A pot experiment was conducted to study the effects of arsenic containing irrigation water on growth, yield and nutrient accumulation of Vigna radiata (mung bean) in two different soils - one is non calcareous and non saline (Sara soil series) and the other is calcareous and slightly saline (Barisal soil series). The levels of arsenic used in irrigation water were 0, 1, 2, 5 and 10 ppm. Root and shoot growth parameters, yield and nutrient accumulation were studied to assess the effect of arsenic. All the growth parameters responded better at 2ppm concentration in both soils. The parameters of growth and yield studied, almost all showed to be drastically affected by 10ppm treatment. Accumulation of all the studied nutrients in shoot decreased while accumulation of iron increased with increasing arsenic concentrations.
