Abstract: A field experiment entitled “Effect of micronutrients application on morpho-Physiological, biochemical parameters and essential oil yield of mentha (Mentha arvensis L.)”. The experiment was conducted at Department of Plant Physiology, Agricultural Biochemistry and Medicinal and Aromatic Plants, IGKV, Raipur (C.G.) in Mentha arvensis L. during the 2020-21 Rabi season. Randomized block design (RBD) was used to conduct the experiment with three replication. There was 10 treatments T1 (Control, Water Spray), T2 (FeSO4 @ 300 ppm), T3 (FeSO4 @ 500 ppm), T4 (FeSO4 @ 700 ppm), T5 (CuSO4 @ 300 ppm), T6 (CuSO4 @ 500 ppm), T7 (CuSO4 @ 700 ppm), T8 (ZnSO4 @ 300 ppm), T9 (ZnSO4 @ 500 ppm), T10 (ZnSO4 @ 700 ppm). Herbage yield ranged from 16.06-20.18 t ha-1. The maximum herbage yield was recorded in T6 (20.18 ton ha-1) herbage yield in T9 (19.43 ton ha-1) was statistically at par with T6 and the minimum herbage yield was observed in T1 (16.06 t ha-1). Essential oil (%) ranged from 0.64-0.78 %. The highest essential oil (%) was obtained in T9 (0.78%) which was at par with T6 (0.77%), and the lowest essential oil (%) was recorded in T7 (0.64%).
