Available in PDF, EPUB and Kindle. Book excerpt: Now in Paperback “A fantastic guide for organic seed breeders and producers. [Navazio] has taken organic seed production to a higher level.” —Suzanne Ashworth, author of Seed to Seed The Organic Seed Grower is a comprehensive manual for the serious vegetable grower who is interested in growing high-quality seeds using organic farming practices. It is written for both home seed savers and diversified small-scale farmers who want to learn the necessary steps involved in successfully producing a seed crop organically. Detailed profiles for each of the major vegetables provide users with practical, in-depth knowledge about growing, harvesting, and processing seed for a wide range of common and specialty vegetable crops, from Asian greens to zucchini. In addition, readers will find extensive and critical information on topics including: • Seed-borne diseases • The reproductive biology of crop plants • Annual vs. biennial seed crops • Isolation distances needed to ensure varietal purity • Maintaining adequate population size for genetic integrity • Seed crop climates • Seed cleaning basics • Seed storage for farmers • and more . . . This book can serve as a bridge to lead skilled gardeners, who are already saving their own seed, into the idea of growing seed commercially. And for diversified vegetable farmers who are growing a seed crop for sale for the first time, it will provide details on many of the tricks of the trade that are used by professional seed growers. This manual will help the budding seed farmer to become more knowledgeable, efficient, and effective in producing a commercially viable seed crop. Written by well-known plant breeder and organic seed expert John Navazio, The Organic Seed Grower is the most useful guide to best practices in this exciting and important field.

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 Seed certification and maize rice and cowpea productivity in Nigeria An insight based on nationally representative farm household data and seed company location data written by Hiroyuki, Takeshima and published by Intl Food Policy Res Inst. This book was released on 2022-12-15 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the potential importance of seed quality to agricultural productivity growth, many governments in sub-Saharan Africa lack the capacity to expand quality assurance systems even where there is expressed interest. This study aims to evidence the value of quality assurance systems with an analysis of efforts to produce and distribute certified seed in Nigeria. We assess the associations between quantities of certified seeds produced and spatial variations in production locations proxied by headquarter locations of seed companies producing certified seeds, on the one hand, with spatial variations in the use of certified seed, yields, and output at the farm level, on the other hand. Our analysis covers three crops that are important to food security in Nigeria: maize, rice, and cowpea. Our analysis integrates information on seed quantities produced and locations of seed companies with nationally representative panel data from a survey of farm households and spatially explicit rainfall and temperature data. We find a positive relationship between certified seed production in proximity to farm households and farm-level use of certified seeds, yields, and output, although this effect is diminishing at the margin. These diminishing marginal effects may be partly due to two factors. First, the yield gains from certified seeds tend to vary considerably within each state, suggesting that either quality issues persist in the seed supply chain or farmers are not using complementary inputs or appropriate management techniques when using quality seed. Second, it may be that as certified seed becomes more available to farmers, its use spreads from higher-return farms to lower-return farms, thereby diminishing the gains on the extensive margin. Although more rigorous assessments of causal effects and cost-effectiveness are needed to validate these findings, these results are consistent with the hypothesis that there are diminishing returns to seed quality assurance. Policymakers, regulators, and seed providers may benefit from identifying optimal, crop-specific target quantities or rates for certified seed production rather than aiming for certification of all seed produced in a market.

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.
