A. da SILVA and published by . This book was released on 1994 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Com o objetivo de avaliar o comportamento de diferentes métodos de preparo do solo e doses de fertilizante NPK para o feijão da seca na região Sul de Minas Gerais, foi conduzido um estudo pioneiro em propriedades particulares nos municípios de Perdões e Lavras. Em Perdões, onde a área havia sido anteriormente utilizada para produção de silagem de milho, empregou-se a cultivar Carioca-MG e a cultura não foi irrigada. Em Lavras o plantio anterior foi milho para grãos e a cultivar utilizada foi Carioca, conduzindo-se o ensaio sob pivô-central. O delineamento experimental em ambas as localidades foi o de blocos casualizados em esquema de parcelas subdivididas com duas repetições.

Available in PDF, EPUB and Kindle. Book excerpt: O objetivo deste trabalho foi identificar os efeitos de sistemas de preparo do solo e de rotações de culturas sobre o rendimento de grãos e economicidade da cultura do feijoeiro (Phaseolus vulgaris L.) irrigado pelo sistema pivô central. O trabalho foi conduzido durante seis anos consecutivos no Centro Nacional de Pesquisa de Arroz e Feijão (CNPAF), localizado no município de Santo Antônio de Goiás (GO), em Latossolo Vermelho-Escuro, de textura argilosa. O experimento consistiu de um fatorial 4x6, em delineamento inteiramente casualizado com parcelas subdivididas. Os sistemas de preparo do solo foram: P1 - arado de aiveca (novembro-dezembro) alternado com grade aradora (maio-junho), P2 - arado de aiveca contínuo, P3 - grade aradora contínua, e P4 - plantio direto, e as rotações de culturas: R1 - arroz-feijão, R2 - milho-feijão, R3 - soja-trigo, R4 - soja-trigo-soja-feijão-arroz-feijão, R5 - arroz consorciado com calopogônio-feijão e R6 - milho-feijão-milho-feijão-arrozfeijão. As rotações R1, R2, R3 e R5 foram anuais e as R4 e R6, trienais. Neste trabalho analisaram-se somente as rotações que continham feijão. O arroz, o milho e a soja foram semeados em novembro-dezembro (verão) e o feijão e o trigo em maio-junho (inverno). Houve efeito do preparo do solo e das rotações de cultura sobre o rendimento de grãos do feijoeiro. A cultura produziu mais quando se utilizou no preparo do solo a combinação de arado de aiveca, nos plantios de verão, e grade aradora nos de inverno. Os rendimentos do feijoeiro foram maiores quando a cultura foi implantada bienalmente na mesma área, nas rotações com arroz/calopogônio e arroz, e menores nas rotações com milho. O feijoeiro irrigado, com relação ao preparo do solo e rotações de culturas foi economicamente viável, propiciando taxas de retorno que variaram de 67% a 97%.

Download or read book Common Bean Improvement in the Twenty-First Century written by S.P. Singh and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common bean (Phaseolus vulgaris L. ) is the most important pulse crop in the world. It is an important source of calories, proteins, dietary fibers, minerals, and vitamins for millions of people in both developing and developed countries worldwide. It complements cereals and other carbohydrate-rich foods in providing near-perfect nutrition to people of all ages. Moreover, a regular intake ofbeans helps lower cholesterol and cancer risks. Despite the fact that per capita consumption of common bean in some developed countries (e. g. , the U. S. A. ) has been increasing over the last several years, in general, the average global per capita consumption is declining because production is unable to keep up with the population growth. Moreover, increasing demand for pesticide-free food products, concern for natural resources conservation, and the need to reduce production costs offer daunting challenges to the twenty-first century policy makers, bean growers, and researchers alike. High yielding, high quality bean cultivars that require less water, fertilizers, pesticides, and manual labor combined with integrated management of abiotic and biotic stresses will have to be developed. Eminent bean researchers were invited to contemplate these issues, prepare a state-of-the-art account on most relevant topics, and offer their insight into research directions into the twenty-first century. Four excellent books have been published covering various aspects ofthe common bean since 1980. These books are: I) Bean Production Problems nd in the Tropics (l SI ed. 1980, 2 ed. 1989), H. F. Schwartz & M. A.

Download or read book Presidents and Terminal Logic Behavior written by Genevieve M. Kehoe and published by Texas A&M University Press. This book was released on 2014-05-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presidents of nations with constitutionally imposed term limits are often viewed as growing weaker as they approach the end of their time in office. However, in this important new study, political scientist Genevieve M. Kehoe argues that because such chief executives are free from reelection constraint and often still enthusiastic to create a legacy by pursuing bold projects, they may accomplish significant initiatives. Kehoe has developed a concept for this which she calls “Terminal Logic Behavior” (TLB). Presidents and Terminal Logic Behavior: Term Limits and Executive Action in the United States, Brazil, and Argentina provides both case studies and quantitative evidence to show how US presidents of the last three decades have utilized decrees on foreign, domestic, and environment policy during their final months in office. She finds a systematic pattern of decree use consistent with the mark of TLB in a most unexpected place—presidents’ use of national emergency powers. In a careful comparative analysis, she also finds support for her argument in the Argentinean and Brazilian experience of the same period.

Download or read book Proximal Soil Sensing written by Raphael A. Viscarra Rossel and published by Springer Science & Business Media. This book was released on 2010-07-25 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on developments in Proximal Soil Sensing (PSS) and high resolution digital soil mapping. PSS has become a multidisciplinary area of study that aims to develop field-based techniques for collecting information on the soil from close by, or within, the soil. Amongst others, PSS involves the use of optical, geophysical, electrochemical, mathematical and statistical methods. This volume, suitable for undergraduate course material and postgraduate research, brings together ideas and examples from those developing and using proximal sensors and high resolution digital soil maps for applications such as precision agriculture, soil contamination, archaeology, peri-urban design and high land-value applications, where there is a particular need for high spatial resolution information. The book in particular covers soil sensor sampling, proximal soil sensor development and use, sensor calibrations, prediction methods for large data sets, applications of proximal soil sensing, and high-resolution digital soil mapping. Key themes: soil sensor sampling – soil sensor calibrations – spatial prediction methods – reflectance spectroscopy – electromagnetic induction and electrical resistivity – radar and gamma radiometrics – multi-sensor platforms – high resolution digital soil mapping - applications Raphael A.
