Four density treatment (60,000 plant/ha, 50,000 plant/ha, 40,000 plant/ha, 35,000 plant/ha) and 3 fertilizer treatments were designed in a split - plot included 3 replicates. The analytical results show that most of the parameters have statistical significance (p ≤ 0.05) when comparing among these treatments. The number of flower cluster per plant of the treatments M4P2, M2P2 and M4P1 was significantly higher than that of the treatments M1P1, M1P3 and M1P2. The treatments M2P1, M2P3, M3P1, M3P2, M3P3, and M4P1 shows no statistical difference (p >
0.05). Treatment M2P2 showed the highest seed yield (66.4 kg/ha), significantly higher (p ≤ 0.05) than that the treatments M3P2 and M3P3. The treatment with the lowest seed yield was M4P3 with a value of 57.5 kg/ha. The number of ralative flower cluster was positively correlated with the seed yield. Treatment M2P2 has the most advantages, therefore they may be applied in the Hanoi conditions. However, further studies at different locations and seasons will be important for future local recommendations.
