Modeling surface soil and phosphorus transport using DSSAT models
, 2018 Computer simulation models are regarded as important tools to address concerns about the environmental impact of agricultural activities and have increasingly been used to complement field research. The CERES-Maize and CROPGRO-Soybean, two of the main crop growth models incorporated into the Decision Support System for Agrotechnology Transfer (DSSAT ...

Assessing Maize Yield Variability under Climate Change Using DSSAT Model
Journal of Scientific Research and ReportsCrop production is inherently sensitive to variability in climate. Temperature and CO2 are two important parameters related to climate change, affecting crop yield in a particular region. In this study, an attempt has been made to assess the impact of these two parameters on the productivity of maize crop taking sub tropical region of Jammu as study ...

Yield Predication by DSSAT Model of Wheat Crop: A Review
International Journal of Environment and Climate ChangeThe DSSAT model predicts crop productivity under different crop management scenarios and fluctuating climate circumstances, necessitating the identification of a crop cultivar's genetic coefficient. The precision with which various parameters are calibrated and validated is essential to the effective application of crop models. The model was calibrated

Análise de Sensibilidade dos Coeficientes Genéticos do Modelo Canegro/DSSAT
Anuário do Instituto de Geociências, 2017 The sensitivity analysis of genetic coefficients used in the productivity simulation of sugarcane by Canegro/DSSAT model (CD) was performed in order to identify which parameters have most relevance in the model calibration. The CD uses 20 parameters that aim to capture the differences between the varieties of sugarcane.
