall performance of the AquaCrop model showed it could be used as an effective tool for evaluating the impacts of variable crop and irrigation managements on the production of grain sorghum in the study area. Finally, the application of the model in the study area revealed planting date has a significant impact on sorghum yield and irrigation requirements, but the impact of planting density was negligible.

Although standardized evapotranspiration (ET) methods have been available for decades, they are commonly misunderstood, miscommunicated, and misused, especially within the agroecosystem modeling community. Some models misapply or misname standardized ET methods unbeknownst to users, and there is confusion in communication between applied ET practitioners and agroecosystem modelers. By highlighting some of these issues, we demonstrate and suggest the need for improved and consistent communication and application of standardized ET methodology.

A modified DSSAT‐CERES model for simulating summer maize growth under film mulching

Plastic film mulching is an effective agronomic measure for increasing crop yield, and the decision support system for agricultural technology transfer (DSSAT) model is an effective tool for simulating crop growth and water management. However, the DSSAT model does not have a specific soil evaporation module for plastic film mulching. In this paper, a method for estimating soil evaporation capacity under film mulching conditions based on the small hole effect was developed and embedded in the DSSAT model. Then, considering the compensation effect of soil temperature on air temperature under the condition of film mulching, the DSSAT model was modified accordingly. The results show that the average temperature compensation coefficient for 2 yr from sowing to emergence was 0.695 ˚C, and 0.305 ˚C from emergence to jointing. The improved DSSAT model can simulate the growth of summer maize (Zea mays L.) and changes in soil water content. Compared with the original model, the average relative RMSE of the simulated and observed soil water content of the modified DSSAT model improved by 2.26 and 1.63%, respectively. The modified model can improve the simulation accuracy, which shows that the method proposed in this paper can provide an effective way for the simulation of crop growth process under film mulching conditions.
