The questions of what crops should be grown and how they should be used are never completely answered. Furthermore, there is no document or person that can provide all the answers desired. Agriculture always involves trial and error, experimenting and risking, learning and adjusting. These charts supply you with information to help you in making choices about which crops to try in your location. Crops are compared by categories to permit selection based on knowing how the crop can tolerate the conditions in your area. These comparison charts complement ECHO's catalog of "Seeds Available from ECHO," although the charts include a broader range of crops than offered in the catalog. It serves as another basic source of imformation on the most important crops of the tropics.
