ABSTRACT

Dust is a serious atmospheric pollution and it is becoming a major pollutant owing to automobile pollution. Dust particles impose negative effects on humans, animals and plants. Therefore, this study was executed to determine the impact of foliar applied dust particles on growth, morho-physiological and biochemical traits of soybean crop. In the present study soybean plants were subjected to different treatments; control (no dust spray), 3 g/L dust spray, 6 g/L dust spray and 10 g/L dust spray. The results indicate that maximum soybean root and shoot growth, seed weight and grain yield was observed in control linked with better relative water contents (RWC), photosynthetic pigments and synthesis of osmolyte (TSP and FAA) and reduction oxidative stress markers. All levels of dust particle treatment particularly, 10 g/L dust spray significantly reduced the growth and yield traits of soybean by reducing photosynthetic pigments, TSP, FAA and membrane stability.
