    Abstract


    The application nitrogen fertilizer aim to define sensible nitrogen dose for tuberous root yield of mondo grass on Ferralic Acrisols at Phu Tho province. The application nitrogen dose change from 30 to 50 kgN/ha + 10 tons organic fertilizer +  30kg P2O5 + 30kgK2O/ha. Mondo grass was researched on   growth of foliate, root and tuberous root yield.  Results showed that:  the dose of nitrogen fertilizer applying on  30kg N + 10 tons organic fertilizer +  30kg P2O5 + 30kgK2O/ha  achieved the max tuberous root yield and economic effectivity. The tuberous root yield of mondo grass achieved 33,08 ton/ha. The income achieved  850,792 million VND/ha/3 years and investable effectivity of nitrogen fetilizer - 38,52 fold.
