Evaluation of turmeric (Curcuma longa L.) genotypes for yield and quality characters under high altitude and tribal zone of Andhra Pradesh

Abstract

To identify the best genotype suitable for High Altitude and Tribal Zone of Visakhapatnam, an experiment was carried out with nineteen genotypes of turmeric in Randomized Block Design with three replications during Kharif 2017 at Horticulture Research Station, Dr. Y.S.R.H.U, Chinthapalli, Visakhapatnam District. The maximum fresh weight of rhizomes per plant was recorded in CLA-3 (658.32 g), maximum dry weight of rhizomes per plant was recorded in CLA-5 (123.14 g) and maximum yield per plot was observed in CLA-3 (15.10 kg), whereas the minimum was recorded in CLA-10 (8.04 kg). The maximum estimated fresh rhizome yield per hectare was recorded in CLA-3 (50.35 t) and the lowest in the genotype CLA-10 (26.80 t). The maximum dry recovery percentage was recorded in CLA-6 (27.86%) and CLA-11 recorded the highest curcumin content (5.35%) and oleoresin content of rhizomes (10.13%) compared to other genotypes under HAT zone conditions.
