Abstract: A field experiment was conducted at Medicinal and Aromatic Plants Unit, Saidapur Farm, Department of Horticulture, College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka to study the effect of planting methods and nutrition on growth, yield and essential oil content in vetiver (Vetiveria zizanioides (L.) Nash Syn. Chrysopogan zizanioides) during July 2015- July 2016. The experiment was laid out in split plot design with three main plot and six sub plot comprising of eighteen treatment combinations with two replications. The main plot consisted of three planting methods; P1– Ridge and furrow method, P2– Bed method and P3– Bag method. The sub plot consisted of six fertilizer levels; F1- 25:25:25 kg NPK/ha, F2- 50:25:25 kg NPK/ha, F3- 75:25:25 kg NPK/ha, F4- 25:50:25 kg NPK/ha, F5- 50:50:25 kg NPK/ha and F6- 75:50:25 kg NPK/ha. For all the treatments, farm yard manure @ 10 tonnes per ha was applied. Among the planting methods, bag method (P3) recorded significantly higher plant height (181.6 cm), number of tillers per plant (110.3), number of leaves per plant (737.1), number of roots per plant (317.0), dry root weight (95.1 g/plant), dry root yield (4085.8 kg/ha) and essential oil yield (85.3 kg/ha) compared to other planting methods. Among fertilizer levels, 75:50:25 kg NPK/ha (F6) recorded significantly higher plant height (180.1 cm), number of tillers per plant (111.2), number of leaves per plant (739.2), number of roots per plant (261.0), dry root weight (86.3 g/plant), dry root yield (3686.5 kg/ha) and essential oil yield (78.4 kg/ha) compared to other fertilizer levels.
