ASSESSING BIODRAINAGE POTENTIAL OF TROPICAL FOREST TREES THROUGH LYSIMETER EXPERIMENTS IN CENTRAL INDIAAvinash JainAbstract The lysimeter experiments with seven tropical forest tree species were conducted in nonâweighing type lysimetric tanks. Waterlogged conditions were artificially created in the tanks at 0-0.25 m, 0.25-0.50 m and 0.50 -0.75 m levels. Water consumption, growth characteristics and transpiration rate of trees planted in the tanks were recorded and Pearson correlation among different parameters was established. E. hybrid and P. pinnata showed steady rate of transpiration, more water use and higher growth under waterlogged conditions, hence recommended for raising plantations to reclaim waterlogged sites along canal command areas with almost similar climatic conditions. The biodrainage potential of the selected tree species was found in the order E. hybrid> P. pinnata> A. lebbek> A. procera> D. sissoo> T. arjuna> A. nilotica. |
