This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, we examine whether the adoption of late blight resistant cultivars has an effect on yields and fungicide use. We will focus on the Amarilis variety which is considered more resistant to late blight than other varieties adopted by the farmers in the sample. Using data from three main potato producer states in the Peruvian Andes, significant positive effects on yields and negative effects on fungicide use are found. Specifically, the damage abatement approach provides evidence that Amarilis adoption enhances output maximization mainly through the control of late blight. At the discount rate of 10%, the probable net present value (NPV) of the net benefits accruing to farmers through the adoption of Amarilis amounts to almost 9 million dollars.

Download or read book Agrobiodiversity written by Karl S. Zimmerer and published by MIT Press. This book was released on 2023-10-31 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experts discuss the challenges faced in agrobiodiversity and conservation, integrating disciplines that range from plant and biological sciences to economics and political science. Wide-ranging environmental phenomena—including climate change, extreme weather events, and soil and water availability—combine with such socioeconomic factors as food policies, dietary preferences, and market forces to affect agriculture and food production systems on local, national, and global scales. The increasing simplification of food systems, the continuing decline of plant species, and the ongoing spread of pests and disease threaten biodiversity in agriculture as well as the sustainability of food resources. Complicating the situation further, the multiple systems involved—cultural, economic, environmental, institutional, and technological—are driven by human decision making, which is inevitably informed by diverse knowledge systems. The interactions and linkages that emerge necessitate an integrated assessment if we are to make progress toward sustainable agriculture and food systems. This volume in the Strüngmann Forum Reports series offers insights into the challenges faced in agrobiodiversity and sustainability and proposes an integrative framework to guide future research, scholarship, policy, and practice. The contributors offer perspectives from a range of disciplines, including plant and biological sciences, food systems and nutrition, ecology, economics, plant and animal breeding, anthropology, political science, geography, law, and sociology. Topics covered include evolutionary ecology, food and human health, the governance of agrobiodiversity, and the interactions between agrobiodiversity and climate and demographic change.
Download or read book Potato and Sweetpotato in Africa written by Jan Low and published by CABI. This book was released on 2015-10-28 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweetpotato and potato are expanding faster than any other food crops in sub-Saharan Africa. There is growing investment in research to address bottlenecks in value chains concerning these two crops, and growing interest from the private sector in investing in them. This book addresses five major themes on sweetpotato and potato: policies for germplasm exchange, food security and trade in Africa; seed systems; breeding and disease management; post-harvest management, processing technologies and marketing systems; nutritional value and changing behaviours.

Book excerpt: This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.
Download or read book New Light on a Hidden Treasure written by Food and Agriculture Organization of the United Nations and published by Fao. This book was released on 2009 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Year of the Potato (IYP) in 2008 was a celebration of one of humanity's most important and universally loved staple foods. This end-of-year review records IYP's achievements and underscores its essential message: that the potato is a vital part of the global food system, and will play an ever greater role in strengthening world food security and alleviating poverty. This book seeks to contribute to strengthening the potato industry everywhere. It will be of particular value to developing countries that recognize the potential of the potato to drive economic development and sustain rural livelihoods. Also published in Arabic, Chinese, French, Russian and Spanish.

Book excerpt: In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.

Download or read book Solanum tuberosum written by Mustafa Yildiz and published by BoD – Books on Demand. This book was released on 2021-12-22 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato (Solanum tuberosum L.) is the fourth-largest food crop produced in the world with approximately 370 million tonnes. This product is a staple in many diets throughout the world and the underground swollen tubers of the plant are rich sources of proteins, carbohydrates, minerals (K, Mn, Mg, Fe, Cu and P), and vitamins (C, B1, B3, B6, K, folate, pantothenic acid). Improvement of new potato cultivars resistant to biotic and abiotic factors is extremely important, as these are the main reasons for decreased potato production. Seed tuber production and tuber storage under healthy conditions after harvest are two important issues in potato cultivation. As such, this book discusses the importance of the potato plant and examines ways to increase its production and develop new cultivars resistant to stress factors via conventional and biotechnological methods.
