New Delhi, 05 July (NNS): The prices of coriander badami remained firm at Rs 8000 per quintal owing to the sluggish sale at the higher level. Recently, the prices have gone up by Rs 300/400 per quintal. There are about 4000 bags of coriander reported to arrive in the Ramganj mandi of Rajasthan and the prices remained firm at the level of the previous day. The active contract went down by Rs 18 or 0.27 percent to Rs 6662 per quintal because of the weak speculative buying. The spot coriander prices may likely to remain strong during the coming days.
