Available in PDF, EPUB and Kindle. Book excerpt: Indian agriculture has witnessed spectacular advances in agricultural production in the last few decades. This was possible through green revolution in mid 60s leading to the country’s remarkable achievement in food grains and edible oil production. Seed has always been regarded as the most vital, basic and critical input in agriculture. It is interesting to note that today seed demand of only 10% farmers is met. Efforts are needed to provide good quality certify seeds to farmers. In recent years the awareness for seed health has increased among the growers, traders, and consumers. In post-GATT era and with emergence of WTO, seed health has assumed the global concern. Infection of seed borne pathogens results into seed rots, seedling decay, pre and post emergence mortality, distortion, discoloration, reduced seed size and shrivelledness of seeds. Their study and identification is primarily required to achieve satisfactory control. The book will be of great help to students, researchers, and people engaged in seed production activities. In this book, information about different seed borne diseases is presented in 20 chapters. There is an urgent need to find out effective, alternative methods of diseases control, which are less harmful to human beings and environment. There are chapters dealing with botanical pesticides and quarantine regulations. A chapter describes molecular aspects involved in seed borne diseases. The contents are divided into two parts (I) Seed borne diseases and (II) Wilt and foliar diseases and their control methods. Ecofriendly measures to control seed borne diseases are dealt in detail. The book provides comprehensive and integrated information on management of seed health written by experts in the field. It will be especially useful for students and young people involved in seed testing, seed industry as well as in teaching.

Book Synopsis SEED QUALITY ENHANCEMENT : PRINCIPLES AND PRACTICES by : Kalaivani, S.
Download or read book SEED QUALITY ENHANCEMENT : PRINCIPLES AND PRACTICES written by Kalaivani, S. and published by Scientific Publishers. This book was released on 2010-07-01 with total page pages. 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.
Book Synopsis Seed Production of Agricultural Crops by : A.F. Kelly
Download or read book Seed Production of Agricultural Crops written by A.F. Kelly and published by Scientific Publishers. This book was released on 2013-10-01 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed is common fundamental to the production of all crops. Though many books have been written about the importance of using seed which is viable and free from weed seeds and diseases. The necessity is felt for the need to preserve the generic quality of seed during multiplications. Wigh the production of ever more sophisticated cultivars the work of the seed producer becomes of increasing importance. High seed yields are not enough in temselves and we need to arrange production in such a way that the qualities which give each cultivar a special place in agricultural production are preserved from one generation to the next. The book mainly emphasis on the precutions which the seed producer should take to ensure the production of good quality seed in the widest sense. The author studied the various problems, beginning with the definition of a cultivar and ending with stored seed ready for planting. This book is essentially practical, contins enough basic information to enable reader to understand the reasons behind the management practices which are descibed. It is hoped that the book will be useful to those who are involved in agricultural education, crop production into seed production, to extnesion workers and administration in seed programmers and to the practical seed producers.
