Download or read book Guide to Participatory Varietal Selection for Submergence tolerant Rice written by T. R. Paris and published by IRRI. This book was released on 2011 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Green Revolution averted the threat of famine through the rapid adoption of improved rice varieties. However, despite this huge success, hundreds of millions of poor rice-farming families in rainfed areas still live in poverty and suffer from food (rice) insecurity. Despite many released improved rice varieties for rainfed conditions, farmers still use local varieties that can withstand drought and floods but have low yields or they use the same varieties for many years because of a lack of better varieties. Rainfed rice farmers are slow to adopt improved varieties because of several problems. One problem is more of extension than breeding - many farmers, particularly those living in remote rainfed areas, may not have access to or information about the seed of new varieties. Another problem is that variety testing programs are often conducted on-station, which does not represent farmers' fields. Moreover, conventional rice breeding programs usually seek farmers' input only at the very end of the process, when newly released varieties, usually one or two per year, are evaluated in on-farm demonstration trials. Often, in remote and unfavorable areas, subsistence farmers, who comprise the majority of the rural farming population in Asia, give importance to social and cultural dimensions aside from the agronomic performance of the new rice varieties. The complexities of developing acceptable varieties for variable and stressful rainfed environments require that breeders become deeply familiar with men and women farmers' needs and preferences. Since 1977, IRRI has been making efforts to improve communication among farmers, breeders, and extension workers so that men and women farmers' concerns and preferences are considered in plant breeding objectives. Participatory varietal selection (PVS) is a simple way for breeders and agronomists to learn which varieties perform well on-station and on-farm and to obtain feedback from the potential end users in the early phases of the breeding cycle. It is a means for social scientists to identify the varieties that most men and women farmers prefer, including the reasons for their preference and constraints to adoption. Based on IRRI's experience in collaboration with national agricultural research and extension system partners and farmers, PVS, which includes "researcher-managed" and "farmer-managed" trials, is an effective strategy for accelerating the dissemination of stress-tolerant varieties. PVS has also been instrumental in the fast release of stress-tolerant varieties through the formal varietal release system. This guide on PVS will complement the various training programs given by IRRI for plant breeders, agronomists, and extension workers engaged in rice varietal development and dissemination.
Download or read book Statistical Procedures for Agricultural Research written by Kwanchai A. Gomez and published by John Wiley & Sons. This book was released on 1984-02-17 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here in one easy-to-understand volume are the statistical procedures and techniques the agricultural researcher needs to know in order to design, implement, analyze, and interpret the results of most experiments with crops. Designed specifically for the non-statistician, this valuable guide focuses on the practical problems of the field researcher. Throughout, it emphasizes the use of statistics as a tool of research—one that will help pinpoint research problems and select remedial measures. Whenever possible, mathematical formulations and statistical jargon are avoided. Originally published by the International Rice Research Institute, this widely respected guide has been totally updated and much expanded in this Second Edition. It now features new chapters on the analysis of multi-observation data and experiments conducted over time and space. Also included is a chapter on experiments in farmers' fields, a subject of major concern in developing countries where agricultural research is commonly conducted outside experiment stations. Statistical Procedures for Agricultural Research, Second Edition will prove equally useful to students and professional researchers in all agricultural and biological disciplines. A wealth of examples of actual experiments help readers to choose the statistical method best suited for their needs, and enable even the most complicated procedures to be easily understood and directly applied.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation of plant resources is often focused on seed banks and botanical gardens. However, the two authors of this volume present a comprehensive conservation strategy that complements this ex-situ approach with practical guidance on in-situ management and conservation of plant resources. The book aims to facilitate better management of protected areas and to illustrate new approaches to conservation of plants within their landscapes. It draws on concepts from forestry, the agricultural sciences, anthropology, ethnology and ethnobotany and should be useful to practitioners, academics and policy-makers.

Download or read book Farmers Crop Varieties and Farmers Rights written by Michael Halewood and published by Routledge. This book was released on 2016-03-10 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop plant varieties developed by local farmers, commonly referred to as ‘farmers' varieties’, are problematic because there are no fixed taxonomic or legal definitions of them. As a result, policies to increase the share of benefits farmers receive from the use of such varieties struggle to have an effect. Aiming to clarifying these issues, this volume explores the nature of farmers’ varieties in the context of their biological, social and legal significance. The book addresses the complexities of defining what farmers’ varieties are and how they differ from one another and from generic varieties. It then charts the evolution of the concept of ‘farmers’ rights’, from the dawn of ‘genetic resources’ as a subject worthy of international attention, to the first legal recognition of the concept, through to current efforts to develop national level policies and laws. Further, the book examines outstanding policy-making challenges linked to the absence of fixed taxonomic or legal definitions of farmers’ varieties. Case studies are included from Africa, Asia, Europe and South America in which farmers, researchers and policy advocates have been confronted with the issues raised in this book. Various solutions are considered based on revised or new definitions of farmers’ varieties that reflect the biological and cultural realities in which they are produced, and the relative costs and benefits of attempting to implement each of the policies discussed.
