Available in PDF, EPUB and Kindle. Book excerpt: Plant breeders continue to make significant advances in developing high yield ing, adaptable, disease-free crops. These advances, however, are not realized until an efficient seed production system is in place that rapidly increases geneti cally superior crops and makes them available to the consumer in large quantities at a reasonable cost. Successful seed production requires seed to be genetically pure, free of admixtures, and able to establish rapidly a uniform stand. Seed production is a complex process. Rigorous production criteria are followed by both seed producer and seed companies to ensure that high-quality seed is produced and marketed. These criteria become even more stringent in hybrid seed production. This volume identifies the factors most critical in a successful seed production operation. The fundamental considerations common to all seed crops are established in Part I, Principles of Seed Production. From this founda tion, the practices of seed production are provided in detail in Part II, Seed Production of Specific Crops.

This book was released on 2012-12-06 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Fourth Edition of Principles of Seed Science and Technology, like the fIrst three editions, is written for the advanced undergraduate student or lay person who desires an introduction to the science and technology of seeds. The fIrst nine chapters present the seed as a biological system and cover its origin, development, composition, function (and sometimes nonfunction), performance and ultimate deterioration. The last nine chapters present the fundamentals of how seeds are produced, conditioned, evaluated and distributed in our modern agricultural society. Two new chapters have been added in this fourth edition, one on seed ecology and the second on seed drying. Finally, revisions have been made throughout to reflect changes that have occurred in the seed industry since publication of the Third Edition. Because of the fundamental importance of seeds to both agriculture and to all of society, we have taken great care to present the science and technology of seeds with the respect and feeling this study deserves. We hope that this feeling will be communicated to our readers. Furthermore, we have attempted to present information in a straight-forward, easy-ta-read manner that will be easily understood by students and lay persons alike. Special care has been taken to address both current state-of-the-art as well as future trends in seed technology.

Download or read book Seeds Toolkit Module 6 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-10-18 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seeds are the vehicle for delivering the improvements in a crop to the farmer’s field. They are therefore a critical input in agricultural production. Seeds are also unique in that they must remain alive and healthy when they are used and that they are also the input that farmers can produce by themselves. It is estimated that 25–33% of the world grain crop, including seeds, is lost each year during storage. To avert this obvious drawback to food security and nutrition, this module provides the underlying principles for effective seed storage and the associated practices. The module provides guidance on the preservation of seeds under controlled environmental conditions so as to maximize seed viability for the long periods that may be required from harvesting through processing to planting.

Available in PDF, EPUB and Kindle. Book excerpt: This publication provides an approach by which conservationists can determine whether or not long-term seed storage is feasible for a particular species, i.e. whether or not that species shows orthodox seed storage behaviour, and provides advice on the implementation of the protocol, examples of ways in which the results from seed storage studies could be misinterpreted due to confounding factors, as well as several alternative approaches for estimating seed storage behaviour prior to carryng out actual investigations with the seeds. In particular, the latter section introduces the concept of a multicriteria approach for estimating seed storage behaviour.

Available in PDF, EPUB and Kindle. Book excerpt: The readers will get knowledge about seeds, science and technology involved in this subject. Seeds are fertilised mature ovules shaped through sexual reproduction in plants. It is the cheapest and key input in agriculture. It is estimated that good quality seeds of improved varieties can contribute about 20-25% increase in yield. Seed technology is an interdisciplinary science, involves such activities as variety development, evaluation and release seed development, seed processing, seed storage, seed testing, seed certification, seed quality control and seed marketing etc., through which the genetic and physical characteristic of seeds could be improved. Each topic was discussed in separate chapter and this book will prove extremely useful to its readers.

Available in PDF, EPUB and Kindle. Book excerpt: Seed is the source of future plants or foods, is the storage place of culture of history, is the first link in the food chain, is the ultimate symbol of food security. Seed is the source of life. Seeds are basic in crop production. No agricultural practice can improve a crop beyond the limits set by the seed. Quality seed is the key for successful agriculture, which demands each and every seed should be readily germinable and produce a vigorous seedling ensuring high yield. “Care with the seed and joy with the harvest” and “Good seed doesn’t cost it always pays” are the popular adage which enlightens the importance of the quality seed. The farmers always very much interested in the best seed management practices which are safe, environmentally sound and scientifically proven technologies. Understandably, in view of the importance of quality seeds in Agriculture, both as a product and as a means of establishing a crop, most attention at all levels of investigation has been directed to crop seeds. Since seed is a biological entity, deterioration beyond harvest is inevitable. The consequences of low quality seeds are poor germination, low and delayed emergence and weak growth leading to poor field stand and ultimately reflecting on reduced yield. Low productivity could be attributed broadly to use of poor quality seeds. At present to overcome this, several seed enhancement techniques are available for quality upgradation. It has two goals; one is related to seed designing and other to seed functioning. The rationale for pre-sowing seed enhancement techniques is to mobilize the seeds own resources and to augment them with external resources to get maximum improvement in field stand establishment and yield. To achieve this, several physical, physiological and biochemical treatments are available at present to give value addition to seeds. Physiological seed treatments that improve seed performance are based primarily on seed hydration and dehydration. Among several non physiological seed treatments, coating or pelleting can also indirectly improve seed germination, stand establishment and crop productivity.

Available in PDF, EPUB and Kindle. Book excerpt: From prehistoric times man has had a pecial s relationship with seed plants - as a source of food, materials for tools, buildings, clothing and pharmaceuticals, and for ornamenting his surroundings for his own delight (probably in that chronological order which, incidentally, also gives some indication ofthe priorities oflife). Today man's most important staple foods are derived directly from seeds as they have been since neolithic times. (It is a sobering thought, as Harlan* has pointed out, that nothing significant has been added to his diet since then. ) From those times he must have learned to collect, conserve and cultivate seeds; and the accumulated experience has been handed down. This book then is part of an ancient tradition, for here we are still primarily concerned with these skills. Seeds are plant propagules comprised of embryos in which growth has been suspended, usually supplied with their own food reserves and protected by special covering layers. Typically they are relatively dry structures compared with other plant tissues and, in this condi tion) they are resistant to the ravages of time and their environment. But resistant is a relative tenn and seeds do deteriorate: the type, the extent and the rapidity of the deterioration, and the factors which control it are important to agronomists, horticulturalists, plant breeders, seedsmen, seed analysts, and those concerned with the conservation of genetic resources.

Download or read book Small Scale Grain Raising written by Gene Logsdon and published by Chelsea Green Publishing. This book was released on 2009-05-12 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1977, this book—from one of America’s most famous and prolific agricultural writers—became an almost instant classic among homestead gardeners and small farmers. Now fully updated and available once more, Small-Scale Grain Raising offers a entirely new generation of readers the best introduction to a wide range of both common and lesser-known specialty grains and related field crops, from corn, wheat, and rye to buckwheat, millet, rice, spelt, flax, and even beans and sunflowers. More and more Americans are seeking out locally grown foods, yet one of the real stumbling blocks to their efforts has been finding local sources for grains, which are grown mainly on large, distant corporate farms. At the same time, commodity prices for grains—and the products made from them—have skyrocketed due to rising energy costs and increased demand. In this book, Gene Logsdon proves that anyone who has access to a large garden or small farm can (and should) think outside the agribusiness box and learn to grow healthy whole grains or beans—the base of our culinary food pyramid—alongside their fruits and vegetables. Starting from the simple but revolutionary concept of the garden “pancake patch,” Logsdon opens up our eyes to a whole world of plants that we wrongly assume only the agricultural “big boys” can grow. He succinctly covers all the basics, from planting and dealing with pests, weeds, and diseases to harvesting, processing, storing, and using whole grains. There are even a few recipes sprinkled throughout, along with more than a little wit and wisdom. Never has there been a better time, or a more receptive audience, for this book. Localvores, serious home gardeners, CSA farmers, and whole-foods advocates—in fact, all people who value fresh, high-quality foods—will find a field full of information and ideas in this once and future classic.

Download or read book Community Seed Banks written by Ronnie Vernooy and published by Routledge. This book was released on 2015-05-15 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Community seed banks first appeared towards the end of the 1980s, established with the support of international and national non-governmental organizations. This book is the first to provide a global review of their development and includes a wide range of case studies. Countries that pioneered various types of community seed banks include Bangladesh, Brazil, Ethiopia, India, Nepal, Nicaragua, the Philippines and Zimbabwe. In the North, a particular type of community seed bank emerged known as a seed-savers network. Such networks were first established in Australia, Canada, the UK and the USA before spreading to other countries. Over time, the number and diversity of seed banks has grown. In Nepal, for example, there are now more than 100 self-described community seed banks whose functions range from pure conservation to commercial seed production. In Brazil, community seed banks operate in various regions of the country. Surprisingly, despite 25 years of history and the rapid growth in number, organizational diversity and geographical coverage of community seed banks, recognition of their roles and contributions has remained scanty. The book reviews their history, evolution, experiences, successes and failures (and reasons why), challenges and prospects. It fills a significant gap in the literature on agricultural biodiversity and conservation, and their contribution to food sovereignty and security.
