This book was released on 1983 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: As areas sob vegetacao de cerrado representam uma das principais alternativas para o aumento na producao de cana-de-acucar, desde que sejam identificados genotipos mais adaptados a essas condicoes. Com o objetivo de estudar o comportamento de 100 variedades de cana-de-acucar, quanto ao cultivo em solos com baixo pH e alto aluminio trocavel, foram avaliados os efeitos da calagem sobre as caracteristicas tecnologicas do caldo e producao de cana, POL e acucar, assim como determinou-se o grau de tolerancia ao aluminio pelos genotipos. O experimento foi conduzido no periodo de 1979/80, na Usina Ariadnopolis, no municipio de Campo do Meio, Minas Gerais, em solo classificado como latossolo vermelho escuro. O delineamento experimental utilizado foi o de blocos ao acaso, em parcelas subdivididas com 3 repeticoes, sendo utilizado os niveis de calagem nas parcelas e as variedades nas subparcelas. No plantio da cana fez-se uma adubacao basica correspondente a 30 kg de N/ha, 120 kg de P2O5/ha e 60 kg K2 O/ha na forma de sulfato de amonio, superfostado simples e cloreto de potassio. Foram avaliadas as caracteristicas do caldo (Brix, POL, pureza e coeficiente glucosico) e de producao (numero de colmos industrializaveis/ha, toneladas de cana/ha, toneladas de POL/ha e toneladas de acucar/ha). Verificou-se que a calagem nao alterou as caracteristicas tecnologicas do caldo, assim como o numero de colmos industrializaveis. Para a producao de cana, POL e acucar o efeito de calagem foi significativo, aumentando a producao ...

Download or read book Germinação e desenvolvimento inicial da cana-de-açúcar (Saccharum spp.), influenciados pelo ambiente, tempo de armazenamento e tamanho de estaca written by C. M. dos SANTOS and published by . This book was released on 1983 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foram conduzidos, em área do Departamento de Fitotecnia da Universidade Federal de Viçosa, Viçosa, MG, no ano agrícola de 1981/82, seis ensaios independentes, constituídos pela combinação de dois tipos de mudas de cana-de-açúcar, da variedade NA 56 - 79, com 15 meses de idade, armazenadas em três ambientes, em solo Podzólico Vermelho - Amarelo Câmbico. Em todos os ensaios, o delineamento experimental utilizado foi o de blocos ao acaso, com 12 tratamentos, constituídos pela combinação de quatro tempos de armazenamento com três tamanhos de estacas (fatorial 4 x 3), com três repetições. Procurou - se estudar o efeito da redução do tamanho da muda convencional, sobre a germinação e desenvolvimento inicial das plantas de cana-de-açúcar, bem como avaliar os efeitos do tempo de armazenamento de dois tipos de mudas em três ambientes. Avaliaram - se os seguintes parâmetros: perda de peso durante o armazenamento; germinação; número de perfilhos; número de perfilhos por planta; número de colmos na colheita; vigor das plantas; sobrevivência das plantas; altura das plantas; diâmetro dos colmos; número e comprimento de colmos com internódios distintos e peso de matéria seca da parte aérea e dos rizomas. Para as condições em que foi realizado este trabalho, concluiu - se que: 1- para as mudas não armazenadas, a redução do tamanho de estaca aumentou a eficiência de germinação; 2- a resistência das mudas ao armazenamento aumentou com o tamanho de estaca, enquanto a eficiência de germinação foi reduzida, em razão do tempo em que permaneceram armazenadas; 3- o desenvolvimento das plantas oriundas de estacas com três gemas foi melhor, proporcionando maior produção de matéria seca, comparativamente às plantas oriundas de estacas com uma gema; 4- exceto quando os colmos seccionados foram armazenados em condições ambientes, o armazenamento das mudas por até sete dias não afetou a maioria dos parâmetros avaliados; 5- os resultados abtidos nos ensaios possibilitaram selecionar parâmetros importantes, que permitirão a realização de ensaios por período mais longo, correspondente ao ciclo normal da planta, visando a avaliar a produção agroindustria de canaviais originários de diversos tamanhos de estacas.

Download or read book Sugarcane Bioethanol written by Luís Augusto Barbosa Cortez and published by . This book was released on 2010 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Brazil, sugarcane ethanol supplied, in 2009, 17.6 % of the energy for land transportation (excluding railroads)and about 55% of the total energy supplied by liquid fuel for Otto cycle engines. Besides the lower production costs ethanol produced from sugarcane in Brazil has another important advantage: in Central-South Brazil only 1 unit of fossil energy is used for each 8-9 units of energy produced by ethanol from sugarcane. Carbon emissions reduction also benefits from sugarcane ethanol: for each cubic meter of ethanol used as fuel, there is net saving of around 2 t CO2 not emitted to the atmosphere while, at the same time, no SO2 is emitted. Sugarcane was introduced in Brazil in 1532. The "Brazilian model" of producing concomitantly sugar and ethanol, brought important technical benefits and made possible an outstanding increase in the competitiveness in the international market for sugar and ethanol. Today about 50% of the sucrose of sugarcane produced in the country is directed to the production of sugar while another half is used to produce Ethanol. Industrial and academic R&D has helped to increase the productivity of ethanol steadily over the past 35 years, at a rate of 3.2% per year. Productivity gains implied savings of planted area by a factor of 2.6. In 2009/2010 the area planted with sugarcane for Ethanol production was 4.2 Mha, amounting to 1% of the total arable land available in Brazil. About 60% of the Ethanol produced in Brazil comes from the State of Sao Paulo, where the productivity is the highest (around 86 t/ha.year). Most of the recent expansion is happening in the center-west region of the country, in degraded pasture lands. The FAPESP Program for Research on Bioenergy, BIOEN, aims at articulating public and private R&D, using academic and industrial laboratories to advance and apply knowledge in fields related to ethanol production in Brazil. The BIOEN Program has a solid core for supporting academic exploratory research activities that will generate new knowledge and form scientists and professionals essential for advancing industry capacity in ethanol related technologies. On top of this, BIOEN includes partnerships with industry for cooperative R&D activities between industrial and academic laboratories, which are to be co-funded by FAPESP and industry.Federal agencies, such as CNPq, will also co-fund the research.

Book excerpt: Agricultural production is related to physical constrains, which may not always be overcomed by technology. However, under the same conditions, it is possible to see well-managed farms consistently making greater profits than similarly structured, neighboring farms. For each abiotical condition, it is well-known there is a difference between the potential and observed yields, which is usually high and often could be reduced through more appropriate management techniques. In this book, we have a selection of agricultural problems encountered in different regions of the world which were addressed using creative solution, offering new approaches for well-known techniques and new tools for old problems.

Available in PDF, EPUB and Kindle. Book excerpt: Silicon, considered to be the second most abundant mineral element in soil, plays an important role in the mineral nutrition of plants. A wide variety of monocot and dicot species have benefited from silicon nutrition, whether direct or indirect, when they are exposed to different types of abiotic and or biotic stresses. Besides the many agronomic and horticultural benefits gained by maintaining adequate levels of this element in the soil and also in the plant tissue, the most notable effect of silicon is the reduction in the intensities of a number of plant diseases caused by biotrophic, hemibiotrophic and necrotrophic plant pathogens in many crops of great economic importance. The aim of this book is to summarize our current understanding of the effects of silicon on plant diseases. The chapters address the dynamics of silicon in soils and plants; the history of silicon in the control of plant diseases; the use of silicon to control soil-borne, seed-borne and foliar diseases in monocots and dicots; the mechanisms involved in the host resistance against infection by plant pathogens mediated by silicon as well as the current knowledge at the omics level, and finally, highlights and prospects for using silicon in the future.
