Seed Technology, CropSc 314, Pratima Poudel, Assistant Professor, HICAST Seed Technology Course Code: CropSc 314 The terms “seed and seed technology” means the parts of the plants commonly used for propagation and determine the nature of seed sector, its multiplication, production and supply Seed is a living plant embryo. It breathes and undergoes constantly the process of ageing (metabolism) in field and storage. It is a link between plant generations as a carrier of gene, a planting material for regeneration and a basic and vital input in agriculture. Difference between seed and grain Crop production for various purposes i.e. seed or grain depending upon its planting value. The following are the main differences between seed and grain, when they are used for sowing S.N Seed Grain 1. Result of well-planned seed programme, sound scientific knowledge, organized effort, investment on processing , storage and marketing facilities It is the part of commercial product and no such knowledge and efforts are used 2. Production and maintenance of quality is the main aim of seed producer, must be true to its type. During production effort is made to rogue out off types, diseased plants objectionable weeds and other crop plants at In case of grain production, maximizing of yield is the main aim of produces so may not be true to type and also purity and health status may be inferior
Seed Technology, CropSc 314, Pratima Poudel, Assistant Professor, HICAST appropriate stage of crop growth which ensures satisfactory seed purity and health 3 History or pedigree of the seed is ensured Varietal purity is unknown 4. Field inspection is done properly by the seed inspector in seed producing plot in different stages of crop No any scientific inspection is done in the growing period of crop 5. Seed is scientifically processed, treated, packed and labeled with proper lot identity Processing and labeling is not scientific 6. Seed testing (Germination test, Purity, seed health and seed moisture) is done before planting Routine seed testing is not done before planting Seed Technology Feistritzer (1975) defined seed technology as the methods through which the genetic and physical characteristics of seed could be improved. It involves such activities as variety development, evaluation and release, seed production, processing, storage and certification. The seed technology is essentially an interdisciplinary science which encompasses a broad range of subjects. Seed technology comprises techniques of seed production, seed processing, seed storage, seed testing, certification, marketing and
Seed Technology, CropSc 314, Pratima Poudel, Assistant Professor, HICAST distribution and their related research on these aspects. It is an interdisciplinary science, which deals from varieties release to all aspect of seed handling. Plant breeder, agronomist, botanist, pathologist, entomologist and physiologist can work together on the various aspects of seed technology. Role of seed technology 1. Seed- carrier of new technologies 2. Seed – a basic tool for secured food supply 3. Seed- the principle means to secure crop yield in less favourable production area 4. Seed – a medium for rapid rehabilitation of agriculture in cases of natural disaster Goals of seed technology: 1. Rapid multiplication 2. Time supply 3. Assured high quality of seed 4. Reasonable price Opportunities of seed technologist 1. Management of seed enterprise 2. Seed testing laboratories 3. Seed certification agencies 4. Seed law enforcement agencies 5. Training/ extension centers ( for seed growers) 6. Research institute ( where seed technology research being done) Scope of seed technology 1. Food supply 2. Income generation opportunity
