The research has been conducted to evaluate additional rate of nubitions Mg and B in combination with same base of liming (CaO) amending the soil for flue cured tobacco onto poor soil quality area at Cao Bang in 2011 and 2012. The results in this study has been following abstracts
Supplel,11enting nubitions Mg and B with same base of liming (CaO) amending the soil obviously improved not only the quality of tobacco material (Increasing good grade
improving aroma, tast, strength, ... ) and enhanced significantly but also tobacco leaves yield
nubient regime promising improvement for the material of flue cured tobacco has involved following key factors: Liming (1 ton CaO/ ha) amending the soil in combination with application of fertilizer rate 60 N + 80 P2O5 + 120 K2O + 60 Mg + 2 B (kg/ ha).
