Yield and Yield Components of Turmeric (Curcuma Longa L.) Genotypes

Abstract

Collection, evaluation and characterization of turmeric (Curcuma longa L.) genotypes prevailed in Southern Karnataka was carried out during 2018-19 and 2019-20 of Kharif season. Over 66 turmeric genotypes were studied to elucidate morphometric and genetic diversity. A significant difference among the genotypes for growth, yield and quality traits was recorded for all the traits was observed. Result from the pooled data, the maximum number mother rhizomes, primary fingers and secondary finger was found with genotype 13.65, and 18.96). Along with the highest fresh weight of mother rhizome, primary and secondary finger was also recorded with 302.72 and 210.23 g). Genotype TC-36 registered maximum girth and length of mother rhizomes, primary and secondary finger (14.19, 8.49 and 6.18 cm; 9.99, 9.23 and 7.56 cm). The maximum fresh rhizome yield (49.27 t ha -1 ), curing percentage (25.77) and cured yield (12.70 t ha -1 ) was also registered with TC-36. Overall from this evaluation data the genotypes viz., TC-36, TC-61, TC-60-2, TC-60, TC-51, TC-27, TC-33, TC-37, TC-19 and TC-21 contributing towards yield and perform well in southern region of Karnataka. These genotypes need to be studied in larger field trials for their stability to growth, yield and quality and also in multilocation trail.
