ABSTRACT
Sugarcane was one of the tropical crops to be adapted to large-scale farming. Sugarcane has been known from ancient times, long before the Christian era. The original home of sugarcane, for many years in dispute, is now believed to be New Guinea. Plant growth regulators have been used in the sugarcane industry worldwide for over two decades to increase the recoverable yield of sucrose in sugarcane. The commercial success in the prevention of flowering, followed by the application of gibberellic acid for the increase of stalk elongation which ultimately resulted in increased sugar production. Research has been successful in affecting both germination of the vegetative "seed pieces" used for propagation and on the tillering of young plants of sugarcane. The various uses of plant growth regulators will be presented sequentially, as they would be used in the development of the crop.
