Download or read book Management of Biological Nitrogen Fixation for the Development of More Productive and Sustainable Agricultural Systems written by J.K. Ladha and published by Int. Rice Res. Inst.. This book was released on 1995-09-30 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reprinted from Plant and Soil, v.174, nos.1-2 (1995), this volume is devoted to discussions on the role of biological nitrogen fixation (BNF) in agricultural sustainability. Papers presented on BNF in crop forage and tree legumes are augmented with discussion of integrated farming systems involving BNF, soil and N management, and recycling of legume residues. BNF by non-legumes is discussed and attempts to transform cereals into nodulating plants are critically reviewed. Also described are advances in the development of new methodologies to understand symbiotic interactions and to assess N-2 fixation in the field; means of enhancing BNF through plant and soil management; breeding and selection; problems encountered in exploiting BNF under farmers' field conditions; and promising approaches to improve BNF exploitation.

Download or read book World Development Report 1994 written by and published by World Bank Publications. This book was released on 1994 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: World Development Report 1994 examines the link between infrastructure and development and explores ways in which developing countries can improve both the provision and the quality of infrastructure services. In recent decades, developing countries have made substantial investments in infrastructure, achieving dramatic gains for households and producers by expanding their access to services such as safe water, sanitation, electric power, telecommunications, and transport. Even more infrastructure investment and expansion are needed in order to extend the reach of services - especially to people living in rural areas and to the poor. But as this report shows, the quantity of investment cannot be the exclusive focus of policy. Improving the quality of infrastructure service also is vital. Both quantity and quality improvements are essential to modernize and diversify production, help countries compete internationally, and accommodate rapid urbanization. The report identifies the basic cause of poor past performance as inadequate institutional incentives for improving the provision of infrastructure. To promote more efficient and responsive service delivery, incentives need to be changed through commercial management, competition, and user involvement. Several trends are helping to improve the performance of infrastructure. First, innovation in technology and in the regulatory management of markets makes more diversity possible in the supply of services. Second, an evaluation of the role of government is leading to a shift from direct government provision of services to increasing private sector provision and recent experience in many countries with public-private partnerships is highlighting new ways to increase efficiency and expand services. Third, increased concern about social and environmental sustainability has heightened public interest in infrastructure design and performance.

Available in PDF, EPUB and Kindle. Book excerpt: Written by historians and scientists from all over the world as well as by former and active staff members, this publication gives an inside perspective on the role played by UNESCO in the history of international scienctific co-operation over the past six decades. It is divided into six sections under the headings of: setting the scene, 1945-1965; basic sciences and engineering; environmental sciences; science and society; overviews and analyses; and looking ahead. It also features a list of chronological milestones during this 60-year period.
Download or read book Improving Soil Fertility Recommendations in Africa using the Decision Support System for Agrotechnology Transfer DSSAT written by Job Kihara and published by Springer Science & Business Media. This book was released on 2012-03-12 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book gives a detailed description of the application of DSSAT in simulating crop and soil processes within various Agro-ecological zones in Africa. The book, an output of a series of 3 workshops, provides examples of the application of DSSAT models to simulate nitrogen applications, soil and water conservation practices including effects of zai technology, phosphorus and maize productivity, generation of genetic coefficients, long-term soil fertility management technologies in the drylands, microdosing, optimization of nitrogen x germplasms x water, spatial analysis of water and nutrient use efficiencies and, tradeoff analysis. The minimum dataset requirements for DSSAT is discussed. This book arises from attempts to address the limited use of models in decision support by African agricultural (both soil scientist and agronomists) scientists.
