In the 1980s, statistics on Libyan agricultural production continued to vary widely. For example, figures compiled by the Central Bank of Libya generally exceeded those published by the UN Food and Agriculture Organization by 10 to 100 %. During the 1980s, wheat and barley were the principal cereal crops, although millet was also grown in the southern oases. Both crops were cultivated throughout the nation, in the coastal regions as well as in the desert oases. The optimum yield for wheat cultivation in Libya was thought to be about 5 tons per hectare, but by the mid1980s yields were only averaging about 0.5 ton per hectare. Citrus production declined to inremarkable levels following the government's water conservation measures of 1976. Other valuable crops were dates, olives, melons, onions, and potatoes. Vegetables were grown in specialized farms near Tripoli. Tree crops remained popular because many farmers combined olive, date, apple, or almond raising with cereal production.
Until the 1970s, cattle were used mainly for transport. During the 1970s, the number of cattle--particularly dairy cattle-- increased, as did milk and meat production. By 1985 there were nearly 209,000 head of cattle in the nation, and several fodder plants were in various stages of completion as part of an effort to achieve self-sufficiency in animal feedstuffs. The General Dairy and Dairy Products Company was created in 1974 to take over most private dairies and to produce and market all dairy products. Private dairy farms were permitted to operate, but their milk had to be sold to the state company. The government also entered the poultry business on a large scale, and independent farmers found it difficult to compete against the large government poultry farms.
