production and seed science and technology
aspects in relation to Seed Act
By the end of the course, the students will be able to
i. understand the concepts of quality seed production of different field and vegetable crops
ii. study about different classes of seed and maintenance of genetic purity during seed production
iii. learn about seed certification procedure, seed drying, processing, cleaning, testing, packaging, storage, marketing etc.
