Designing an optimal crop pattern and on-time water allocation of water resources along with deficit irrigation are among the optimal solutions to maximize the water economic efficiency index. In this paper, the simultaneous optimization of crop pattern and water allocation are discussed using the deficit irrigation method. The study area is located west of the Qazvin plain irrigation network. ...

Agriculture resources reflected to be one of the most imperative renewable and dynamic natural resources. Agricultural sustainability has the premier priority in all countries, whether developed or developing. Cropping system analysis is indispensable for grinding the sustainability of agricultural science. Crop alternation is stated as growing one crop after another on the same piece of la...

The conventional method of compiling statistics on Crop Estimation is done by the Government Ministry to make ground surveys, during which selected farmers or village officials are interviewed regarding their crops. By comparison with the results of previous years, this information is then extrapolated to generate data and predictions on a regional basis. This means that these traditional surve...

At the river catchments, different strategies at the whole or different parts of the basin can be applied for water resources management. One of these strategies is optimal water allocation and crop pattern. In this study, an optimization model for water allocation and cropping pattern is presented based on the cooperative game theory. To measure the performance of the developed model, the cult...

This study aimed at analysing patterns of crop sequences over time throughout the German federal state of Lower Saxony from 2005 to 2012. Therefore, the IACS (Integrated Administration and Control System) data was analysed for the identification of spatial and temporal pattern of crops grown on farmer’s fields. Lower Saxony is a region where maize growing had a steep increase and, therefore, wa...
