India's wheat production may cross 90 million tonnes (mt), an all-time high, in the 2011-12 crop year surpassing the earlier estimate on the back of favourable weather condition, a top agriculture ministry official said. According to the second advance estimates for the 2011-12 crop year (July-June), wheat production is estimated at record 88.31 mt. The expected rise in production could lead to an increase in the foodgrain production in 2011-12 crop year.
