PDC LESSON 1.14 PRINZIPLES ON YIELD 
The yield of a system is theoretically unlimited.
DISPERSEL OF FOOD YIELD OVER TIME
·       
By selection of early, mid, and late
season varieties 
·       
By planting the same variety in early
or late ripening situations.
·       
By selection of long-yielding
varieties.
·       
By a general increase in diversity in
the system, so that leaf, fruit, seed and root are all product yields.
·       
By using self-storing species such as
tubers, hard seeds, nuts, fuel wood, or rhizomes which can be “chopped on
demand”.
·       
By techniques such as preserving,
drying, pitting, freezing, and cool storage.
·       
By regional trade between
communities, or by the utilization of land at different altitudes or latitudes.
The only limit on the number of uses of a
resource possible within a system is in the limit of the information and the
imagination of the designer.
