“…It is followed by Degrees 3, 4 and 1, respectively corresponding to 27%, 14%, and 10% of the ratoons. Similarly, [19] found Degree 1 (no damage) in lower quantity and Degree 2 in higher quantity, respectively corresponding to 10% and 42% of the ratoons studied by the author with the Case A8800 harvester in Campos dos Goytacazes/RJ. That means that the type of damage found in greater quantity was of peripheral damages, while the degree of no damage was found in lower quantity, in only 10% of the ratoons.…”

Sugarcane is a major Brazilian agricultural product. The area cultivated in the state of Rio de Janeiro for the 2011-12 crop was of 41.31 thousand hectares. The process of mechanized harvesting of the crop still has many visible losses of raw materials caused by several factors. This study aimed at evaluating the visible losses of sugarcane and ratoon damage using the Case A4000 harvester and was conducted in the municipality of Campos dos Goytacazes, in the state of Rio de Janeiro, Brazil. The materials left on the field by the harvester were collected in six ratoon cane rows, with a length of 350 m, setting the frame sampling to every 50 m. The sampling area consisted of 20 m 2 , with eight repetitions. The losses were calculated in t•ha −1 and in %. The comparison of averages was performed by using the confidence interval, constructed by statistical "t" at 5% probability to compare the types of losses. The estimated productivity of the area was of 54 t•ha −1. The differences between the types of losses were significant. The billets and splinters were found in greater quantity.

The aim of this study was to evaluate the visible loss of sugar cane and the damage to the knuckles, using the John Deere 3520 harvester on three different travel speeds (3.0; 4.0 and 5.0 km•h −1 ), in DIC with five repetitions in Campos dos Goytacazes, Rio de Janeiro/Brazil. Each treatment was composed by six lines of harvested cane stumps, with a length of 290 m each. In these six lines, the remains of sugar cane left in the field were collected by placing the sampling frame in two central lines every 50 m, and separating 40 m of edge. The sampling area was surrounded by 2 m wide and 10 m long, totaling 20 m 2 . To calculate the damage to stumps, a visual methodology by [1], was used, which classifies the damage grade, ranging from 1 to 4. Fifty stumps were assessed randomly for each speed, in a sampling area of 1800 m 2 . The data were submitted to ANOVA and Tukey test at 5%, in order to compare the effect of different speeds on the losses and damages. There was no significant difference regarding the loss or damage by comparing the different speeds. Therefore, it is more advantageous to use the speed of 5.0 km•h −1 , harvesting more in less time and causing the same level of damage.

“…Unburned harvesting can cause damage to the base of the plant, which significantly reduces sprouting and facilitates pest and disease attacks [16][17][18]. During unburned harvesting, sugarcane damage can occur to the plants, such as uprooting, root disturbance, and stem trampling, which can be a major cause of reduced production and a decline in product quality [19][20][21].…”

Mechanized harvesting operations promote a series of benefits to sugarcane production but are also a cultivation step responsible for developing a series of problems for the soil and the plants due to plant mechanical damage, resulting in a decline in production over successive cycles due to row gaps emergence. The objective of this study was to evaluate the impact of burned and unburned harvesting systems on the occurrence of sugarcane row gaps over annual harvests. For this study, a burned and an unburned area were selected. The row gap number and length (sum of gaps, m) were measured after the sugarcane planting and plant-cane cultivation stages and after the first, second, and third sugarcane ratoon harvests. The results revealed that there was no difference in the number and length of row gaps between the burned and unburned harvesting systems. However, the row gap number and length considerably increased after the second harvest in both treatments (burned and unburned). The row gap number and length were close to 5 and 1–5 m at the planting and plant-cane cultivation stages and increased to around 60 and 70 m as the harvest progressed, respectively, in burned and unburned harvesting. Our results suggest that row gaps in sugarcane fields are independent of the burned or unburned sugarcane harvesting system but increase as the number of harvests increases.
