There have not been many studies on technical measures in growing Mesona chinensis Benth for

high yield and quality. Hence, a research on the effect of the fertilizer combination on the growth,

yield and quality of Mesona chinensis Benth was conducted by the research team in Bac Kan in

2019. The experiment consists of 4 formulas: F1 (2.0 tons of micro-bial compose + 35 kg N + 32

kg P2O5 + 60 kg K2O/ha), F2 (2.5 tons of micro-bial compose + 26 kg N + 24 kg P2O5 + 45 kg

K2O/ha), F3 (3.0 tons of micro-bial compose + 18 kg N + 16 kg P2O5 + 30 kg K2O/ha), F4 (3.5

tons of micro-bial compose + 9 kg N + 8 kg P2O5 + 15 kg K2O/ha. The study results showed that

using the 2nd fertilizer combination has the highest crop yield and economic efficiency.

Specifically, the 2nd fertilizer combination has a viscosity of 4.4 cP, pectin content is 0.7 mg/ml,

leaf yield reaches 62.67 tons/ha.
