One of the major strategies to enhance sugarcane and sugar productivity in the sub-tropical India is to select elite sugarcane clones having high sucrose content and a longer tillering duration for commercial cultivation and their scientific harvesting schedule. A study was conducted at The Uttar Pradesh Council of Sugarcane Research, Shahjahanpur to assess the sucrose content of five early maturing and five mid-late maturing varieties. The varieties were harvested from the month of early crushing (October) to late crushing (April). The early varieties, CoS 8436, CoS 08272,CoSe 8231, Co 0238, and Co 0118 showed high percent sucrose, percent fibre and pol percent in cane in comparison to the mid-late varieties CoS 767,CoS 97261,CoS 08279,CoS 07250, and CoSe 01434. Percent juice sucrose of early maturing varieties was 12.9-16.9% during October, and gradually increased until April where the range was 20.1-21.2%. The sucrose percent in juice of mid-late maturing varieties was 13.5-14.7% in October, and increased to 18.9-19.7% in April. Although, the overall superiority of the early maturing varieties continued throughout the harvesting period and the mid-late maturing varieties showed promising performance equivalent to early maturing varieties from February onwards. Values for Pol percent cane showed a similar trend. Percent fibre of the early varieties was 12.4-13.2%, and increased by an average of 1.5 units by April in all the varieties. In mid-late maturing varieties, the percent fibre was 13-13.3% in October, and increased by 0.5-1.0 units by April. These results show that proper balance of the area under early and mid-late maturing varieties and their scientific harvesting schedule will improve sugar recovery in this part of the country.
