Ratooning

Ratooning (from Spanish retoƱo, "sprout") is a method of harvesting a crop which leaves the roots and the lower parts of the plant uncut to give the ratoon or the stubble crop. The main benefit of ratooning is that the crop matures earlier in the season. Ratooning can also decrease the cost of preparing the field and planting.

This method cannot be used endlessly as the yield of the ratoon crop decreases after each cycle. Ratooning is most often used with crops which are known to give a steady yield for three years under most conditions.
