Agriculture in Germany is a small sector of the German economy. It has declined in importance during the 20th century and by 1989 amounted to only 1.6 percent of the West German GDP. Although agriculture's share of East German GDP was twice as high as in the west, even after the two economies are completely united, agriculture's share of GDP is expected to amount to only about two percent. However, despite the sector's small size, it remains politically important. Potatoes and grain were their main agricultural product.
The number of farms had decreased steadily in West Germany, from 1.6 million in 1950 to 630,000 in 1990. In East Germany, where farms were collectivized under the socialist regime, there had been about 5,100 agricultural production collectives with an average of 4,100 hectares under cultivation. Since unification, about three-quarters of the collectives have remained as cooperatives, partnerships, or joint-stock companies. The others were returned to their original owners - if those owners could be found - or were privately sold, becoming about 14,000 private farms. In western Germany and in the newly privatized farms in eastern Germany, family farms predominate. For the 630,000 farms, there are 750,000 full-time employees. There are also, however, many more part-time employees, and most farms do not represent their owners' full-time occupation.
Although the number of farms has declined, production has actually increased through more efficient production methods. By the early 1990, a single farmer could produce enough food for seventy-five people, far more than was the case in the 1950s or 1960s.
Agricultural products vary from region to region. In the flat terrain of northern Germany and especially in the eastern portions, cereals and sugar beets are grown. Elsewhere, with the terrain more hilly and even mountainous, farmers produce vegetables, milk, pork, or beef. Almost all large cities are surrounded by fruit orchards and vegetable farms. Most river valleys in southern and western Germany, especially along the Rhine and the Main, have vineyards. Beer is produced mainly, but not exclusively, in Bavaria. Wine is produced mainly, but not exclusively, in Rhineland-Palatinate.
