Futures contracts of mustard seed rose on NCDEX, tracking gains in the benchmark Jaipur market where prices were up due to fresh demand from domestic oil millers and crushers after the recent fall in prices. On NCDEX, the most active July contract was at 3,972 rupees per 100 kg, up 0.86%. A decline in stocks of the oilseed at the exchange-accredited warehouses also supported the contracts.
