Jordan announced today that it was restoring diplomatic relations with Egypt. An Egyptian official said late tonight that King Hussein of Jordan had telephoned President Hosni Mubarak of Egypt this evening to congratulate him on the eve of the Islamic New Year Wednesday and to inform him that the Jordanian Cabinet had decided to resume diplomatic relations. Jordan, one of 17 Arab nations that severed diplomatic relations with Cairo after President Anwar el-Sadat signed a peace treaty with Israel in 1979, is the first to announce that it would resume diplomatic ties with Cairo. Egypt Sees 'Positive Step' Among Arab countries, only Oman, the Sudan and Somalia maintained diplomatic relations after the Camp David accords of 1978 between Israel and Egypt.

Argentina and the International Monetary Fund have come to terms on a program of austerity for that country that could make available billions of dollars in fresh credits from both the I.M.F. and commercial banks. A spokesman for Jacques de Larosi ere, managing director of the I.M.F., said today that he had decided to recommend that the fund's board of governors approve the accord, which was painstakingly drafted by the I.M.F. staff and officials in Buenos Aires. The recommendation by the head of the 148-nation agency is almost certain to lead to board approval, thus bringing to a successful conclusion negotiations that have been under way for nearly a year and removing a major uncertainty from the international financial scene. Disclosure by Grinspun The announcement was made initially by Argentina's Economy Minister, Bernardo Grinspun, in a speech to the 39th annual joint meeting here of the World Bank and the fund. Mr. Grinspun's statements were confirmed by Mr. de Larosi ere's office.

Under this heading, The Times amplifies articles or rectifies what the editors consider significant lapses of fairness, balance or perspective.

Putting a glass of orange juice on America's breakfast tables has become a multibillion-dollar business, dominated by a handful of giant processors such as Minute Maid and Tropicana. So large and voracious are their appetites for oranges that the processors consider it vital to assure themselves of a steady flow of fruit at relatively steady prices. In that respect, the deadly canker disease in oranges could not have come at a worse time for the state of Florida, this country's traditional producer of oranges for juice. In recent years, Florida has been unable to guarantee the big processors their supply, in part because of erratic weather. Increasingly processors have looked abroad, most notably to Brazil, and the canker scare can only accelerate this trend, industry experts say. When and how much the canker outbreak will affect prices at the supermarket is not yet known. So far, some big juice processors say they have yet to feel a supply curtailment. ''Not at all - at least not yet,'' said Timothy J. Clarke, a spokesman for Tropicana.
