Características da cana-de-açúcar in natura e hidrolisada com cal virgem em diferentes tempos de estocagem

Our objective was to evaluate the chemical composition and in vitro digestibility of dry matter of hydrolyzed sugar cane in different storage times. We conducted the trial in the Forage Sector at UNIFENAS, campus of Alfenas (MG) in 2010. The data were analyzed as completely randomized design in factorial scheme 2 (sugar cane without lime and hydrolyzed with 1.0% of lime, basis of fresh matter) x 6 (six times of storage: 0, 24, 48, 72, 96 and 120 hours), with three replicates. The sugar cane stored without lime showed lower dry matter (DM), crude protein, neutral detergent fiber and acid detergent fiber contents compared to hydrolyzed sugar cane. However, the hydrolyzed sugar cane showed higher contents of organic matter (OM) and total digestible nutrients. We reported higher in vitro digestibility of DM and OM when the sugar cane was not hydrolyzed. This can be explaining by better chemical composition of sugar cane without lime. The storage of sugar cane without lime shows results more interesting because the chemical composition and digestibility is better than hydrolyzed sugar cane. So, we not recommended using lime on the sugar cane. Moreover, the sugar cane without lime can be stored until 96 hours after cut.

Uma análise da evolução da área plantada da cana de açúcar no estado de São Paulo nos últimos 10 anos

This paper analyzes the evolution of the sugar cane plantation area in the State of São Paulo in the last ten years. It presents a concise report about the history of this raw material in the country and describes how the sector relating to sugar cane was before the economic deregulation and what changes occurred after 1990, emphasizing the territorially expansion occurred in the State of São Paulo. The paper concludes that the expansion of the sector relating to sugar cane occurred much more territorially than through productivity gains, considering that these ganis were bigger in the State of São Paulo, and that the economic deregulation left a legate of heterogeneity in this sector

Geoprocessamento na análise da vulnerabilidade ambiental desencadeada pela monocultura de cana-de-açúcar na bacia do distrito Santa Olímpia (Piracicaba/SP)

Sugar cane production is of the utmost importance to the economy of the entire Brazil, due to its multiple utility, being used as the raw material for the manufacture of various items, particularly, sugar and alcohol. In areas of sugarcane monoculture, the appropriate management of soils and water is essential, not only for the maintenance of the quality of the environment, but also for the quality of life of the population. Among the main impacts generated by the cultivation of sugar cane, stands out the withdrawal of the riparian forest, which is essential to the balance and maintenance of the ecosystem. Before that, the present work aimed at mapping the environmentally vulnerable areas in the basin of a tributary of the Corumbataí river, located in the district Santa Olímpia, in the city of Piracicaba-SP. For the purpose, techniques were used in Geoprocessing, aiming to produce thematic maps of Slope, for the Use and Occupation of Land, of Permanent Preservation Areas (APP), Soil and Geological of the basin of interest. From these mappings, the analysis was performed multi-criteria, which resulted in the Map of Environmental Vulnerability. This mapping environmental assessment of the study area, indicating proposals of practices for the management and conservation of soil and water resources, for the purpose of improving the environmental quality of the analyzed area. In this way, the research of this nature, may help in the decision-making on the part of the governmental bodies as well as civil society

Utilização da programação por metas e análise por envoltória de dados para seleção de variedades de cana de açúcar para plantio em uma usina sucroalcooleira

Organizational change is occurring in the Brazilian agribusiness from sugar cane in recent decades. Aspects of management in this sector are being changed due to the importance of its products, especially ethanol and electricity. It is observed in the literature a lack of quantitative studies in this Brazilian sector, particularly the selection of sugarcane varieties for planting. This study proposes the use of Goal Programming (GP) with Data Envelopment Analysis (DEA) to select efficient varieties of sugarcane for planting in a sugar and ethanol milling company. The study allowed the identification of efficient sugarcane varieties. This way, it helped the company to make more reliable decisions, favoring the increase of productivity
