“…Many factors can influence sugarcane regrowth, such as soil temperature and moisture, the genetic background, plant age and health, and agricultural practices (Zambrosi et al 2017). Sugarcane regrowth is also influenced by straw left in the field after mechanized harvesting (Bernache et al 2020;Kroes and Harris 1996;Manhães et al 2015).…”

The root system is essential for sugarcane regrowth and the vigor of ratoon cycles as it represents the unique source of carbon skeletons and energy for the initial plant development. However, root system dynamics after shoot harvesting and its role in sugarcane regrowth remains poorly known. Here, it was hypothesized that sugarcane plants with small volume of root system will accumulate less biomass after shoot harvesting than plants with larger volume and that such regrowth is dependent on root reserves. In sugarcane plants grown in nutrient solution, shoots were cut, and two root treatments were established: reference plants with the entire root system (100%); and plants with half of the root system (50%), randomly removing half of root system. After 37 days of shoot harvesting, plants with the entire root system showed higher shoot, root and total dry mass, root length, root diameter, root area and root volume, when compared with those with 50% of the root system. Sugarcane plants with the entire root system had higher root content of starch, soluble sugar and nonstructural carbohydrates as compared to plants with 50% of the root system. A significant positive correlation was found between the variation of shoot dry mass and the variation of root nonstructural carbohydrates. Interestingly, this data revealed a disproportionate effect of root system size on sugarcane regrowth, with plants with the entire root system accumulating almost three times more biomass than plants with half of the root system during regrowth.

“…A colheita mecanizada da cana-de-açúcar apresenta desafios em termos de pesquisa e desenvolvimento, com vistas à racionalização dos recursos empregados, otimização da vida útil dos canaviais e redução de impactos ambientais (VOLTARELLI et al, 2018;BERNACHE et al, 2020;MARTINS et al 2021). Para Lanças et al (2021) a realização de ensaios com máquinas em condições controladas, propicia a geração de informação e o aprimoramento da qualidade dos processos agrícolas.…”

The base cut of cultures is one of the most studied parameters, and the variables involved in this process should be better evaluated under controlled conditions. The aim of this study was to evaluate, using an electromechanical device, under controlled conditions, the influence of the cutting angle and the machine's translation speed on the impact force generated on sugarcane stalks in mechanized harvesting. The study was carried out at the Nempa - Center for Testing of Agroforestry Machines and Tires (NEMPA) at UNESP/Botucatu. For the tests, the Sugarcane Basal Cut Testing Device (BCTD) was used. The collected data were evaluated using multiple linear regression analysis, using the stepwise method. The results showed that the angulation of the cutting blades is the most significant variable in relation to the impact force generated in the cutting process of sugarcane stalks, this research also managed to assess that the intensity of the angulation effect is more than 2 times greater than the effect generated by the displacement speed in the mechanized harvesting process.

The rapid spread of COVID-19 has a potentially significant impact on not only physical health but also psychological well-being. To the best of our knowledge, no review thus far has consolidated the psychological impact of COVID-19 across different subpopulations. A systematic search of the literature until 15 June 2020 found 150 empirical papers pertinent to the mental health consequences of the pandemic. The majority (87.3%) were from China (45.3%), the rest of Asia (22.0%) and Europe (20.0%), and mostly examined the general population (37.3%), healthcare workers (31.3%) and those with pre-existing mental and physical illnesses (14.7%). The most common psychological responses across these subpopulations were anxiety (overall range 24.8%–49.5%), depression (overall range 18.6%–42.6%) and traumatic stress symptoms (overall range 12.7%–31.6%). Healthcare workers and those with pre-existing physical and mental illnesses were more severely affected. Future studies are needed on underexamined subgroups such as the elderly and patients who recovered from COVID-19.
