The field experiment to study the possibility of growing Japanese mint as intercrop with maize under irrigated condition was undertaken during kharif 2016-17. The experiment was laid out in randomized block design with three replications. There are eight treatments viz., T1: Maize (45 cm / 75 cm x 20 cm) + Japanese mint (120 cm x 15 cm) (2:1), T2: Maize (45 cm / 75 cm x 20 cm) + Japanese mint (25 cm / 95 cm x 15 cm) (2:2), T3: Maize (120 cm x 10 cm) + Japanese mint (30 cm / 60 cm x 15 cm) (1:3), T4: Maize (90 cm x 15 cm) + Japanese mint (90 cm x 15 cm) (1:1), T5: Maize (90 cm x 15 cm) + Japanese mint (30 cm / 60 cm x 15 cm) (1:2), T6: Maize (60 cm x 20 cm) + Japanese mint (60 cm x 15 cm) (1:1), T7: Sole maize (60 cm x 20 cm) and T8: Sole Japanese mint (45 cm x 15 cm). The treatment T3 recorded significantly higher LER (1.5), ATER (1.4), Japanese mint equivalent oil yield (312.4 kg/ha) and maize grain equivalent yield (252.5 q/ha) with maximum B: C ratio (3.34) among the intercropping systems. However, dry matter production (51.5 g/plant) and fresh herbage yield (150.0 g/plant and 20.5 t/ha) was significantly higher in sole Japanese mint (T8). The study showed that Japanes mint can be grown profitably with maize as intercrop in 1: 3 row proportion with adjustment in cropping geometry of maize.
