| The objective of this work was to evaluate the impacts of spittlebug (Mahanarva fimbriolata) attack on sugarcane quality and ethanol production. Technological and microbiological parameters of juice and fermentation process were evaluated in ten fermentation cycles and two harvest seasons. Treatments consisted of different spittlebug stalk damage levels: control, with 100% of apparently healthy stalks; medium, with 15% of damaged or dry stalks (DDS); high, with 30% of DDS; and very high, with 60% of DDS. Spittlebug attack caused significant losses in cane quality, reducing total soluble solids, sucrose content, total reducing sugars, and pH, and increasing total phenolic compounds, and total and volatile juice acidity. The fermentation process was also... |

| Com o objetivo de avaliar o efeito de sistemas conservacionistas de manejo do solo sobre características agronômicas de cultivares de amendoim com hábitos de crescimento contrastantes, foram instalados sete ensaios de campo; seis em Latossolo Vermelho eutroférrico (Ribeirão Preto, SP) e um em Argissolo Vermelho-Amarelo (Pindorama, SP), todos em renovação de canaviais colhidos sem queima prévia. Utilizou-se o delineamento de blocos ao acaso, com os tratamentos arranjados em esquema de parcelas subdivididas e quatro repetições. Os tratamentos principais foram os sistemas de manejo - convencional, cultivo mínimo e plantio direto - e os secundários, as cultivares IAC-Tatu ST e IAC-Caiapó. Não há diferença estatística para produção de vagens e grãos e número de... |

| The presence of trash from the mechanical harvest of green cane on sugarcane plantations promotes changes in the agricultural management, for example, in the mechanical cultural practices of ratoon cane in-between the rows and nitrogen (N) fertilization. The goal of this study was to evaluate the performance of sugarcane in different harvest systems, associated to the mechanical cultural practices in interrows and N rates. The study was carried out on a sugarcane plantation in Sales Oliveira, São Paulo, Brazil, with the sugarcane variety SP81-3250, on soil classified as Acrudox, in a randomized block design with split-split plots and four replications. The main treatments consisted of harvest systems (harvesting green cane or burnt cane), the secondary... |
