When needing nutrient elements hold suitable degree for plants, they performed their physiological and biochemical processes properly and so there will be no need to use defensive mechanism. In doing so, its growth and function level increases. In this study, effect of shortage nutrient elements (Nitrogen, Phosphorus, Potassium, Magnesium and Calcium) on antioxidant enzymes activity such as Peroxidase, Glotation Reductase, Ascorbate Peroxidase and Catalase were studied. The observations indicate that Ascorbate Peroxidase, Peroxidase and Catalase activity in root and shoot was reduced in all the shortage level of mineral elements than blank level. But Peroxidase activity in phosphorous shortage was increased than blank level. In plants with Magnesium shortage, Glutation Reductase activity in root was decreased than blank. While in plants with Potassium, Calcium and Nitrogen, Glutation Reductase activity was increased. In relation with Glutation Reductase measurement in plants shoot with Nitrogen, Phosphorous and Magnesium shortage showed no significant changes, while in Calcium and Potassium shortage was decreased than blank level.
