Description |
Four field trials and four pot culture trials were conducted during 2007-2008 and 2008-2009 at Indian Institute of Horticultural Research, Bangalore for soil and nutrient management studies in Coleus vettiveroides. Application of 100:50:50 NPK kg ha-1 recorded significantly higher plant growth (50.86 cm), biomass accumulation (32.75 t ha-1) , and nutrient uptake (uptake of 50.60 kg N, 7.21 kg P, 126.04 kg K ha-1) of C. vettiveroides at 116 days after planting (DAP). C. vettiveroides plants grown in 18 inch diameter with 30 inch length PVC column produced significantly higher total root yield (315.2 g plant-1) and biomass accumulation (3597.2 g plant-1) at 121 DAP. Growth media comprising of sand and soil mixed in equal proportion (100 kg) added with 0.5 kg Farm Yard Manure (FYM) recorded significantly higher biomass accumulation (782.34 g plant-1 and 1653 g plant-1) of C. vettiveroides in cement pots and PVC columns respectively at 135 DAP. Application of FYM (282.80 g plant-1) or inorganic fertilizer (312.73 g plant-1) along with bio-fertilizer recorded higher biomass accumulation of C. vettiveroides as compared with sole application of FYM (210.49 g plant-1) or inorganic fertilizer (261.56 g plant-1) at 130 DAP. Significantly higher root yield (3.16 t ha-1), biomass accumulation (49.66 t ha-1) and nutrient uptake (uptake of 50.13 kg N, 7.75 kg P, 119.11 kg K ha-1) of C. vettiveroides recorded with application of recommended FYM (10 t ha-1) + recommended NPK (100:50:50 NPK kg ha-1) at 140 DAP. Application of Mucuna mulch 10 t ha-1 recorded significantly higher plant growth (51.74 cm) and application of FYM mulch 10 t ha-1 recorded higher biomass accumulation (33.37 t ha-1) and nutrient uptake (uptake of 49.30 kg N, 9.41 kg P, 148.74 kg K ha-1) of C. vettiveroides at 139 DAP. The different chemical constituents identified in oil of root of C. vettiveroides are hydrocarbons (ß-Himachalene etc), oxygenated compounds like alcohols (Vellerdiol, Isothujol etc), aldehydes (ß-Cyclocitral, etc), esters (Sabinyl acetate, etc), ketones (ß-Ionone, Traseolide etc). |
