Wheat prices may rise further because farmers in India, the world's second-biggest grower, may harvest a smaller crop after dry weather delayed planting. The crop may decline 5 per cent to as low as 72 million metric tonnes in the March-April harvest from 75.8 million tonnes a year earlier, S Pramod Kumar, president of Karnataka Roller Flour Mills Association, said yesterday. That's less than the government estimate of 74.8 million tonnes.
