ASSESSMENT OF THE GROWTH, DEVELOPMENT AND CURCUMINOID CONTENT OF CURCUMA LONGA L. VARIETIES SAMPLE IN THANH HOA

Abstract

The experiment was conducted to evaluate the growth, yield and curcuminoid
content of 17 sample of C. longa L. varieties. The research results show that plant samples
collected from many regions in the country grow and develop well in the climate conditions
in Thanh Hoa. The comparison among the varieties showed that: C. longa L. NBG1 had the
highest medicinal tuber yield of 41.30 tons/ha, followed by the C. longa L. NNB2 with 37.85
tons/ha. C. longa L. NTN1 gave the highest curcuminoid content at 10.67% (curcuminoid
yield, reaching 687,72 kg/ha, was high after NTN2). C. longa L. NTN2 yielded the highest
curcuminoid, reaching 863,82 kg/ha (8.77% Curcuminoid). C. longa L. NTN2 was not
infected with pests and diseases of leaf. Curcuma longa L. NTN2 had the advantage of
