Futures contract of mustard seed hit a two-month-high of 3,657 rupees per 100 kg because of strong demand for the edible oil and seed for crushing. On NCDEX, the July contract was at 3,642 rupees per 100 kg, up 0.8% from previous close, while the most-active August contract was up 0.9% at 3,682 rupees. Higher demand for the edible oil has led to an increase in oilseed purchases, and is supporting upside in mustard seed prices.
