Comparative analysis of the productivity of sugar cane harvested in the Cauca river valley geographically in a period defined by the user, according to wit, agroecological zone, variety cane harvest age or number of court.

This tool will query the database for commercial production to generate graphics known as Isoproductivity curves. The curves are constructed with equal values tons of sugar per hectare - TAH (axis "z") based on different combinations of tons of cane per hectare - TCH (axis "y") and sugar yield (axis "x").

The system also generates:
Isomonth curves, where there are tons of sugar per hectare-month (TAHM) from the tons of cane per hectare-month (TCHM) and the sugar yield.

Isochronoproductivity curves, which observed the TAHM from TAH and the ages of harvest months.
