Systemic studies on the different germplasms of turmeric (Curcuma longa L) in West Bengal

The present investigation entitled “Systemic studies on the different germplasms of Turmeric (Curcuma longa L ) in West Bengal” was conducted at Horticultural Research Station, Mandouri, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal during 2013-14 and 2014-15. The design adopted was Randomised Block Design (RBD) having 3 replications with 13 treatments. The germplasm under evaluation were RCE-3, Rajendra Sonia, Duggirala, Alleppy Supreme, Roma, NH-l, Suranjana, BSR-2, Pratibha, Kedaram, Rashmi, Megha Turmeric, Midnapur local. The investigation revealed that Maximum plant height (1.29 mt) was recorded in Rajendra Sonia and it was minimum(0.8 mt) in Midnapur ( local cv.). Leaf production varies from 9.09-18.61 and it was highest in Roma. Maximum leaf length was recorded in Rajendra Sonia (48.58cm) and it was minimum in Midnapur (local cv.) (27.77cm). The result obtained in this investigation clearly showed that maximum weight of mother rhizomes per clump(120.23gm),primary rhizome per clump( 143.83 gm), minimum weight of mother rhizome per clump(74.22gm), primary rhizome per clump(80.67 gm) .On the other hand maximum yield per ha was obtained in the germplasm Rajendra Sonia (31.965 ton/ ha) and it was minimum in Midnapur( local cv.) (14.285 ton/ha). In qualitative character the curcumin percentage was recorded highest with germplasm RCE-3 (4.21%) followed by Rajendra Sonia(4.075%) and it was minimum in Kedaram( 1.015%)
