Futures contracts of coriander on the NCDEX extended gains and hit a 6-week high because of a likely decline in output in 2016-17 (Oct-Sep). The most active April contract on the NCDEX traded up 0.5%. Coriander output may be hit due to the late onset of winter followed by lower than normal temperatures in Rajasthan in mid-January and on expectation of above-normal temperatures later this month. Arrivals in Rajasthan were pegged at 45,000 bags (1bag=40kg) up 13,000 bags.
