Crop increased on Friday and it is set for the largest weekly gain since July 2012 as planting in the world's largest exporter of corn and wheat, U.S., slowed and crop conditions worsen amid bad wet weather in the region. Wheat for delivery in July advanced 0.3% to $7.31 a bushel on the CBOT and it is heading to add 5.6% this week, while Corn with delivery in the same month was at $6.6125 a bushel, set to rise 6.7% this week.
