New Delhi, 28 February (NNS): The prices of coriander badami rose by Rs 200 to Rs 8300 per quintal owing to the increased sale at the lower level. There were about 8000/9000 bags of coriander reported to arrive in the Ramganj mandi and the prices held firm at the level of the previous day. The active contract softened by Rs 8 or 0.10 percent to Rs 8030 per quintal due to the sluggish speculative buying. The spot coriander prices will likely to remain strong during the coming one or two days.
