Evaluation of zingiber officinale roscoe (ginger) oil and its productivity under gmelina arborea based agroforestry system

The field experiments were conducted under Gmelina arborea based agroforestry system at experimental plot of TFRI, Jabalpur, M.P. The Zingiber officinale (Ginger), a shade loving commercially cash crop was grown under seven year old plantation of Gmelina aborea. The observations were recorded on growth and yield parameters of Z. officinale during the study period. The study revealed that growth and yield of Zinger crop was higher under intercropping system and lower in monoculture (Sole) system. Ginger oil was found maximum in monoculture (Sole) system while it was lower in intercropping system. The study indicates that Gmelina shade favours only yield of Ginger not for its active ingredient i.e. essential oil, which is important component in several medicinal drugs.
