How to grow tulsi (holy basil) commercially for the herbal market?

Tulsi, or holy basil, is a low input aromatic and medicinal crop grown for dried leaf, herb and tulsi oil, with strong demand from ayurvedic and herbal companies. Grow it from seed raised seedlings transplanted onto well drained soil; it is hardy, needs moderate water and few chemicals, and matures for first cutting in about three months, after which you take multiple cuttings. The herbage is dried for leaf and seed sale, or distilled for oil. It is well suited to UP and many regions and works on small plots. Returns are modest but steady with low cost, and contract farming with herbal manufacturers is common, which helps secure the market. As with other medicinal crops, fix a buyer or sell through an established herbal mandi rather than planting on speculation. Use good seed, dry the leaf cleanly to preserve quality, and confirm current rates and any contract terms before scaling.
