A field experiment was conducted at Research Farm of the Indira Gandhi Agricultural University, Raipur, from mid-January to the last week of August during 2001 and 2002, to find out the effect of harvesting intervals on herbage and oil productivity of different varieties of Japanese mint (Mentha arvensisL.) under Chhattisgarh condition. ‘Himalaya’ variety gave significantly higher mean herbage, oil yield and net returns when it was harvested at 120 days after planting and 75 days after first harvest. In case of ‘Koshi’ variety, the maximum herbage and oil yields and net returns were obtained when it was harvested at 110 days after planting and 75 days after first harvest.
