The present study has been undertaken to study the effects of simulated acid rain on two important food crops grown widely in India. Most of the investigations on the effects of acid precipitation made so far are based on local vegetation. The main objective is to characterize a relative growth and yield response of these leguminous crops to different concentration of simulated acid rain. The legumes are important food crops for human beings as they are good source of protein, carbohydrate and fats. This research studied the effect of Simulated Acid Rain on plants, growth components of Green Gram and Bankla. Green Gram (Moong Vigna radiata linn willzeck cvk 851 and Bankla Vicia faba Linn cv all green (Broad bean)) are belong to Leguminaceae sub family Papilionaceae. Simulated acid rain was prepared with different concentrations of H₂SO₄ and HNO₃ in the ratio 7:3. The plants were exposed to simulated acid rain of pH 2.5, 3.5, 4.5 and 5.5 with control. The morphological changes including plant height, days and time taken in flowering (No, of days), number of leaves were recorded. All the morphological parameters taken in this study showed decrease trend with decrease pH (increase in acidity). The yield of Moong and Bankla decreased due to acidic rain
