Generally, in a village we need to know between the crops grown by the farmers which of them are staple crops. But, there is for the moment no specific methodology for that. That's why I would like to establish a specific methodology for staple crops identification. For, all the crops grown in a village cannot be called staple. I want to know if there are some indices (quantitative data) with which we can deduce that in a considered village this crop is staple crop or not.
