Prices of mustard seed rose in Jaipur due to improved demand from oil millers and crushers amid a fall in arrivals. In Jaipur, the benchmark market, prices of the oilseed rose by 20-25 rupees to 4,230-4,250 rupees per 100 kg. Arrivals of mustard seed in Rajasthan fell by 5,000 bags (1 bag = 85 kg) to 60,000 bags. Strong demand for mustard oil in the ongoing monsoon season also supported prices of the seed.
