Nitrogen fertilization levels of Labisia pumila Blume during the experiment.

Nitrogen (kg N/ha) 1,2	Total nitrogen fertilizer per plant 3 (g)
0	0.00
90	0.36
180	0.72
270	1.08

¹Nitrogen source used was urea (46% N);

²Every nitrogen treatment receives TSP (Triple super phosphate; 46% P) and MOP (muriate of potash; 60% K) at standard rates of 180 kg N ha⁻¹; the nitrogen was split into three fertilization phases, and each phase was about 33.3% of total nitrogen fertilizer;

³Every nitrogen treatment receives TSP (triple super phosphate; 46% P; 0.72 g per plant) and MOP (60% K; 0.51 g per plant) at standard rates of 180 kg N/ha.
