Futures contracts of barley fell on the NCDEX due to profit booking after prices hit a 21-month high of 1,800 rupees per 100 kg. The October contract was at 1,791 rupees per 100 kg, down 8.50 rupees. However, gains in the benchmark market of Jaipur, following improved demand from domestic stockists, limited the fall. Demand rose after the government had hiked the minimum support price of the coarse grain by 30 rupees per 100 kg.
