The field study was conducted to determine the effect of different dates of planting (1st October, 1st November and 1st December) and different cultivars (Kosi, Kushal, Sambhav, Saksham and Himalaya) on growth, yield and quality of menthol mint planted during rabi 2017– 2018 in split design with three replications under Northern dry zone of Karnataka. The results revealed that growth parameters like plant height, spread and number of branches (63.30, 52.11 cm and 25.92, respectively) and yield parameters like fresh and shade dried herbage yield (9.04 and 7.23 t/ha), oil yield and content (80.08 kg/ha and 1.09 %) recorded maximum when crop planted on 1st November irrespective of cultivars. Among different cultivars cv. Kushal was superior in terms of growth, yield and quality parameters, which recorded maximum plant spread and number of branches (49.32 cm and 23.63), fresh and shade dried herbage yield (9.91 and 7.93 t/ha) and oil yield (76.49 kg/ha), while cv. Saksham recorded maximum oil content (1.04 %) and menthol content (71.65 %). The maximum net returns (₹ 81,158.00/ha) and B: C ratio (2.76) were obtained when cv. Kushal planted on 1st November 2017-2018.
