To find this information, I recommend trying the following:
* Local Agricultural Departments: Contact the Department of Agriculture in Keonjhar or Odisha for data on cash crops in the Telkoi region.
* Agricultural Research Institutes: Search for agricultural research institutes or universities in Odisha that may have conducted studies on the region's agriculture.
* Online Agricultural Databases: Explore online agricultural databases, like the Food and Agricultural Organization (FAO) website, for information on crop production in the region.
Let me know if you have any other questions!
