Wheat is logging its biggest weekly drop since 2011 as traders reassess the outlook for supplies of the grain.
The price of wheat for July delivery fell 4 cents, or 0.6 percent, to $6.74 a bushel on Friday. The grain has fallen for eight straight days and is down 6.6 percent this week, its biggest such decline since September 2011.

In other trading of farm products, corn and soybeans fell.
Metals were mixed. Silver and platinum dropped while copper and palladium rose. Gold was flat.
In energy trading, the price of oil rose.
