When is Kalmegh sown and how long until harvest?

Kalmegh is usually a monsoon season crop. Seed or nursery raised seedlings are established around the start of the rains, and the crop is harvested at the flowering to early seed stage, roughly 4 to 5 months later, because the active content is high around flowering. It is harvested by cutting the whole leafy plant above ground. Being a single short season crop, it fits well after or alongside the kharif plan and frees your land for the next crop. Time the harvest to the recommended flowering stage your buyer wants for active content, not too early and not too late. Confirm the exact sowing window and harvest stage with your KVK for your district, since this affects both yield and quality.
