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).
