Experiments were conducted to know the inorganic compound absorption of leaf, and the organic component, oil content, fatty acid composition of seeds by different fertilizer levels and growth stage of Pungn-yeonggage. Ripening rate and seed yield were highest under the standard of nitrogen fertilizer level. Nitrogen and potassium amount of leaves were highest at 20 days after seedlings, but there was no difference in phosphate between growth stages. Absorptions of nitrogen and potassium were increased by applying double amount of nitrogen fertilizer. Oleic fatty acid content was found highest under the double amount of nitrogen, phosphate and potassium fertilizer level, and linoleic fatty acid content was increased with double amount of phosphate fertilizer level.
