New Delhi, 29 October (NNS): International demand for Indian dry ginger remains consistently strong. Recently, its prices increased by Rs 500 to Rs 34500/35000 per quintal. Adequate supplies of raw ginger for grinding and drying are not available, affecting stocks of dried ginger. Production declines in major producing countries such as Nigeria have also weakened availability in international markets. With the onset of winter, domestic demand is expected to increase. Considering the upcoming festive season, further price gains are anticipated.
