Crop losses due to pollutant stress are on the rises ever since industrial growth is made. Most of industrial effluents contain lot of toxic substances. When these effluents, without proper treatment are discharged to any land mass or aquatic system cause serious problems to all biological life. Many places in Tamilnadu especially the Erode town is a well known textile industrial place and these industries produce several tons of effluents containing toxic dyes and chemicals, which often are discharged into river with or without proper treatment. These water sources are used for irrigation in the agricultural sector, facing great problems of crop loss and low yield. Aim of the study is thus to expose the serious effects of textile effluents on their mode of action on the survival and growth of some vegetable crops, like Tomato, Peas, beans, Fenugreek and Mustard which cause damage to the parts of plants earlier and later to the whole plant. In the present study, the leaves of the effluent treated plants showed drastic alteration in the carbohydrates, protein, ammonia, glutamine, nucleic acids and phenol content. The deviation of all these biochemical constituents indicates the adverse effect of these pollutants on the normal physiology. Hence, measures can be taken to restrict the effect of these effluents on the most significant vegetable crops.
