Book excerpt: Este trabalho analisa a eficiencia economica, intrafazenda, na producao de cana-de-acucar de acordo com a teoria economica da producao estimando funcoes de producao tipo Cobb-Douglas. Utiliza-se de dados dos modulos de producao (talhoes) coletados pelo controle operacional agricola, referentes a safra 86/87. As funcoes de producao ajustadas apresentam variavel dependente a producao de cana e como variaveis dependentes: terra, nitrogenio, fosforo, potassio, vinhaca herbicidas. Os resultados obtidos mostram que o modelo Cobb-Douglas ajustou-se adequadamente aos dados amostrados dos modulos de producao e que apresentou retornos constantes a escala. A analise da relacao entre o Valor da Produtividade Fisica Marginal dos recursos e os respectivos precos mostram ...que os mesmos nao foram alocados eficientemente na safra considerada. Para se atingir o intervalo de otimo economico na alocacao dos recursos, a empresa em estudo deveria implementar as seguintes recomendacoes: aumentar o nivel de utilizacao dos recursos terra, potassio e vinhaca; reduzir o nivel de utilizacao dos recursos nitrogeneo, herbicidas e fosforo. Concluio-se que o ajustamento de funcoes de producao utilizando dados dos modulos de producao e exequivel e apresenta resultados uteis na tomada de decisoes ao nivel da empresa (intrafazenda).

Book Synopsis Strategies and Tools for a Sustainable Rural Rio de Janeiro by : Udo Nehren
Download or read book Strategies and Tools for a Sustainable Rural Rio de Janeiro written by Udo Nehren and published by Springer. This book was released on 2018-08-16 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of recent developments in land, ecosystem, and water management in the Brazilian state of Rio de Janeiro. The state is located in the biodiversity hotspot of the Atlantic Forest (Mata Atlântica), a biome characterized by high biological diversity and endemism. At the same time the state of Rio de Janeiro emerged to one of the economic hubs in Latin America. This development process has been accompanied by population growth, industrialization, urbanization, as well as consumption and degradation of land and water resources. In the past years many efforts have been made to stop or at least slow down these degradation processes and restore degraded environments with the overall goal to bring together sustainable management of natural resources, nature conservation, and economic development. An overview is provided of the different strategies and tools that have been developed in the fields of agriculture, ecosystem management and biodiversity, integrated water management, land restoration, disaster risk reduction and climate change adaptation, as well as environmental governance and economic instruments. This book covers a wide spectrum from applied research to science‐policy interfaces, planning concepts, and technical tools and has a model character for other rural areas in Latin America. Target groups are scientists, practitioners, policy makers and graduate students in the field of environmental management. The different chapters are written by researchers and practitioners of the German‐Brazilian project INTECRAL (Integrated Eco Technologies and Services for a Sustainable Rural Rio de Janeiro), the rural development program Rio Rural under the state secretary for agriculture and animal husbandry, as well as invited scientists from Brazilian universities and research institutes. It bridges existing gaps between science, policies, and practice in rural development.

Book Synopsis Production of Ethanol from Sugarcane in Brazil by : Márcia Azanha Ferraz Dias de Moraes
Download or read book Production of Ethanol from Sugarcane in Brazil written by Márcia Azanha Ferraz Dias de Moraes and published by Springer Science & Business Media. This book was released on 2014-03-31 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of Brazil in the large-scale production and use of fuel ethanol has been widely discussed and analyzed by other countries interested in adopting policies designed to encourage the use of biofuels. Within this context, certain questions arise: Could the Brazilian experience be replicated in other countries? What were the conditions that enabled the creation of the Brazilian Proálcool (National Ethanol Program and what lessons can be learned? To examine these issues, it is important to understand the functioning of the key, interconnected markets (those for sugarcane, sugar and ethanol), which, from their inception, were the objects of extensive government intervention until 1999. Two main conditions enabled the creation of Proálcool: robust production of sugarcane and sugar (tightly regulated by the government, which applied the numerous regulations then in place); and the military regime that was in place at the time, whose decision-making and enforcement powers were quite broad, facilitating the carrying out of the necessary actions, as well as making it easier to coordinate the activities of the various stakeholders and sectors involved. This book increases understanding of the functioning of the sugarcane supply chain in Brazil, not only during the phase of government intervention but also in recent years (in the free-market environment). The lessons, positive and negative, gleaned from the Brazilian experience can contribute to reflection on and the development of alternative modalities of biofuel production in other countries, making the book of interest to scholars and policy-makers concerned with biofuel and renewable resources as well as economic development.

Download or read book Crop Science written by Roxana Savin and published by Springer. This book was released on 2019-04-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive and state-of-the-art source reference for understanding the functions and mechanisms responsible for yield and quality determination under a range of conditions. By uncovering relationships and challenges of successful and scalable crop management and breeding, this volume addresses the challenges of environmentally sound production of bulk and quality food, fodder, fiber, and energy which are of ongoing international concern. Contemporary agriculture and crop management confronts the challenge of increasing demand in terms of quantitative and qualitative production targets. These targets have to be achieved against a background of climate change, including soil and water scarcity and higher temperatures, and the environmental and social aspects of agricultural sustainability. This book views crop production as an active source of methods, theories, ideas, and tools for application in genetic improvement and agronomy.
Book Synopsis Sugarcane Biofuels by : Muhammad Tahir Khan
Download or read book Sugarcane Biofuels written by Muhammad Tahir Khan and published by Springer. This book was released on 2019-06-29 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sugarcane exhibits all the major characteristics of a promising bioenergy crop including high biomass yield, C4 photosynthetic system, perennial nature, and ratooning ability. Being the largest agricultural commodity of the world with respect to total production, sugarcane biomass is abundantly available. Brazil has already become a sugarcane biofuels centered economy while Thailand, Colombia, and South Africa are also significantly exploiting this energy source. Other major cane producers include India, China, Pakistan, Mexico, Australia, Indonesia, and the United States. It has been projected that sugarcane biofuels will be playing extremely important role in world’s energy matrix in recent future. This book analyzes the significance, applications, achievements, and future avenues of biofuels and bioenergy production from sugarcane, in top cane growing countries around the globe. Moreover, we also evaluate the barriers and areas of improvement for targeting efficient, sustainable, and cost-effective biofuels from sugarcane to meet the world’s energy needs and combat the climate change.
Book Synopsis Advances in Fungal Biotechnology for Industry, Agriculture, and Medicine by : Jan S. Tkacz

This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past half century, filamentous fungi have grown in commercial importance not only in the food industry but also as sources of pharmaceutical agents for the treatment of infectious and metabolic diseases and of specialty proteins and enzymes used to process foods, fortify detergents, and perform biotransformations. The commercial impact of molds is also measured on a negative scale since some of these organisms are significant as pathogens of crop plants, agents of food spoilage, and sources of toxic and carcinogenic compounds. Recent advances in the molecular genetics of filamentous fungi are finding increased application in the pharmaceutical, agricultural, and enzyme industries, and this trend promises to continue as the genomics of fungi is explored and new techniques to speed genetic manipulation become available. This volume focuses on the filamentous fungi and highlights the advances of the past decade, both in methodology and in the understanding of genomic organization and regulation of gene and pathway expression.

Book Synopsis Introduction to Biometrical Genetics by : Kenneth Mather
Download or read book Introduction to Biometrical Genetics written by Kenneth Mather and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the second edition of Biometricai Genetics, which appeared in 1971, we set out to give a general account of the subject as it had developed up to that time. Such an account necessarily had to be comprehensive and reasonably detailed. Although it could be, and indeed has been, used by those who were making an acquaintance with this branch of genetics for the first time, it went beyond their needs. We have been encouraged therefore to write an introduction to the genetical analysis of continuous variation aimed primarily at senior undergraduate and postgraduate students, and concentrating on basic considerations, basic principles and basic techniques. This has meant, of course, omitting all reference to some phenomena of more restricted interest, notably sex-linkage, ma ternal effects, haploidy and polyploidy. It has meant, too, that even with some phenomena which have been included, like interactions, linkage and effective factors, the discussions cannot go into full detail. Anyone who is interested, however, can find further information in Biometricai Genetics, to which detailed references have been given where it ap peared that these would be helpful. The order of presentation has been changed with the aim of making it easier for beginners.
