“…Sucrose influenced the improvement of the raw material's quality, which is identified with the high levels of SS and purity and low levels of RS. 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 this study, the ripeners were applied at the medium maturation stage (270 DAP). Ayele et al (2023b) reported higher sucrose contents and yields in sugarcane harvested at 240 and 300 DAP, while lower responsiveness to ripeners was recorded in later applications. According to the The increase in fiber content in the NR+CR treatment probably occurred due to the need to meet the plant's metabolic demand for synthesizing different compounds, such as fibrovascular bundles.…”

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.
