Abstract
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. The analyzed results showed that the 100% Farm Yard Manure (FYM) gave higher growth of Mentha such as plant height, number of leaves and branches, leaf area, dry matter accumulation, crop growth rate, fresh herbage yield, and oil content were recorded along with nitrogen uptake and content. Simultaneously, Karanj tree parameters such as diameter at breast height (DBH), total height, canopy spread, pod characteristics, seed weight, and oil content were also evaluated. Results showed that integrated nutrient management (INM) significantly enhanced 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).
