Abstract:
The experiment was conducted at the Turmeric Research Centre, Agricultural Research Station, Tamil Nadu Agricultural University, Bhavanisagar, Erode district, Tamil Nadu. In terms of the turmeric accessions evaluated at Thoppampalayam in Tamil Nadu, the results indicated the following; The tallest plants were CL-125, CL-197, and BSR-2, with heights of 169.51 cm, 162.98 cm, and 162.46 cm, respectively. The highest number of tillers were observed in CL-197 (7.78), followed by CL-223, BSR-1, and CO-2 (6.99 each), with CL-123 having 5.99 tillers.BSR-1 had the highest number of leaves (9.58), followed by CL-121 (9.13).The longest leaves were found in CL-27 (149.13 cm), CL-225 (148.97 cm), and CL-100 (147.82 cm).The widest leaves were observed in CL-27 (19.22 cm), CL-98 (18.92 cm), and CL-118 (18.13 cm).CL-225 had the most mother rhizomes per plant (5.99), followed by CL-100 (4.99) and CL-95 (4.92).CL-100 had the longest mother rhizomes (11.86 cm), followed by CL-95 (11.62 cm) and CO-2 (10.93 cm).The largest girth of mother rhizomes was in CL-100 (21.09 cm), CL-125 (19.05 cm), and CL-98 (18.98 cm).The heaviest mother rhizomes per plant were in CL-100 (398.38 gm), CL-98 (343.08 gm), and CL-225 (332.63 gm).CL-98 had the highest number of primary rhizomes per plant (46.23), followed by Salem local (33.18) and CL-121 (29.71).Salem local had the longest primary rhizomes (9.98 cm), followed by Erode local (9.95 cm) and CL-225 (9.74 cm).The largest girth of primary rhizomes was in CL-125 (11.31 cm), CL-121 (10.98 cm), and CO-2 (10.91 cm).The heaviest primary rhizomes per plant were found in CL-95 (683.21 gm), CL-225 (657.19 gm), and CL-118 (641.27 gm).The highest number of secondary rhizomes per plant were in CO-2 (27.43), Salem local (24.89), and CL-125 (24.46).CL-125 and CL-197 both had the highest weight of secondary rhizomes per plant (183.45 gm), followed by CL-118 (163.21 gm) and CL-123 (149.23 gm).The total number of fresh rhizomes per plant was highest in CL-98 (65.15), followed by Salem local (60.06) and CL-27 (55.29). The highest total weight of fresh rhizomes per plant was observed in CL-225 (1151.0 gm), CL-118 (1063.4 gm), and CL-95 (1003.7 gm).CO-2 had the highest curcumin content (4.23%), followed by BSR-3 (4.08%) and BSR-2 (3.92%).The highest essential oil content was in CO-2 (4.38%), followed by BSR-2 (3.68%) and CL-258 (3.19%).BSR-3 had the highest oleoresin content (10.02%), followed by CO-2 (9.81%) and CL-121 (9.23%).
