Abstract:
Aromatic crops are gaining importance as economically more lucrative crops than many traditional agricultural crops in different agro-ecosystems. Patchouli crop is a long duration aromatic crop. Patchouli oil is hence an important ingredient in many fine fragrance products such as perfumes, as well as in soaps and cosmetic products. There is need to optimum nutrient management practices and plant growth hormone levels for optimum growth, oil yiled of patchouli The experiment treatments were divided into ten treatment in randomized block design with three replications under All India Coordinated Research Project on Medicinal and Aromatic plants, Raipur centre. The treatments comprised of control (T₁-RDF: 150:50:50 kg NPK ha^-1), 100:50:50 kg ha^-1 NPK + 2.5 t ha^-1 vermicompost (T₂), T₁ + 20 ppm NAA, T₁ + 30 ppm NAA, T₁ + 20 ppm GA, T₁ + 30 ppm GA, T₂+20 ppm NAA, T₂+30 ppm NAA,T₂+20 ppm GA and T₂+30 ppm GA. Maximum mean plant height (93.27cm), herbage yield (16.18 q/ha) and oil yield (36.96 kg/ha) were found with application of 100:50:50 kg ha^-1 NPK + 2.5 ton ha-1 vermi compost + 20 ppm GA which was superior over application of 100:50:50 kg ha^-1 NPK + 2.5 ton ha^-1 vermi compost + 30 ppm GA, 100:50:50 kg ha^-1 NPK + 2.5 ton ha^-1 vermi compost + 30 ppm NAA, 100:50:50 kg ha^-1 NPK + 2.5 ton ha^-1 vermi compost + 20 ppm NAA. The application of 100:50:50 kg ha^-1 NPK + 2.5 ton ha^-1 vermicompost +20 ppm GA gave highest mean net return (Rs.43,086 ha^-1) followed by 150:50:50 kg ha^-1+ 30 ppm GA(Rs 42,106/ha).
