Abstract: Turmeric is an important spice, medicinal and cosmetic crop of south Asian countries being propagated through rhizomes requiring huge quantity of seed rhizome (2500 kg ha-1) which accounts for 20-22% of production cost. An experiment was conducted to optimize type of seed rhizome and method of multiplication under shade house conditions at Agronomy Research Farm, CSK HPKV, Palampur during 2017 and 2018. The experiment was laid out in completely randomized design (CRD) consisting of four treatments and five replications. Significantly higher germination percentage (92.0 and 92.8%) and germination index (2.53 and 2.21) were noticed in seedlings raised in portrays using primary rhizome during both the years. Besides, better growth attributes viz., seedling height (13.32 and 13.58 cm), root length (10.64 and 11.18 cm) and seedling vigor index (2204 and 2219) were also recorded during both the year in turmeric seedlings raised through primary rhizomes in portray as compared to seedlings raised using mother rhizome in portray or polybag and seedlings raised in poly bag using primary rhizome. Significantly higher total dry matter accumulation (2.59 g plant-1), root dry weight and root to shoot ratio (0.41 and 0.51) were observed in seedlings raised in poly bags. For raising turmeric seedlings primary rhizomes and portray found to be better propagating material and method, respectively than mother rhizomes and polybag. Shifting from rhizome planting to transplanting of turmeric seedlings in mid hills of Himalayan region is expected to conserve 80% of the seed material besides saving the expenditure on weeding and irrigation. Transplanting of turmeric seedling may also help in resource conservation along with better resource use efficiency and sustainability.
