New Delhi, 26 February (NNS): Here, the prices of coriander badami slipped by Rs 100 to Rs 8100 per quintal owing to the weak buying from the stockists even after the feeble prices. During the weekend, the prices have gone up in the same ratio. The arrivals rose to 12000/13000 bags in the Ramganj mandi and the prices held stable at the level of the previous day. The active contract went up by Rs 44 or 0.57 percent to Rs 7824 per quintal due to the increased speculative buying. There is no possibility of more uptrend in the spot coriander prices during the coming one or two days.
