An overview of the history and the process of modeling studies of field crops in Iran

Evaluation of the each subject on the basis of evolutionary process would be helpful to more insights and to make better decisions. In this regard, crop modeling has no exception. In order to study the process of modeling of crops in Iran, 162 resources includes articles, theses and books was investigated. Studies showed that the first model in 1998 was developed on the effect of soil properties on yield of chickpea under rainfed conditions. The results showed that grain yield and wheat with 49 and 38 replication, highest adjective and plant were measured, respectively. Non-linear regression with 25 replications was the most widely used models. The most of the reference belonged to articles with 129 cases. The maximum study was conducted in 2011 with 24 replications, two researchers had the greatest role in the development of crop modeling and the most application of the model was used in the discussion of crop management. Finally, it can be concluded that, modeling has been used in different cases of crops in Iran and this can be a good supplement to other methods of research
