| Objetivou-se neste trabalho avaliar a eficácia e seletividade da mistura comercial pronta de trifloxysulfuron-sodium + ametryne (1.312,5 e 1.500 g ha-1), em comparação ao halosulfuron (112,5 g ha-1), MSMA (2.400 g ha-1), 2,4-D (1.675 g ha-1), sulfentrazone (700 g ha-1) e imazapic (105 g ha-1), além das testemunhas infestada e capinada, no controle de tiririca (Cyperus rotundus) em um canavial, com e sem cobertura do solo com a palhada da cana remanescente da colheita. A palhada de cana reduziu a infestação, porém não evitou grandes densidades das plantas de tiririca. O número de tubérculos inviáveis foi superior a 50% nas áreas onde se aplicou a mistura pronta (1.312,5 e 1.500 g ha-1), apesar do controle apenas regular (41,3 a 67,5%) das manifestações... |

| ABSTRACT Brazil is the largest producer and exporter of sugarcane in the world, and the sugar and ethanol sector has invested in the development of new technologies and methods of planting to meet the market demand. Thus, the aim of this study was to evaluate the performance of sugarcane at the acclimation phase and under field conditions, from pre-sprouted seedlings exposed to supplementary lighting, through light-emitting diode, in the period of acclimation in a greenhouse. The experiment was carried out in Carpina, PE, Brazil, from January to September 2017. The experimental plots were composed of pre-sprouted seedlings acclimated in greenhouse, exposed to the supplementary lighting systems, 90% Red + 10% Blue (R:B 90/10), 80% Red + 20% Blue (R:B... |

| Abstract Sugarcane (Sacharum officinarum L.) monocropping has had a great socio-economic and environmental impact in Brazil, and agroforestry systems have been considered as an alternative for more sustainable production; however, there is a lack of field research under such conditions. The aim of this study was to evaluate the growth rates, radiation use efficiency and yield traits in sugarcane cultivated in the understory of Aleurites fordii, in two agroforestry arrangements and monocropping systems. A field experiment was conducted from July 2015 to June 2016 in the city of Frederico Westphalen, Rio Grande do Sul, Brazil. The radiation use efficiency, assimilate partitioning, leaf area index, absolute growth rate, net assimilation rate, number of... |

| ABSTRACT The harvesting system of green sugarcane, characterized by mechanized harvesting and no crop burning, affects soil quality by increasing the remaining straw left on the soil surface after harvesting, thus, contributing to the improvement of physical, chemical, and microbiological soil attributes, influencing CO2 fluxes. This study aimed to evaluate CO2 fluxes and their relation to soil properties in sugarcane crops under different harvesting managements: burned (B), Green harvesting for 5 years (G-5) and Green harvesting for ten years (G-10). For this, a 1 ha sampling grid with 30 points was installed in each area, all located in the Northeast of São Paulo State, Brazil. In each point, CO2 fluxes were measured and the soil was sampled to analyze... |
