The effects of saline water irrigation and waterlogging on the growth and nutrient contents of 19 vetiver ecotypes were
investigated. Plant height, tiller number, and dry biomass were recorded at 12 months after planting. The results indicated that
plant growth and development were influenced by saline water irrigation and waterlogging conditions and were different among
the vetiver ecotypes. The accumulation of sodium in the shoots was higher than in the roots under salinity conditions that would
be of benefit as vetiver can be used to remove salt contamination from soil or water. Under waterlogging conditions, total
phosphorus had a higher concentration in the roots due to the effect of root oxygen stress on phosphorus uptake. We screened 8
vetiver ecotypes that showed salt and flood tolerance. These ecotypes would be of benefit for crop improvement with the best
available plant material in our breeding program.
