Abstract
Context: Energy production from energy cane biomass reduces the emission of polluting gases into the atmosphere, while the juice can be used to produce molasses and alcohol.
Objectives: The objective of this research was to determine the potential of the cultivar ‘C90-176’ for obtaining bagasse and juice at different planting and harvesting times, including the non-harvest period.
Methods: A split-strip plot design was used, with 25 treatments and five subplots. Five planting dates were combined with five harvest times. In the plant cane and first ratoon harvests, agricultural yield, bagasse and juice production, fiber and dry matter content, Pol in cane, Pol in juice, and purity were determined.
Results: In the first harvest, plantings aged 15 to 16 months, from September to December, yielded higher yields than those obtained during the harvest season, with an increase of 10.38 t of bagasse ha⁻¹. In plant cane, the highest juice yields were obtained in September, with 93,690 kg juice ha⁻¹. In ratoons harvested at 12 months during the non-harvest period, the average yield was 27 t bagasse ha⁻¹ and 32,797 kg juice ha⁻¹, with 67.7% purity.
Conclusions: The cultivar ‘C90-176’ shows potential to produce high volumes of biomass at any time of the year. Its harvest can begin during the non-harvest period and subsequently be extended until rainfall and soil moisture conditions allow.
