ABSTRACT
Cane yield decline in successive ratoon is ordinary symptom in most sugarcane plantation, due to many reason especially the old paradigm i.e. ratoon cane is the residue of plant cane, so there are neglecting of maintenance such as supplying, fertilizing, irrigation, weed & pest control, etc. Sugarcane with ratoon is perennial plant, attributable by ratoon age reason (generally 4-5 year). Ratoon cane have a high yield prospect, if all agronomical technique maintained as well as best practice management done. Supplying and stubble shaving take an important role to make better population of cane. Fertilizing, weed & pest control and irrigation have a major effect in growth development of sugarcane plant to better escalation of cane yield. By using at right dosage phytohormon such as auxin, GA, cytokinin etc, tillering capacity and growing rate will be higher, but over dosage will make retarded.
