Poppy seed (Papaver somniferum l.) is an important oilseed, whose cultivation has a long tradition in the Czech Republic. Poppy seed grown in the Czech Republic has good quality and, therefore, is preferred to poppy seeds in other parts of the world. The objective of this paper is to characterize the current position of the Czech poppy seed production and foreign trade in the world. Czech Republic is the main world producer of poppy seed and price maker of the European and world prices. With regards to trade, the Czech Republic is also the main producer and seller both in Europe and in the world. The poppy seed crop grown in the Czech Republic is mainly produced for exports, because the domestic consumption consists of only between four and five thousand tons. Major export markets of Czech poppy seed are European countries with a population of Slavic origin or those influenced by Slavic cuisine. Another important markets are overseas countries, that were settled by Slavic immigrants. The paper stresses out the position of the Czech Republic as a major player in the world market with poppy seed. The paper provides analysis of the market position of the Czech production and Czech foreign trade participation. Development of production and trade, as well as some other factors affecting the poppy seed economy, are analyzed such as prices, hectarage, yields, volume of production and volume of trade.
