“…For the percentage of reducing sugars in the juice (69.1 and 67.7%) and the percentage of reducing sugars in the cane (1.14 and 1.25%), the highest values were observed in treatments G3E2 and G3E3, respectively, indicating that increases in these attributes directly influenced low TRS contents (Figure 3A and 3B). The reducing sugars parameter is used to designate the percentage of glucose and fructose, which are precursor products of color in the sugar industrial process, i.e., they intensify the color of the sugar, and their increase promotes less efficiency in sucrose recovery, depreciating the product's quality (Prado et al, 2017;Morais et al, 2022). When evaluating the effects of water deficit in different phenophases of six sugarcane genotypes (SP79-1011, RB855113, RB92579, RB867515, RB72454, and RB855536), Endres et al (2018) found low industrial quality of sugarcane and consequently lower TRS values in RB855113.…”

Sugarcane is one of the largest agricultural commodities when considering the export volume and the number of jobs generated. Sugarcane production in the Brazilian Northeast region is generally low due to several factors, including the irregular rainfall distribution, which highlights the importance of studies aimed at mitigating the deleterious effects of water stress. In this scenario, this study aimed to evaluate calcium pyruvate as a water deficit attenuator on the agro-industrial quality of sugarcane in the second cycle of cultivation. The experiment was conducted out under greenhouse conditions of the Federal University of Campina Grande, where five sugarcane commercial genotypes tested (G1- RB863129, G2- RB92579, G3- RB962962, G4- RB021754, and G5- RB041443) and three irrigation management strategies (E1- full irrigation, E2- water deficit with application of 30 mM of calcium pyruvate, and E3- water deficit without calcium pyruvate application), distributed in randomized blocks in 5 × 3 factorial arrangement with three replications. The RB021754 genotype under water deficit and without foliar application of calcium pyruvate increased the fiber content (13.2%) and the sugarcane moist cake weight (143.5 g). The effects of water deficit in sugarcane genotypes are attenuated by the exogenous application of 30 mM of calcium pyruvate, with benefits on the polarized sucrose content, apparent sucrose content of the juice, soluble solids content, purity, corrected cane POL, total recoverable sugars, and stem mass in relation to plants under water deficit without calcium pyruvate application.

“…Barbosa et al (2013) did not verify the influence of fertigation as well with vinasse via subsurface drip irrigation on the values of total recoverable sugar during three cycles of cane growth. Prado et al (2017), when evaluating the application of four doses of vinasse (0, 450, 600, and 750 m 3 ha -1 ) using the RB 85-5453 variety of sugarcane, found that an increase in vinasse dose caused an increase in the total reducing sugar, which is desirable for the sugar and alcohol industries. The TRS is important for both the industry and producers as it is the parameter for industrial unit used to determine the price paid to the producers (OLIVEIRA et al, 2012).…”

Vinasse Application Management on Two Sugarcane Varieties in the Cerrado Goiano

Sugarcane is considered as one of the prominent agricultural crops in Brazil, with Goiás being the second largest national producer. During the processing of sugarcane, waste is generated, and one of these is vinasse. The objective of this study was to evaluate the biometric and technological performances of two varieties of sugarcane for different depths and vinasse parceling. Experiments were conducted at Fazenda Boa Sorte, located in the municipality of Carmo do Rio Verde-GO. A randomized block design was used with a subdivided plot containing two varieties of sugarcane (RB 86-7515 and SP 80-1816) and each subplot having three management types for the application of vinasse (M1 20-20 mm, M2 40-0 mm, and M3 30-30 mm) and four repetitions. The applications were performed in the months of May and June (dry period). The variables analyzed were the plant height, number of photosynthetically active green leaves, stem diameter, leaf area, stalk productivity, soluble solids content, broth pol, apparent sucrose content, fiber content, total reducing sugars, and reducing sugars. Analysis of variance was performed on the results obtained using the F test; subsequently, for the significant data, the test of means was performed. The SP 80-1816 variety showed superiority for both the biometric and technological variables. The ethanol yield and total recoverable sugar content were higher for the SP 80-1816 variety, with no difference between the vinasse application management. The vinasse application installment did not show viability.

“…According to Prado et al (2017) and CONSECANA ( 2006), the ideal amount of fiber varies between 12 and 13%, which does not compromise the available amount of bagasse for burning. The data obtained in this study are within this range considered adequate for fiber in sugarcane, a result similar to that reported by Silva et al (2014), who obtained a mean values of 12.8%.…”

“…As the N dose increased, there was a reduction in fiber content, with a difference of 5% between the lowest dose (0 kg ha -1 N) and the highest dose (200 kg ha -1 N). Prado et al (2017) state that the fiber content is of great importance in the sugarcane industry in relation to the agricultural aspect; thus, the fiber-rich varieties have greater resistance to lodging and pests. Oliveira et al (2012) report that fiber content below 10.5% is undesirable because of the energy balance in the mills, since it is necessary to burn more bagasse to maintain the calorific power in the boilers.…”

The objective of this study was to evaluate the stalk yield, sugar yield and technological quality of two varieties of sugarcane under different irrigation depths and nitrogen doses. The experiment was conducted in two consecutive years (2015 and 2016) at Olho D’Água Farm, in Itambé, Pernambuco, Brazil. The experimental design was randomized blocks in the split-split-strip-plot scheme, with four replicates. Treatments consisted of four irrigation depths (L1 = 12, L2 = 45, L3 = 100 and L4 = 125% of the crop evapotranspiration - ETc, plant cane) and (L1 = 10, L2 = 40, L3 = 100 and L4 = 125% ETc, ratoon cane), four doses of nitrogen (N1 = 0, N2 = 50, N3 = 100 and N4 = 200 kg ha-1 of N) and two varieties of sugarcane (RB92579 and RB002754). Sugarcane plants irrigated with the highest depths of 1,324.06 and 1,242.3 mm in the plant cane and ratoon cane cycles respectively produced 38.40 and 49.14 t of stalks ha-1 and 0.48 and 1.82 t of sugar ha-1 more, compared to those irrigated with the lowest depths of 124.06 and 99.4 mm. The highest stalk yield was obtained with the combination of 120.7 kg ha-1 of N and 1266.6 mm of irrigation depth. Sugarcane technological quality is positively correlated with the increase of the irrigation depth in the plant cane and ratoon cane cycles and negatively correlated with nitrogen.
