Effect of different nitrogen levels on the yield and oil quality with economic parameters of mint (Mentha arvensis L.)

The present investigation has been carried out at main experiment station, Department of Horticulture, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya, Uttar Pradesh, India, to find out the effect of different nitrogen levels on the yield and oil quality with economic parameters of mint, in randomized block design (RBD) with nine treatment combinations and replicated thrice. Observation on various parameters, viz., fresh herbage yield (199.60 quintal/hectare), dry herbage yield (39.92 quintal/hectare), oil yield (177.61 liter/hectare), and oil % (0.88) content in mentha oil were noted maximum due to application of nitrogen, 140 kg/hectare. From the experiment, it is concluded that a higher economic return was obtained fresh herbage yield (199.60 quintal/hectare), dry herbage yield (39.92 quintal/hectare), oil yield (177.61 liter/hectare) with the application of nitrogen, 140 kg/hectare. It would be very helpful to the farmers for economic importance and subsequently pharmaceutical industry for getting raw material to eradicate disease and increase vitality.
