The objective of the study is to modify the crop properties on the basis of regional conditions and to evaluate produced biomass and crop yield production by the simulation model. The evapotranspiration of study area is calculated on daily basis using model which is based on PenmanMonteith equation. The average evapotranspiration of 13 years from 2000 to 2012 is found to be 2606.2mm/year. The specification of conservative crop parameters and tuning of non conservative crop parameters for model, the crop files were created on the basis of actual field conditions. The study concludes year wise yield production of Soybean by using model and actual available data of yield production of Ujjain district in Madhya Pradesh. The average yield of Soybean for 13 years calculated by the model is 1.052 ton/ha and data available from the department of land records Ujjain is 1.003 ton/ha which is very close to simulated data. And Nash-Sutcliff efficiency of simulated and actual data comes as 0.687 and root mean square error as 0.19 and coefficient of determination is found to be 0.773 which shows that model calculates satisfactory results and can be used for the departmental purpose for the calculation of yield production.
