Raw data of evaluation of turmeric genotypes for physico-chemical properties in Salyan, Nepal

Turmeric (<i>Curcuma longa</i>) is an important rhizomatous spice crop with good nutritive and medicinal values. With the increasing production of turmeric in Nepal, its export is also increasing. However, the quality of turmeric products has not been up to international standards. In view of solving this problem, an experiment was conducted to evaluate the physico-chemical properties of different turmeric genotypes at the Ginger Research Program, Kapurkot, Salyan in April 2024. The experiment was carried out in a completely randomized design with 11 genotypes, each replicated 3 times. Parameters such as dry recovery %, powder recovery %, bulk density, moisture content of rhizome, pH content, essential oil, and curcumin content were observed. The data was tabulated in MS-Excel and analyzed using R-Studio Version 4.3.3. The inference was drawn at a 5% level of significance, and mean comparisons were made using DMRT. Result showed that curcumin content, essential oil content, and p^H ranged from 2.81% (KH-2) to 6.07% (Cl 9803), 5.60% (Cl 0209) to 8.33% (Cl 9803), and 6.17 (Cl 0209) to 6.50 (Cl 0207 and Cl 1312), respectively. Dry recovery and powder recovery percentages ranged from 13.89% (Cl 9802) to 18.90% (Cl 9805) and 12.95% (Cl 9802) to 17.94% (Cl 9805), respectively. The highest bulk density was observed in Cl 0201 (1.07 g/cm³), and genotype Cl 9802 (87.05%) had the highest moisture percentage in the rhizome. Overall, the genotype Cl 9803 was identified as the best genotype for production.
