| Abstract | The study was conducted to determine the effects of air pollution on growth and yield of mung bean (Vigna radiata L, var. Khampang Sean 1) grown at Agricultural System Research Farm of Asian Institute of Technology, Bangkok, Thailand during 13th of September 2008 to February 2009 using open top chambers. Air monitoring was done for O₃, NO₂ and SO₂ in filtered chambers, non filtered chambers and open plots. Mean ozone concentration during the experimental period in the experimental site ranged from 0.006 to 0.008ppm in the FCs, 0.186 to 0.32ppm in NFC and 0.16 to 0.47ppm in the open plots (OP). NO₂ concentration ranged from 7.15ppb to 9.5ppb in FCs 30.3 to 38.6ppb in NFCs and 25.7 to 70.9ppb in open plots. S02 concentration ranged from 0.5 to 0.6ppb in FCs, 11.3 to 40.7ppb in NFCs and 17.4 to 28.1 ppb in OPs. Plants grown in filtered chambers showed higher shoot dry weight, leaf area, number of leaves, plant height, number of flowers per plant, number of pods per plant and 1000-seed weight than open plots and non filtered chambers. Total proline content was higher in open plots and non filtered chambers than filtered chambers indicating oxidative stress from air pollutants. Yield increment of 70% was observed in plants in filtered chambers than open plots and non filtered chambers. This study concluded that air pollutants have detrimental effect on growth and yield of mung beans. Therefore, measures to mitigate air pollution effects are necessary to be developed and adopted to increase crop yield. |
