15. Acúmulo de fitomassa e de macronutrientes da cana-de-açúcar relacionadas ao uso de fontes de nitrogênio / Biomass and nutrients accumulation in sugarcane as related to nitrogen fertilizer sources
A transição do manejo de cana queimada para a colheita sem despalha a fogo dificulta o manejo da adubação principalmente em relação à fertilização nitrogenada, seja pela maior imobilização do N-fertilizante, quando aplicado sobre a palhada, ou pelas elevadas perdas por volatilização de N-NH3, já que a ureia é a principal fonte de N. O objetivo

17. Estimation of sugar cane productivity using a time series of AVHRR/NOAA-17 images and a phenology-spectral model.
Despite the economic and social importance of agribusiness in Brazil, the accurate estimation of the production of its main agricultural crops, such as sugar cane, is still a big challenge to the Country. Thus this work has the objective to assess a methodology based on the use of a phenology-spectral model proposed by Pellegrino (2001) and a time series of

18. Spatial variability of some biometric attributes of sugarcane plants (variety IACSP93-3046) and its relation to physical and chemical soil attributes.
Tests to evaluate competition between plants, in general do not consider the soil spatial variability, nevertheless, the uniformity rarely is present and can not be assumed without verification. The aim of this work was to apply geostatistics to verify the spatial variability of the soil in an experimental field near Ribeirão Preto, SP, with sugarcane varie

19. No eito da cana, a quadra é fechada : estratégias de dominação e resistência entre patrões e cortador de cana em Cosmópolis/SP / At the sugar cane field, the court is closed : domination and resistence strategies among sugarcane cutters and bosses in Cosmópolis/SP
Partindo de um estudo de caso, focalizado na Usina Açucareira Ester S.A. (localizada em Cosmópolis, interior de São Paulo), a presente pesquisa tem como objetivo central a análise do Quadra fechada, um sistema alternativo de aferição da quantidade de cana cortada, que foi implantado somente na referida usina, em 1998, após um processo de negociação

20. Calcário e gesso na semeadura do amendoim combinados com adubação boratada foliar / Lime and gypsum applied in sowuing peanut combined with boron manuring by leaf spray
Expressive part of the peanut (Arachis hypogaea) in São Paulo State has cultivated for rotation in condemned areas of sugar cane that need to be reformed, and those areas frequently have presented low micronutrients levels and low basis saturation in soil. The objective of this work was to quantify the production and the yield components of the peanut crop

21. Consorciação intercalar em linha com crotalária e feijão guandu anão na soqueira da cana-de-açúcar / Row intercropping with Sunnhemp and Pigeon Pea in the ratoon sugarcane
Two great challenges for the sugar cane agribusiness are the reduction of the investment and of the operational cost to increase the competitiveness of the sugar and of the etanol. The improvement of the chemical and physical quality of the soil in elapsing of the years of cultivation of the cane is one of the factors that contribute to win those challenges.

23. Use substrate for the axenic and pasteurized culture of the Pleurotus spp. mushroom. / UTILIZAÇÃO DE SUBSTRATOS PARA O CULTIVO AXÊNICO E PASTEURIZADO DO COGUMELO Pleurotus spp.
The culture of edible and medicinal mushrooms is carried through in different ligno-celulosics substrate in axenic or pasteurized system. The Pleurotus genera is known as mushroom oyster, shimeji or hiratake. In the first experiment they had been evaluated the vigor, mycelium growth, dry mass (g), productivity (%) and biological efficiency (%) of P. sajor-ca

24. Modelos de simulação para análise e apoio à decisão nos processos de corte mecanizado, carregamento e transporte no agronegócio da cana-de-açúcar / Simulation models for analysis and decision support in the processes of cutting, loading and transport in the agribusiness of cane sugar
In the current days sugarcane occupies an area of approximately 10,5 % of all the Brazilian agricultural land, with an estimated production for the 2008/2009 crop of 528 million t. In the sugarcane production process, the harvest highlights due its high costs, representing approximately 35% of the sugarcane production costs, besides the addition of operation
