ENVIRONMENTAL REQUIREMENTS FACTOR REQUIREMENTS Soil type Sandy loam is preferred. Clay loam is acceptable, but clay not. Slightly sloping land avoids waterlogging in case of over watering. Flat site is acceptable, Topography but watering must be monitored to avoid waterlogging, that will stunt the growth of young plantlets. Mature vetiver, however, thrives under waterlogged conditions. Absorbs dissolved nutrients like N and P. Is tolerant to sodicity, magnesium, aluminium Nutrition and manganese pH Accepts soil pH from 3.3 to 12.5 (in another publication its 4.3-8.0) soil conditions tolerant to salinity Absorbs dissolved heavy metals from polluted water. Is tolerant to As, Cd, Cr, Ni, Pb, Hg, Heavy metals Se and Zn. Light Shading affects vetiver growth (C4 plant), but partly shading is acceptable. tolerant to temperatures from -15 °C to +55°C, depending on growing region. 25°C is the optimal soil temperature for root growth. Root dormancy occurs under a temperature of 5°C. Shoot growth is affected earlier, at 13°C is only very little shoot growth, but root Temperature growth is continued at a rate of 12.6 cm/day. Under frosty conditions, shoots become dormant and purple, or even die, but the underground growing points survive and can re-grow quickly if the conditions become better. tolerant to drought (because of its deep roots), flood, submergence; annual precipitation Water of 6.4 - 41.0 dm is tolerated, but it has to be at least 225 mmSubmitted by : Monisha pattnaik 2011JDS6009 IIT DELHI
