Prices of mustard seed rose in Jaipur due to strong demand for mustard oil in the ongoing monsoon season. In Jaipur, the benchmark market, prices of the oilseed rose 10-15 rupees to 4,210-4,225 rupees per 100 kg. Prices of mustard oil were up at 854 rupees per 10 kg, compared with 780 rupees on previous close. However, a rise in arrivals was insufficient to meet the demand from domestic stockists and oil millers, which supported prices.
