“…The increase in sucrose content in treatments with ripeners probably occurred due to the reduction in the demand for growth organs, which ended up leading to the accelerated accumulation of sucrose in the stalk (Ayele et al, 2023b). Similar to this study, previous studies confirmed increased sucrose content due to trinexapac-ethyl treatment (Ayele et al, 2021;2023a).…”

In irrigated fields, sugarcane’s vegetative growth and carbohydrate consumption during ripening require ripener management options to improve crop yield. The hypothesis is that ripeners, together with nutrients, biostimulants, and amino acids, improve physiological responses that favor the quality of the raw material and increase the sucrose content. Consequently, the study aimed to evaluate the agro-industrial response of a fertigated sugarcane crop to ripening agents. The treatments consisted of applying chemical ripener (CR), nutritional ripener (NR), and a joint application of NR+CR, besides control with four replicates. Agro-industrial attributes (total soluble solids, apparent sucrose (AS), reducing sugars (RS), total recoverable sugar (TRS), purity, fiber, sucrose in the stalk (SS) were evaluated at 0 (before application), 12, 19, 36, and 60 days after application (DAA). The time modified the technological attributes of sugarcane under ripener application. The highest apparent sucrose and total soluble solids values were obtained with NR+CR compared to the control. The NR and NR+CR treatments presented the highest TRS contents (150 kg Mg-1) at 36 DAA. Furthermore, the NR+CR treatment increased fiber content but did not compromise the quality of the raw material, and it showed high contents of SS and purity percentage, as well as low contents of RS. The chemical and nutritional ripeners efficiently promoted sugarcane ripening in areas without drying off before harvest. NR application at the end of the cycle can potentially increase sugar yield.

“…A practical way to surmount the issue is using a chemical ripener (CR). Preceding studies have proven a rise in sugarcane sucrose content along with CR application [5,6]. CR can be applied to sugarcane that is physiologically immature or confronts delayed maturity for various reasons, such as the conditions of exaggerated nitrogen and water [7,8].…”

Sugarcane is often harvested at non-optimal maturity. Chemical ripeners (CRs) could be a solution, although they risk killing subsequent ratoon plants (SRPs). This research aimed to unravel glyphosate (Gly) and bispyribac sodium (BS) impacts as CRs on sugarcane maturity and SRPs’ growth. The research was conducted in Kebon Agung Sugar Mill, Malang, East Java, Indonesia, from May to July 2022, using the ten-month-old Bululawang variety and was sprayed with a drone. A randomized block design was used with four treatments, i.e., Gly 1,000 mL ha-1, BS 200 mL ha-1, BS 100 mL ha-1, and control. Results showed that BS 200 mL ha-1 led to a greater rise in Cane Content Sugar (CCS) and Sugar Cristal Yield (SCY) than BS 100 mL ha-1 and the control but was still lower than Gly 1 l ha-1. The best harvest time for optimal maturity was six to eight weeks after applying BS 200 mL ha-1. The highest gap was in Gly, i.e., 45% than control and can potentially lower SCY more than other CRs, while the gaps in the 100 and 200 mL ha-1 BS were 7.82% and 11.97%, respectively. The results suggest that low doses of Gly and BS can boost maturity and also avert SRPs’ death.
