Formula for Economic Evaluation of Crop Sequence Systems : The general formula for economic evaluation from the perspective of crop intensification

The general formula for economic evaluation of crop sequence and relay intercropping systems from the perspective of crop intensification has been established on the basis of biological and economical parameters . This formula has possibilities for evaluating all the crop sequence and relay intercropping systems because it has included the factors that intervene in the agriculture process . It is considered one of the features proposed equivalences that can predict how the success or failure of the proposed system through price policy of inputs on the market . So, the spread of the implementation of the proposed programs in pursuing the market prices can be monitored . In order to clarify the importance of the equation used in the text, it had been begun to explain the crop sequence and relay intercropping systems and their practices as well as numerical examples were done in this book . The factors which are influential on the system choice for succession and The agricultural growing seasons in the world have been mentioned too.
