It included the quotas of sugar production there, its prices and changes on the market. The latest sugar production data in the world was also given. The main companies carrying out activities on the Polish sugar and sugar beet seeds were also presented.New circumstances after liberating the sugar market in the EU in October, 2017, were also presented. Nowadays, Poland has been a great potential country for further technological progress in agricultural holdings and growing performance in sugar processing and production industry. As food export from Poland increases, it will be followed by increasing use of sugar. Examples are given to improve sugar beet productivity. 展开更多
