摘要

Food security depends on seed security,and in countries where subsistence fanning still predominates,the ability to improve farm production is severely handicapped by a lack of supply of quality seeds.Farmers require access to seeds which are genetically and physically pure,free from problem weeds and seed-borne diseases,and have high germination and seed vigour.The Seed Chain,when properly operated,provides an assurance of adequate supplies of seed of the required quality,but unfortunately Seed Chain problems still exist in many countries.The financial and environmental benefits of reduced tillage methods for crop establishment are well recognized,and there is now a range of modular plot/small scale seeders which can be used for reduced tillage and conventional crop establishment,available for developed,transitional and developing agricultural economies.However,improved seeding technologies demand high seed quality.Seeding equipment and seed quality are inexorably linked,and the development of the former and supply of the latter must at all times meet the needs of the end-user.
