Abstract : Presently study was undertaken for the determination of biomass, productivity and yield of three plant species, viz, Mangifera indica, Psidium guajava and Dalbergia sissoo under the influence of gaseous emission in Jaunpur city. The biomass, productivity and yield of plant species found to be higher at each sampling date of the control plant species than the polluted one. Plant species exposed to SO2 (0.07 ppm to 0.14 ppm) showed greater variation in relative growth of root (-4.8 to 17.80%) and shoot (-19.16 to 48.50%). Maximum relative growth reduction occurs in P. guajava and minimum in D. sissoo. Maximum productivity and fruit yield found in M. indica and minimum productivity in P. guajava and minimum fruit yield in D. sissoo, after 60 days exposure of 0.07 and 0.14 ppm of SO2 at different age of plant species (210, 225, 240, 255 day ages).
