The Annual Report on the General Administration of the Cooch Behar State for the Year 1934-1935 is the volume of the annual administration reports of the princely state of Cooch Behar for the year to 31 March 1935. Five members of the Regency Council submitted it to the Maharani, as Regent and President of the Council. It was printed at the Cooch Behar State Press in 1935. Its excise chapter gives the year's figures for ganja, whose duty in the State moved with Bengal's.

Written by the State's government for its Regent, the volume is evidence of how that administration reasoned about its revenue from intoxicants as much as it is a record of cannabis. read more →

Comparison of self-pollination and intercrossing for feminized seed production in Thai Hang Kra Rok cannabis (Cannabis sativa L.) landrace

Compares selfing with intercrossing for producing feminized seed from two Thai landrace accessions of Hang Kra Rok cannabis, one from Bangkok and one from Sakon Nakhon. Female cuttings were treated with colloidal silver to induce male flowers, and the progeny were grown in a plant factory with artificial lighting. Both selfed lines and the Sakon Nakhon by Bangkok cross gave 100% female plants, while the reciprocal cross produced one hermaphrodite (5.6%). Dry inflorescence weight did not differ between treatments. The Bangkok selfed line had the highest THC content at 6.58%. The plants were grown under artificial light, so the chemistry is not field chemistry.
