The type of damage selected depends upon the type of damage data that can be collected Number 1 Absolute Daily Damage is useful when pest population data can be collected If pest populations and feeding rates are known daily damage to coupling points can be computed in units of mass per unit area Number 2 Percent Observed Damage typically occurs when observations of plant components are compared between some scientific treatment and control For example defoliation can occur in one treatment resulting in a percent differ ence in leaf mass between a treatment and control In this case the source of DSSAT v3 Volume 2 DSSAT v3 Volume 2 DSSAT v3 Volume 2 DSSAT v3 Volume 2 DSSAT v3 Volume 2 DSSAT v3 Volume 2 DSSAT v3 226 Crop Models DSSAT v3 Volume 2 Crop Models Crop Models Crop Models Crop Models Crop Models Crop Models Crop Models Crop Models Crop Models Crop damage may not be known while time series measurements describing the per cent reduction between treatment and control is known Number 3 Daily Percent Damage rate is useful when damage can be measured as percent on a daily basis For instance in a manual defoliation study 33 percent and 66 per cent defoliation may be applied on a particular day during the season In this case damage is applied as a percent daily damage Another example would be the application of a shade cloth that blocks 80 perce

EXP LST and experiment data file FILEX While reading these files the input module displays various screens including those for experiment and treat ment selection options When a user has selected and or modified the options available in the sensitivity analysis section a temporary file is written Control is given back to the model driver and the simulation module is called IBSNAT30 INP The simulation module does not provide any interaction with the user instead it reads the temporary input file simulates growth over a sea son and outputs simulation results on the screen Upon completion of a simula tion control is returned to the model driver and a user can then choose to run another simulation run or terminate the simulation The format of the temporary file IBSNAT30 INP is discussed later in this chapter COMPONENT STRUCTURE Crop DRIVER Because the crop model driver was developed to control the calling of the input and the crop simulation modules all EXE files need to be located in the same directory for the system to work properly Figure 2 Typically this would be the C NDSSATS directory The models however can be run from any data directory as long as the path where the EXE files are located is specified To run a model the driver is executed from the directory containing input data and the names of the input module and the crop module are specified as command line arguments The default syntax is the fo

Crop Models Crop Models Crop Models Crop Models Crop described by Curry et al 1990 For the CROPGRO model when the hedge row photosynthesis model is selected is used to modify the leaf assimilation rate in a more mechanistic way with an adaptation of the Farquhar et al model by Pickering et al 1993 CLIMATE CHANGE STUDIES The DSSAT v3 crop simulation models have the capability to modify daily weath er data read in from the weather file as well as photoperiod daylength Each weather variable can be modified by multiplying a constant times the input value and or by adding a constant to it This provides flexibility to change one or all weather variables and includes the capability to set them to constant val ues similar to conditions as observed in growth chamber and other constant envi ronment experiment studies Users can specify the date that a given modification is to begin and can also define more than one entry if the experiment includes environment switching of any type These options are included in a special envi ronmental section of FILEX for any experiment and can also be changed interac tively during any model run W EATHER GEN ERATO RS The DSSAT v3 crop simulation models have built in capabilities for simulating weather using either one of two weather generators Coefficients for generating weather are stored in site specific climate files e g CLI such as UFGA CLI where UFGA is the site of the
