This book was released on 2000 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foram conduzidos dois experimentos entre junho e novembro de 1999, a campo e no Laboratório de Pós-Colheita do Núcleo Experimental de Ciências Agrárias - NCA, da Universidade Federal de Mato Grosso do Sul - UFMS, com o objetivo de avaliar os efeitos de diferentes lâminas de irrigação e doses de fósforo sobre a produção de raízes de plantas da cenoura 'Brasília', em condições ambientes. Os fatores estudados foram seis lâminas de irrigação (218,87; 265,77; 312,67; 359;57; 406,47 e 453,37 mm), correspondentes a 70, 85, 100, 115, 130 e 145% da evaporação de água obtidos com o Minievaporímetro-UFMS (MEv-UFMS), e cinco doses de fósforo (0; 200; 400; 600; e 800 kg ha-1 de P2O5). Os fatores em estudo foram arranjados em fatorial 5 (doses de P2O5) x 6 (lâminas de irrigação). A cenoura foi semeada de forma direta e a colheita foi realizada aos 85 dias após a emergência, quando foram avaliadas as produções de massa fresca da parte aérea e de raízes pequenas, médias, grandes e refugo, e a classificação de raízes comercializáveis e não comercializáveis, e a produção de massa seca de parte aérea e raízes. Considerando os mesmos tratamentos, doses de fósforo e lâmina de água, estudados no experimento de campo, avaliaram-se as perdas de massa das raízes de cenoura no laboratório de pós colheita. As unidades experimentais formadas de seis raízes de tamanho médio, foram dispostas no delineamento experimental inteiramente casualizado, com três repetições. Diariamente, até quatro dias após a colheita, foram feitas as pesagens individuais das raízes para determinar a perda de massa durante o período de armazenamento. O fator lâmina e a interação lâmina e doses de fósforo não influenciaram significativamente nas produções de matéria fresca e seca, exceto para a produção de matéria fresca da parte aérea, que foi crescente com o aumento das lâminas de irrigação e das doses de fósforo utilizadas. As doses de fósforo propiciaram aumentos de produção de raízes grandes (630,36 kg ha-1 de P2O5, obtendo-se 1440,62 g parcela-1). As produções de massa fresca de raízes classificadas como refugos e raízes totais produzidas, foram crescentes com o aumento das doses de fósforo utilizadas, não atingindo o ponto de máxima produção. No terceiro dia de armazenamento em condições ambientais, a dose de fósforo (601,06 kg ha-1 de P2O5) proporcionou menores perda de massa de cenouras.

Download or read book Analise economica da producao de cenoura (Daucus carota L.) irrigada written by J. de A. CARVALHO and published by . This book was released on 1995 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dentre as umbeliferas, a cenoura e a hortalica de maior importancia economica. Como as informacoes a respeito da irrigacao dessa cultura sao escassas, torna-se necessario o desenvolvimento de pesquisas sobre o assunto conduzida sobre diferentes laminas de irrigacao, considerando tambem o aspecto economico. Este trabalho teve como objetivo determinar o efeito da lamina de agua sobre a produtividade fisica e economic da cultura da cenoura. Conduziu-se um experimento no delineamento inteiramente casualisado, com cinco tratamentos (laminas de irrigacao correspondentes a 0,6, 0.8, 1,0, 1,2 e 1,4 vezes a evapotranspiracao potencial da cultura ETpc) e cinco repeticoes. A maior produtividade comercial foi 36 t/ha alcancada com a aplicacao de uma lamina de 443 mm. A lamina de irrigacao de maior retorno economico foi 438 mm, correspondendo a uma produtividade de 35,9 t/ha. Os custos variaveis da irrigacao tiveram pouca influencia sobre a determinacao da lamina de maior retorno economico devido aos altos custos de implantacao do sistema de producao dessa cultura.
Book Synopsis Agricultural Innovation Systems by : World Bank
Download or read book Agricultural Innovation Systems written by World Bank and published by World Bank Publications. This book was released on 2012-02-21 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: Managing the ability of agriculture to meet rising global demand and to respond to the changes and opportunities will require good policy, sustained investments, and innovation - not business as usual. Investments in public Research and Development, extension, education, and their links with one another have elicited high returns and pro-poor growth, but these investments alone will not elicit innovation at the pace or on the scale required by the intensifying and proliferating challenges confronting agriculture. Experience indicates that aside from a strong capacity in Research and Development, the ability to innovate is often related to collective action, coordination, the exchange of knowledge among diverse actors, the incentives and resources available to form partnerships and develop businesses, and conditions that make it possible for farmers or entrepreneurs to use the innovations. While consensus is developing about what is meant by 'innovation' and 'innovation system', no detailed blueprint exists for making agricultural innovation happen at a given time, in a given place, for a given result. The AIS approach that looks at these multiple conditions and relationships that promote innovation in agriculture, has however moved from a concept to a sub-discipline with principles of analysis and action. AIS investments must be specific to the context, responding to the stage of development in a particular country and agricultural sector, especially the AIS. This sourcebook contributes to identifying, designing, and implementing the investments, approaches, and complementary interventions that appear most likely to strengthen AIS and to promote agricultural innovation and equitable growth. It emphasizes the lessons learned, benefits and impacts, implementation issues, and prospects for replicating or expanding successful practices. The information in this sourcebook derives from approaches that have been tested at different scales in different contexts. It reflects the experiences and evolving understanding of numerous individuals and organizations concerned with agricultural innovation, including the World Bank. This information is targeted to the key operational staff in international and regional development agencies and national governments who design and implement lending projects and to the practitioners who design thematic programs and technical assistance packages. The sourcebook can also be an important resource for the research community and nongovernmental organizations (NGOs).

Book Synopsis Developing Biodynamic Agriculture by : Adalbert Graf von Keyserlingk
Download or read book Developing Biodynamic Agriculture written by Adalbert Graf von Keyserlingk and published by Temple Lodge Publishing. This book was released on 1999 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic manipulation, industrial agriculture, and disregard for natural laws have all led to growing public concern over the safety of the food on our tables. As a result, there is a growing interest in organic methods of farming. Biodynamic agriculture (the method developed by Rudolf Steiner) is an extension of the organic approach that uses special preparations that enrich the soil and enliven our food by working in harmony with cosmic and earthly forces. Biodynamic agriculture was launched by Steiner at a conference on the Koberwitz estate in Germany. Adalbert Count Keyserlingk, the son of the hosts, was present, and this book reflects his lifelong absorption in biodynamic methods. It presents a wide range of material, including the count's personal experiences of Steiner at work, his reflections on practical research and experimentation (including photographic documentation), and descriptions of biodynamic preparations. More than anything else, his words successfully convey the enthusiasm, the exalted feelings, and the power of initiative that arose from Rudolf Steiner's work in this field--to develop a method of farming that provides nutritious, safe food for the future.
Book Synopsis Commentary on Dr. Rudolf Steiner's Agriculture Course by : Enzo Nastati
Download or read book Commentary on Dr. Rudolf Steiner's Agriculture Course written by Enzo Nastati and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1924 Dr Rudolf Steiner gave 8 lectures which have since become known as the 'Agriculture Course'. To many this course was the seed which grew into modern organic agriculture, and certainly into biodynamic agriculture. However, even for those familiar with Dr Steiner's wider work - Anthroposophy - these lectures are very challenging to comprehend and build upon. This commentary by Enzo Nastati shows both a thorough penetration of the subject and offers insight to the developments that Enzo Nastati and his team have built upon Dr Steiner's foundation. In 30 meetings from 2001 to 2005 this was explained to the farmers and gardeners who wished to develop Dr Steiner's work. The revised transcripts have now been translated in English, and promise to assist sincere students of biodynamic agriculture to become more conscious of what Dr Steiner offered 80 years previously.
