The experiment were conducted to “Study of different rhizome size and treatment on turmeric (Curcuma longa L.)” at the Department of Seed Technology, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushingar during Kharif 2021-22. The experiment was laid out in Randomized Complete Block Design (Factorial concept) with three replications of GNT 2 variety comprising seven treatments and four rhizome size. The rhizome R4 ( motherrhizome) and treatment T4 (Chiller treatment 4°C for 2 hrs.) revealed that all traits reported. In these investigation mother rhizome given significantly maximum result for germination per cent (80.48%), plant height (64.52 cm), leaf length (36.96 cm), leaf width (13.50 cm), tillers plant^-1 (3.21), mother rhizome plant^-1 (2.32), primary finger plant^-1 (7.33), secondary finger plant^-1 (7.94), rhizome length (14.89 cm), rhizome width (15.54 cm) and rhizome weight (185.25 g) while, in case of different treatments chiller treatment (4°C for 2 hrs.) given significantly maximum result for germination per cent (85.98 %), plant height (65.35 cm), leaf length (34.51 cm), mother rhizome plant^-1 (2.38), Primary fingers plant^-1 (6.70), secondary fingers plant^-1 (7.95), rhizome length (14.13 cm), rhizome width (15.58 cm) and rhizome weight (187.23 g). Maximum leaf width (12.96 cm) and the number of tillers plant^-1 (3.24) found by Sodium hypochloride treatment (4% for 2 hrs.) T5.
