Grand Growth Phase
  • Grand growth phase starts from 120 days after planting and lasts up to 270 days in a 12-month crop. During the early period of this phase tiller stabilization takes place. Out of the total tillers produced only 40-50% survive by 150 days to form millable cane.
  • Most important phase of the crop wherein the actual cane formation and elongation and thus yield build up takes place.
  • Leaf production is frequent and rapid during this phase with LAI reaching around 6-7.
  • Under favourable conditions stalks grow rapidly almost 4-5 internodes per month.
  • Drip irrigation, fertigation and warm, humid and sunny climatic conditions favour better cane elongation. Moisture stress reduces internodal length. A temperature around 30oc with a humidity of around 80% is most conducive for good growth.
