Controle químico da tiririca (Cyperus rotundus), com e sem cobertura do solo pela palha de cana-de-açúcar Planta Daninha
Durigan,J.C.; Timossi,P.C.; Leite,G.J..
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...

Evaluation of soil management and use in an ultisol in a Guava orchard in comparison with a sugarcane field and native forest area. Repositório Alice
SOUZA, W. J. O.; SOUZA, H. A. de; ROZANE, D. E.; NATALE, W..
Abstract: Studies to find out alternative inputs are important for sustainable agriculture. In this respect, the use of byproducts from guava processing can partially replace the requirements of mineral fertilizer and add organic matter to the soil, increased water retention capacity and mitigating the effects of traffic on the soil. The aim of the present study was to assess the physical aspects of the soil in function of fertilization of guava trees with organic and mineral fertilizers and to compare the results with those found in areas of sugarcane and native forest. The soil samples were obtained from a commercial guava orchard planted with the ?Paluma? (8 years) and ?Pedro Sato? (5 years) cultivars, vegetatively propagated, as well as from a cane...

Growth of pre-sprouted sugarcane seedlings submitted to supplementary lighting AGRIAMBI
Almeida Neto,Luiz A.; Guiselini,Cristiane; Menezes,Dimas; Cordeiro Júnior,José J. F.; Pandorfi,Héliton.
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...

Plant growth, radiation use efficiency and yield of sugarcane cultivated in agroforestry systems: An alternative for threatened ecosystems Anais da ABC (AABC)
SCHWERZ,FELIPE; MEDEIROS,SANDRO L.P.; ELLI,ELVIS F.; ELOY,ELDER; SGARBOSSA,JAQUELINE; CARON,BRAULIO O..
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...

Soil management of sugarcane fields affecting CO2 fluxes Scientia Agricola
Tavares,Rose Luiza Moraes; Siqueira,Diego Silva; Panosso,Alan Rodrigo; Castioni,Guilherme Adalberto Ferreira; Souza,Zigomar Menezes de; Scala Jr.,Newton La.
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...
