Biochemical estimation of different cultivars of turmeric (Curcuma longa L.) grown in Eastern U.P.

Abstract

The current study was conducted in 2011-12 to examine the performance of turmeric cultivars at the Main Experimental Station, Vegetable Science A.N.D.U.A. & T., Kumarganj, Faizabad (U.P.). It was discovered that cultivars NDH-7 and NDH-8 were superior in terms of growth traits including plant height and rhizome/plant output. NDH-8 was the tallest plant (111.2 cm), however NDH-7 had the highest rhizome production per plant (303.00 g). According to the findings, the moisture content varied from 9.4% to 12.2%, with NDH-1 having the highest percentage (12.2%). The range of the total mineral content was 3.39 to 5.30 percent. NDH-7 has the highest mineral concentration (5.30%), followed by NDH-8 (5.16%) and NDH-1 (5.12%). The carbohydrate amount ranged from 65.50 to 71.15 percent, with NDH-8 having the highest carbohydrate level (71.15%). The range for the crude fiber content was 4.05 to 5.24 percent. NDH-8 has the highest crude fiber content (5.24%), followed by NDH-1 (5.18%). The curcumin content varied from 3.7% to 5.9%; NDH-1 had the highest curcumin concentration (5.90 g/100 g), followed by NDH-68 (5.50 g/100 g). The essential oil content ranged from 3.32 to 8.19 percent, with NDH-8 having the highest essential oil level (8.19%). It was discovered that NDH-7, NDH-8, and Prahba were the best cultivars and varieties.
