Abstract

Environmental pollution poses a great health hazard to human beings, animals and plants. Industrial effluents and acid rain are the major pollutants that have a strong influence on the growth of crop plants. A pot trial was conducted to investigate the influence of industrial effluents and simulated acid rain (SAR) on the growth, productivity, biochemical and quality attributes of mungbean crop. The experiment was comprised of various treatments i.e. T0 = Control; T1 = industrial effluents (25%) + distilled water (DW) (75%); T2 = industrial effluents (50%) + DW (50%); T3 = industrial effluents (75%) + DW (25%); T4 = pure industrial effluents (100%) and T5 = acid rain (HCl at pH 3.5). Results revealed that maximum increase in chlorophyll contents (12.88%), pods per plant (27.90%), nodules per plant (34.78%), number of grains per pods (33.33%), 1000-seeds weight (8.53%) and seed yield (47.65%) was observed in T2 as compared to control. Significant increase in the grain metals contents was observed in the T4. However, application of SAR significantly decreases chlorophyll contents (14.11%), pods per plant (30.23%), nodules per plant (47.82%), number of grains per pods (33.33%), 1000-seeds weight (7.01%) and seed yield (51.40%) as compared to control. In crux, simulated acid rain and pure form of industrial effluents have toxic effect on the growth, yield and quality of mungbean. The adequate dilution of effluents treatment is therefore needed before the disposal and reuse of wastewaters for irrigation purposes.
