A field study was conducted during 2015-16 to investigate the effect of row spacing (30 cm, 45 cm and 60 cm) and nitrogen levels (50, 100, 150 and 200 kg/ha) on growth of Japanese mint (Mentha arvensis L.). The result revealed that between 45- 90 days after planting, the highest absolute growth rate (1.13 g/plant/day) was recorded at 60 cm row spacing. While, the crop growth rate (6.87 g/m2/day) was highest at 30 cm row spacing. Highest nitrogen content in plant (2.05 %) was recorded at wider row spacing of 60 cm. While, the nitrogen uptake was highest (90.51 kg/ha) at closer row spacing of 30 cm. Between 45- 90 after planting, the highest absolute growth rate (1.14 g/plant/day), crop growth rate (6.04 g/m2/day), nitrogen content in plant (2.40 %) and nitrogen uptake (115.16 kg/ha) were maximum with the application of 150 kg N per ha.
