Abstract: Field experiments were conducted during 2007-10 at various farmer’s field of Dzongu valley of North Sikkim district of Sikkim to identify locally available different forest plant suitable for leaf material for using as bio-mulching under rain-fed condition as farmers practices for the main objectives: to identify best leaves for control moisture loss, optimized temperature, soil erosion, weeds and disease incidences, increased germination, quality yield and economy in organic ginger (Zingiber officinale Rosc.) local cv. Bhaisey. Green leaves of Artemisia vulgaris Linn., Schima wallichii Korth., Chromolaena odorata (L.) R.M.King & H.Rob. syn. Eupatorium odoratum Linn., Alnus nepalensis D. Don and mixed leaves were used traditionally as bio-mulches in  organic  ginger seeding in field. The longest rhizome size (7.25 cm), No. of rhizome fingers/plant (39.23), more ginger yield (208.54 q/ha), B:C ratio (1:1.80), lowest incidence of diseases (16.10%), recorded significantly maximum soil moisture conservation (44.75%) and optimum soil temperature (24.80 0C) were recorded significantly under the Schima wallichii fresh leaves for bio-mulching as compared to all other bio-mulching material in organic ginger production and economic under rain-fed condition of NE hills. The leaves of Schima wallichii used as bio-mulch in organic ginger increased in yield (60%) and net return (134.50%) as compared to without mulching (control).
