The introduction of the spice plant coronarious gingerlily (Hedychium coronarium) from tropical South Asia to Central Asia was successful. In order to promote the flower yield a good proportion of the fertilizers applied is required. The authors found out that the rational formula of N: P2O5 : K2O was 3.4 : 1 : 3 .1, so an annual per ha dosage of after manuring with 127 kg of N, 3.8 kg of P2O5 and 117.6 kg of K2O was desirable. When the planting density was 5 clumps per square meter, the yield of fresh flower per ha could reach 36.085 tons.
