บทคัดย่อ (EN): The objectives of the research were to identify seed management practices of the combined-system paddy seed producers as well as to examine the contribution and quality of the combined paddy seed supply system compared with the formal and informal systems. The study was carried out in Udaberagama village of Hambantota district in southern province of Sri Lanka during March to June in 2013. Eighty farmers were randomly selected and categorized based on use of paddy seed systems as belonging to either the formal, informal or combined system. A farm interview survey and seed sampling for quality testing were conducted for each farmer. The farmers’ combined system seed production, involved strategies of both formal and informal sector, they use formal sector seed as basic seeds and many steps of traditional techniques to ensure a good quality seeds. Analysis of the data showed that 35% of local paddy seed requirement was contributed by the combined paddy seed supply system while 16% and 49% were contributed by the formal and informal seed paddy supply systems, respectively. According to the assessment of seed qualities the combined system seeds were significantly different from informal system seeds and met the standard levels for formal system seed with respect to seed germination (87.3%), mixtures with off-types (35.6 no.per 500 grams) and insect and mechanical damaged seed (159.6 no.per 500 grams). Only seed moisture and weed seed levels of combined system seeds did not meet the standard levels for formal system seed. The combined paddy seed supply system can lead to positive impacts in the rice sector through producing and distributing good quality seeds in the local community of southern region of Sri Lanka.
