The publication provides information on the results achieved in 2004 in agriculture, forestry and food industry. We assured the comparability of time-series in connection with the pocketbooks published in the recent years. Besides the national and branch indicators and data, the principal agricultural data are also given in details by counties. The international data are suitable to demonstrate the main trends. With the English and also with the German and French publication of the pocketbook we wanted to render help to the foreign partners of the Hungarian agricultural institutions, research institutes and economic organizations. The published data are compiled on the basis of the publications of the Central Statistical Office, EUROSTAT, the Food and Agricultural Organization (FAO) and the Research Institute for Agricultural Economics.
