Crop File (.CIN)
The Crop file stores parameters for the prediction of relative yields for a crop. Information such as planting dates, growing season, root depths, and weir settngs are stored in this file. Changes to the .CIN file can be done under the Manage Input Data > Crops section.
A DRAINMOD simulation can be run without specifying a crop file. In this case, the following parameters are entered in the Manage Input Data > Crops section.
Rooting Depths
SEW
Trafficability Inputs
Crop relative yields can be simulated in DRAINMOD by including a .CIN file. The equation used by DRAINMOD for computing crop relative yields is
YR = Y/Yo = YRp * YRw * YRd
where YR is the relative yield, Y is the yield for a given year, Yo is the optimum long term average yield, YRp is the relative yield that would be obtained if only reduction due to planting date delay is considered, YRw is the relative yield if only reductions due to excessive soil water conditions are considered and YWd is the relative crop yield if the only reductions are due to deficient soil water.
Additional parameters associated with the .CIN file include the following.
Planting Delays
Excess Soil Water Stress
