Virtually all wheat grown in the country is a hard red winter wheat of
good quality, somewhat softer than durum wheat. Cultivation of durum
wheat has been almost completely abandoned because of its low yield. The
possibility has been suggested, however, that production of durum may be
resumed eventually on the basis of newly developed, more productive
varieties. Durum wheat requirements for the manufacture of noodles,
semolina, and other products have been imported against payment in
foreign currencies.

Increases in the output and yields of crops were reported to have been
achieved through the introduction of improved plant varieties and seeds,
better cultivation practices, expanded irrigation, greater use of
fertilizers, and more effective disease and pest control. The supply of
fertilizers to agriculture, in terms of plant n
