Performance evaluation of selected turmeric (Curcum longa L.) landraces prevailed in Karnataka (India) for growth, yield and quality attributes

Abstract

A field experiment was conducted at College of Horticulture, Bengaluru, Karnataka, India during 2020-21 to evaluate the performance of twenty four land-races and two check varieties of turmeric. The results revealed that though released variety Prabha recorded highest plant height (141.10 cm) and Prathibha recorded highest curcumin (6.23%) and oleoresin (13.33%) contents whereas landrace TC-8 possessed highest number of leaves per clump (35.60), tillers per clump (8.40), leaf area (307.56 dm2) and leaf area index (22.78) at 150 days after planting and produced maximum computed fresh rhizome yield (52.88 t ha-1) and cured yield (13.17 t ha-1). Hence, the landrace TC-8 is found to be best for Eastern dry zone of Karnataka.
