The objective of the experiment was to study the effect of clove oil dosage on controlling storage weevil C maculatus F., and maintaining seed qual ity including seed viability and seed vigor of two soybean cv after three months storage duration. The experiment was conducted in Laboratory of Seed Technology ,Faculty of Agricul ture Padjadjaran University, Jatinangor, Sumedang, West Java, from March until May 2009. The experiment design used was Split Plot Design consist of two factors and replicated three times. The main factor was cultivar of soybean, were Anjasmoro ( big size seeds) and Sindoro ( medium size seeds). The sub factor was bio protectant of clove oil dosage, which consist of five levels, were : without clove oil, 0.5 mL kg-1 soybean seed, 1.0 mL kg-1 , 1.5 mL kg-1 soybean seed, and 2.0 mL kg-1 soybean seed. All of the experiment consist of 45 units experiment , where every experiment unit used 75 g of seed. Seeds and five pairs of storage weevil were fill in plastic cup and placed in plastic container during three months storage. The result of experiment showed that there were interaction effect between cultivars and dosage of clove oil on seed damage percentage after three months storage, but there were no intercation effect on another parameters was observed. Sindoro has better storability than Anjasmoro, as indicated by weevil population, seed damage percentage, germination capacity, vigor index and seed moisture content. Dosage of clove oil 5 mL/kg soybean seed showed better affected on suppression of storage weevil and maintaning seed viabilty and vigor.
