Sugarcane: the evolution of technological thinking in agriculture.

The purpose of this study is to show the importance of technological progress in sugarcane production and its impact on the Brazilian economy. The evolution is shown using the time line concept to separate the most important cycles of the sugar-alcohol sector, while economic, social and environmental indicators are used to measure the results. The indicators clearly point out the sector?s progress and modernization. The study focuses on the advances achieved through the generation of new crop varieties with specific characteristics and the development of new products and byproducts of the sugarcane industrialization process. Special attention is accorded to the growth and increasing importance of the crop in the local and national economies, shown on the basis of the harvest values for the last ten years and production forecasts until 2020. The study concludes that the evolution of the agricultural and industrial technology in the recent past has enabled the sugarcane sector to become the most important and competitive in the world

Sugarcane in Brazil: current technologic stage and perspectives.

This article aims at analyzing the sugarcane culture in Brazil, showing the current agricultural and industrial development stage of the sugar-alcohol industry and how important this culture has become. It discusses its technologic evolution and the technologies that are being developed in the fields of genetic improvement and new cultural practices, and it aims at estimating the benefits that can be obtained in the next few years with the use of new varieties with specific characteristics, proper varietal management and modern cultural practices. By using data from IBGE (the Brazilian Institute of Geography and Statistics), the productivity of Brazil and of the North, Northeast, South- East, Middle-West and South regions of the country were estimated based on the genetic potential from new varieties and on the use of new cultural practices. Using information from the results of the agricultural research, it was possible to conclude that a significant raise of sugarcane productivity levels in Brazil, due to genetic improvement, is bound to happen in the next few years.Na publicação: Eliseu Alves
