Unseasonal rains in Rajasthan over the last three days have not caused much damage to the coriander crop so far but likely spells of heavy rainfall in the key growing areas pose a threat. 30-40% of the mature coriander crop still standing and forecast of rainfall this month has kept growers and traders on edge about likely damage to the harvest. Coriander crop in some areas of Jodhpur and Barmer districts in the state may see some quality erosion in the form of discoloured grains though the production volume may remain unchanged. Rainfall in Rajasthan is likely to bring colour variations in the standing crop of Badami and Eagle varieties of coriander.
