Abstract:
A field experiment was carried out during the year 2016 at the Agroforestry Research Centre, Patharchatta, G.B. Pant University of Agriculture and Technology, Pantnagar to study the difference in herbage and oil yield of different Mentha species when intercrop with poplar. The experiment was laid out in Factorial Randomized Block Design (RBD) with two farming systems i.e. Mentha species intercropped with 4-year old poplar stand and Mentha species as sole crop with four replications. Four species of Mentha were M. arvensis, M. piperita, M. spicata and M. citrata in. Vegetative parameters of different Mentha species such as plant height and plant spread were maximum under open compared to poplar based agroforestry system. The maximum total fresh herbage yield was 263.50 q ha-1 in M. arvensis under open whereas, M. piperita recorded the maximum total fresh herbage yield of 122.71 q ha-1 under poplar. Maximum oil content of 1.24 and 1.38% was obtained in M. arvensis at 1st and 2nd harvest, respectively under open conditions. Similarly, under agroforestry system also, this species recorded maximum oil content of 0.91 and 0.89% at 1st and 2nd harvest, respectively. Total oil yield was maximum in open farming system as M. arvensis produced highest oil yield of 343.71 l ha-1 under open and 100.29 l ha-1 under poplar based agroforestry system
