A field study was conducted during 2015 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 and yield of Japanese mint (Mentha arvensis L.). The result revealed that at harvest, the row spacing of 60 cm (S3) recorded higher stem girth (11.29 mm) and more number of leaves per plant (906.30). At 90 DAP, highest leaf area (6601.17 cm2 /plant) was recorded in row spacing of 60 cm (S3). Row spacing of 60 cm (S3) recorded maximum essential oil content (0.93 %). Whereas, the higher oil yield per hectare (176.22 kg) was observed at 30 cm row spacing (S1). At harvest, application of 150 kg nitrogen per hectare (N4) recorded maximum stem girth (11.31 mm) and leaves per plant (894.10).At 90 DAP, the physiological parameters like, leaf area (6206.27 cm2/plant), leaf are index (3.22) were maximum with the application of 150 kg N per ha (N3). Maximum essential oil content (0.96 %) and oil yield per hectare (169.46 kg) was noticed with the application of 150 kg nitrogen per hectare (N3).
