Bargain buying and short covering lifted U.S. corn futures on Monday after the market slid to contract lows on expectations for strong U.S. output, traders said.

Corn/soybean yields unchanged
Seasonal weakness, rains pressure barley
Midwestern conditions favourable
Some areas receive deluge; others still dry
But imports drop over last two years
Area, stocks reports have little influence
Quarterly stocks data also out
Weather, supply pressures weigh on grains
