The experiment was carried out at Herbal Garden of Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during the rabi seasons of 2023-24 and 2024-25. The suitable experimental design was laid out on Randomize Block Design (RBD), where in 8 Treatments and 3 Replications were carried out on the field, Treatments included combinations of recommended doses of nutrients (RDN), farmyard manure (FYM), and vermicompost to compare the impact of integrated and sole nutrient applications. The treatments were divided into fertilization application of T₁ (100% RDN (150: 60: 60 N: P₂O₅: K ₂O kg ha-¹), T₂ 75% RDN, T₃ 50% RDN, T₄ 75% RDN + 5 t fym ha-¹, T₅ 50% RDN + 10 t fym ha-¹, T₆ 75% RDN + 1 t Vermicompost ha-¹, T₇ 50% RDN + 2 t Vermicompost ha-¹ and T₈ Control. Mentha’s vegetative growth and yield attributes, with T₆ (75% RDN + 1 t vermicompost ha⁻¹), T₅ (50% RDN + 10 t FYM ha⁻¹), and T₇ (50% RDN + 2 t vermicompost ha⁻¹) performing the best in terms of fresh herbage yield (up to 419.4 q ha⁻¹) and oil yield (up to 286.5 kg ha⁻¹). Treatment T₆ (75% RDN + 1 t vermicompost ha⁻¹) recorded the highest net return (1,73,604 Rs ha^-1) and benefit: cost ratio (2:0), followed closely by T₁, T₇ and T₅. Although T₁ (100% RDN) had a high gross return, its cost of cultivation was also higher, reducing overall profitability.
