Simulation of dryland maize growth and evapotranspiration using DSSAT‐CERES‐Maize model

Agronomy Journal, 2020
AbstractEvapotranspiration (ET) is a crucial component of plant water use and ecosystem energy balance. This study aims to simulate maize (Zea mays L.) ET using a crop modeling system and compare that to ET measured using an eddy‐covariance (EC) system.

Adaptation of CERES-Maize model for a better simulation of plant population density effects

Field Crops Research, 2019
Abstract The Crop Environment Resource Synthesis (CERES) models have been developed and utilized for the last 30 years at the field scale to optimize current management, estimate crop yield potential, and study input-use efficiency. Despite a large number of simulated variables, little work has been devoted to modeling the effect of plant population ...

Yield and Nitrogen Uptake Prediction by CERES-Maize Model under Semiarid Conditions

Soil Science Society of America Journal, 1997
Abstract Quantitative relationships between N and irrigation management on crop yield and NO 3 − leaching is urgently needed for economical and environmental analyses.

Testing the CERES-Maize model in Belgian conditions

European Journal of Agronomy, 1993
Abstract CERES-Maize was tested in two years with two cultivars at Louvain-la-Neuve, Belgium. Observed values of the genetic coefficients differed between cultivars and were within the wide range of values found elsewhere in N. W. Europe for cultivars of the same precocity group.

Optimization of irrigation and fertilization of drip‐irrigated corn in the chernozem area of north‐east China based on the CERES‐Maize model

Irrigation and Drainage, 2020
To improve water and nitrogen utilization efficiency, and reduce nitrogen leaching in the chernozem area of north‐east China, field trial data and the CERES‐Maize model were used to optimize irrigation and fertilization management of drip‐irrigated corn.

Comparing genetic coefficient estimation methods using the CERES-Maize model

Agricultural Systems, 2000
Abstract Many crop simulation models use genetic coefficients to characterize varieties or hybrids. Two methods now used with CERES-Maize to obtain genetic coefficients are: (1) direct experimental measurement; and (2) estimation using the Genetic Coefficient Calculator (GENCALC), an iterative computerized procedure.

CALIBRATION OF THE CERES-MAIZE MODEL FOR LINKAGE WITH A MICROWAVE REMOTE SENSING MODEL

Transactions of the ASABE, 2005
Stored water, i.e., soil moisture in the root zone, is the most important factor governing energy and moisture fluxes at the land surface. Crop models are typically used to estimate these fluxes and simulate crop growth and development. Remotely sensed microwave observations can be used to improve estimates of these fluxes, biomass, and yield.

Evaluating a Leaf‐Level Canopy Assimilation Model Linked to CERES‐Maize

Agronomy Journal, 2005
The simple approach of calculating crop growth rate as the product of intercepted light and radiation use efficiency may not adequately represent plant growth under stress conditions. We developed a photosynthesis and respiration model for maize (Zea mays L.) and linked it to CERES‐Maize v.3.7, calling the new model CERES‐PR.

Evaluation of the RZWQM-CERES-Maize hybrid model for maize production

Agricultural Systems, 2006
The root zone water quality model (RZWQM) was developed primarily for water quality research with a generic plant growth module primarily serving as a sink for plant nitrogen and water uptake. In this study, we coupled the CERES-Maize Version 3.5 crop growth model with RZWQM to provide RZWQM users with the option for selecting a more comprehensive ...

Development of a Leaf‐Level Canopy Assimilation Model for CERES‐Maize

Agronomy Journal, 2005
Calculating crop growth rate as the product of intercepted light and radiation use efficiency may yield inaccurate predictions under stress conditions. A more mechanistic simulation of photosynthesis and respiration may be required to improve model accuracy under stresses.
