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.
