Research Project: Development, Validation and Verification of New Modules for Corn Model, Maizsim and Potato Model, Spudsim

Location: Crop Systems & Global Change

Project Number: 8042-61660-008-02
Project Type: Specific Cooperative Agreement

Start Date: Jun 01, 2011
End Date: May 31, 2016

The first objective is to develop new modules to partition carbon, nitrogen, phosphorous, and potassium in individual leaves, modules for simulation of leaf growth and reproductive stages and organs in corn crop. The second objective is to develop algorithms to calculate the effects of nutrient and water stress on leaf addition rates. The third objective is to determine variety related parameters for the corn and potato models.

The corn model MAIZSIM and potato model SPUDSIM are under development. These models require additional modules and algorithms to improve in order to accurately simulate these crops under arid conditions of the northwestern United States. The collaborator using the data collected under irrigated conditions of the arid northwest will develop new modules and algorithms and integrate with the MAIZSIM and SPUDSIM models. These models will be validated against field data collected under a range of environmental, soil, and management conditions using several cultivars. They will also identify and develop cultivar specific parameters.
