Oil mills across the country crushed 425,000 tonne of mustard seed in September, down around 6% from previous month. Crushing of mustard seed in September fell month-on-month because of shrinking arrivals in wholesale markets. Subdued purchases from oil millers and mustard meal exporters also led to lower crushing. Oil mills have crushed about 4.3 million tonne of mustard seed since the start of the crushing season in February compared to total arrivals of 4.6 million tonne during the period.
