RB002504 - New early-maturing sugarcane cultivar

Due to the high sucrose content, RB002504 is indicated for harvesting in the early harvest period, from September to November, in the Northeastern region of Brazil. Planting on medium texture soils is recommended. The cultivar is highly responsive to ideal production environments and resistant to the major sugarcane diseases.
