The cultivation of green forage is extensive and is divided into the categories of temporary and perennial. The temporary includes vetches, pulse, lupine, clover and trifolium; and the perennial, meadow-trefoil, lupinella, sulla (_Hedysarum coronarium_), lucerne and darnel. The natural grass meadows are extensive, and hay is grown all over the country, but especially in the Po valley. Pasture occupies about 30% of the total area of the country, of which Alpine pastures occupy 1.25%. Seed-bearing vegetables are comparatively scarce. The principal are: white beans, largely consumed by the working classes; lentils, much less cultivated than beans; and green peas, largely consumed in Italy, and exported as a spring vegetable. Chick-pease are extensively cultivated in the southern provinces. Horse beans are grown, especially in the south and in the larger islands; lupines are also grown for fodder.
Among tuberous vegetables the potato comes first. The area occupied is about 0.7% of the whole of the country. Turnips are grown principally in the central provinces as an alternative crop to wheat. They yield as much as 12 tons per acre. Beetroot (_Beta vulgaris_) is used as fodder, and yields about 10 tons per acre. Sugar beet is extensively grown to supply the sugar factories. In 1898-1899 there were only four sugar factories, with an output of 5972 tons; in 1905 there were thirty-three, with an output of 93,916 tons.
Market gardening is carried on both near towns and villages, where products find ready sale, and along the great railways, on account of transport facilities. Rome is an exception to the former rule and imports garden produce largely from the neighbourhood of Naples and from Sardinia.
Among the chief industrial plants is tobacco, which grows wherever suitable soil exists. Since tobacco is a government monopoly, its cultivation is subject to official concessions and prescriptions. Experiments hitherto made show that the cultivation of Oriental tobacco may profitably be extended in Italy. The yield for 1901 was 5528 tons, but a large increase took place subsequently, eleven million new plants having been added in southern Italy in 1905.
The chief textile plants are hemp, flax and cotton. Hemp is largely cultivated in the provinces of Turin, Ferrara, Bologna, Forlì, Ascoli Piceno and Caserta. Bologna hemp is specially valued. Flax covers about 160,000 acres, with a product, in fibre, amounting to about 20,000 tons. Cotton (_Gossypium herbaceum_), which at the beginning of the 19th century, at the time of the Continental blockade, and again during the American War of Secession, was largely cultivated, is now grown only in parts of Sicily and in a few southern provinces. Sumach, liquorice and madder are also grown in the south.
