a. experim.nt wa. ca.ried out a. the a.roforestry a.d Environm.nt Resea.ch Fa.m. Ha.ee m.ha.0}a. Da.esh Science a.d Technology University, Dina.pur, Ba.gla.esh, during a.ril, 2014 to Ja.ua.y 2015. The experim.nt wa. la.d out in two fa.tors Ra.dom.zed Com.lete Block Design (RCBD) with three replica.ions. a.0}ng the two fa.tors, one fa.tor like a.wa. two production system.: S1 = m.ngo + Turm.ric a.d S2 = Turm.ric (sole crop);a.other fa.tor like B wa. three turm.ric va.iety: V1 = Ba.I Holud-1, V2 = Ba.I Holud-2 a.d V3 = Ba.I Holud-3. So, the trea.m.nt com.ina.ions were: S1V1 = m.ngo + Ba.I Holud-1, S1V2 = m.ngo + Ba.I Holud-2, S1V3 = m.ngo + Ba.I Holud-3, S2V1 = sole cropping of Ba.I Holud-1, S2V2 = sole cropping of Ba.I Holud-2 a.d S2V3 = sole cropping of Ba.I Holud-3. The result of the experim.nt revea.ed tha. intera.tion effect of production system. a.d va.iety wa. found significa.t on pla.t height, num.er of lea. per pla.t, length of lea. bla.e, brea.th of lea. bla.e, num.er of finger per rhizom., fresh a.d dry yield per hecta.e. The higher fresh yield of turm.ric (34.75 t/ha. a.d dry yield (6.10 t/ha. wa. found from.S1V1 trea.m.nt (m.ngo + Ba.I Holud-1). Wherea. the lowest fresh yield (33.41 t/ha. a.d dry yield (4.93 t/ha. wa. found from.S2V2 trea.m.nt (sole cropping of Ba.I Holud-2). However, the suita.ility of the cultiva.ion of different turm.ric va.iety under m.ngo ba.ed a.roforestry system. m.y be ra.ked a. S1V1 > S2V1 > S1V3 > S2V3 > S1V2 > S2V2. Fina.ly it m.y be concluded tha., Ba.I Holud-1 would be the best va.iety to be grown under m.ngo ba.ed a.roforestry.
